The Courtesy Call

This first chapter will introduce you to the basic controls of the game and return you to the beginning areas of the original Portal. Listen to the Announcer and Wheatley's instructions to get through the first movement tutorial. Once gaining full control, you will still be missing a portal gun; however the system will automatically form portals for you. Move through the orange portal on your left and then right through the door to the next passage. Here, grab the cub that drops and place it on the red pad, which will open the door to the next area. Take the elevator down to the first level of testing.

Floor 1

Because you still lack a portal gun, you will need to hit switches to turn on blue portals. There will also be an orange portal placed behind you. First hit the switch on the right and enter the portal to grab the cube. Return to the center and hit the left button, allowing access to the red pad. Enter the orange portal and leave the cube on the pad to unlock the door. Return back into the center and press the middle button to place the last blue portal. Take the orange portal again to reach the exit.

Floor 2

Start by moving forward to the portal gun stand. The ground will break below you, causing you to fall into the waters below. Move forward up the short stair case to gain the blue portal gun. Fire a blur portal and exit through the generated orange portal. Move right and head down the corridors until located the next automated orange portal. Fire a blue portal and exit through the orange one. Turn to the left and fire another blue portal near the exit. Backtrack through the orange portal and arrive at the exit.

Floor 3

Head down into the pit and fire a blue portal. Grab the cube that falls below and carry it through the portal. Drop off the cube on the red pad to unlock the door to the next area. In this room, fire a portal down the pit to the right. Grab the cube from there and enter the portal. Drop the cube down to the main area and fire a new portal to the second cube on the opposite platform. Head backwards and pick up the second cube through the portals and drop down. Place both cubes down to unlock the door ahead. In this next room place another blue portal to move through the orange portal on the roof. Move ahead and reach the elevator to the next floor.

Floor 4

Place a blue portal on the floor and exit from the already placed orange portal. Press the switch on the right and form a portal below the cube that drops. Take the cube and place it on the red pad to the right. This will construct a set of stairs on the left. Climb up these steps and shoot a portal on the diagonal platform. Hit the switch on the left to release the cube and the switch on the right to prevent it from entering the water. Grab this second cube and place it on the red platform at the top of the stairs. Enter the now unlocked door to reach the next floor.

Floor 5

On this floor fire a blue portal to exit out the orange portal above. Look down the long pit and fire another blue portal. Drop down and use the speed of the fall to propel you to the other side. Look down the hole to the left to locate a cube. Fire a portal here to release the cube back to the pit area. Hop back down and replace the blue portal at the bottom of the pit. Grab the cube and once again leap down below. Place the cube on the red pad on the right and enter the next room.

For this room place a blue portal on the tilted platform on the left. Jump down the pit below to enter the orange portal and be thrown to the cube above. From where you land, place a blue portal on the left side of the wall in front of you. Grab the box and drop down the orange portal. Place the cube on the red button to raise a platform leading to the exit. Drop back down the orange portal again to reach the elevator to the next floor.

Floor 6

Move forward and place a portal behind Wheatley. Enter the orange portal to get to the other side. Wait for Wheatley to blab and drop down to your level. Pick up the personality sphere and insert him into the node on the wall. Look away to give him some privacy, and return when he says he's ready. Pick Wheatley up and head down the new passage.

Floor 7

Head forward to the other end of the room and drop down the broken stairs. Head down the underground pad and place Wheatley in the main breaker room. After a short scene you'll find yourself in the incinerator room. Move forward and grab the dual blue-orange portal gun. Place an orange portal above and a blue one to the left to move beyond the barrier ahead. Set down another set of portals to get through the next barrier. In this next hallway place one portal on the tilted wall and the second in front of you. Enter through the portals and move to the right. Shoot another blue portal above and another orange on the left wall to reach the floor above. Fire another orange portal into the next room. Move down the path on the left to reach the floor's elevator, ending the chapter.

The Cold Boot

Floor 1

Move across the room and stand on the lift. Fire a portal below the laser and second portal above the laser sensor. The lift will raise and take you to the elevator.

Floor 2

Jump over the laser and place a portal on the ground. Place the other portal below the laser reflection cube behind the barrier to grab this object. Place the box in front of the laser to change its direction and point it at the laser node. Climb up the steps that form and place a portal on the ground of this level. Place a second portal below the cube to bring it up to your level. Place the cube on the red button to open the door to the elevator.

Floor 3

Place a portal next to you and another portal on the above level to reach the top. Now place one portal directly below the laser sensor node and the other one the right wall to catch the laser from the left wall. Grab the cube on this level and leap across the platform. Point the cube near the second node to redirect the laser. This will open the door to the elevator.

Floor 4

Place an orange portal on wall to the left and a blue one across the way in the nook on the left. Enter the portal and press the button here to gain a cube. Fire a blue portal across wall ahead to catch the laser. As long as you used the blue portal, the laser will reach through to the laser node. Grab the cube and ride the platform to the other end. Grab jump over the laser with the cube in your hands to avoid interrupting your ride. Place the cube on the button and enter the elevator to the next floor.

Floor 5

Step on the jump platform to wind up on the other end of the pit. Press the button here and it will release a cube in the center of the room. Use the jump platforms again to grab the cube in midair. Land back down at the switch platform and place the cube on the large red button, revealing the elevator.

Floor 6

Move straight down to the other end of the hall. Turn around and place portals on both of the tilted platforms. Take the jump platforms through the portals and arrive at the other side of the room. Press the button to release some junk and a cube that arrive at your location. Grab the sub before it falls (Or follow it below if you miss). Place a portal to the right wall and one above the switch pad. Drop the cube through the portal to open the door to the elevator.

Floor 7

Grab the cube ahead and place it to obstruct the laser. This will lower the lift to the next area. Place a portal below the cube and another one on the wall to free up the laser and restart the lift. Once reaching the top place an orange portal on the further tilted platform and a blue portal below the cube to bring it to your current level. Grab the cube and jump through the blue portal below. The momentum will be enough to bring you to the opposite ledge with a button pad. Leave the cube here and shoot another orange portal on the other tilted platform. Drop down through the blue portal and allow the speed to take you to the exit elevator.

Floor 8

Move right, through the grill. These barriers will destroy objects and disable any formed portals, so you'll need to work around these. Press the button on the left to release a reflection cube. Fire a blue portal through the small round opening and a blue portal behind you. Enter the portal and pick up the cube. Return to the other side with the reflector in hand and align it so that the laser hits the sensor. Head back through the grill and right again to reach the elevator to end the chapter.

The Return

Floor 1

Place a blue portal directly above the jump pad and your orange portal on the long panel in front of you (it is slightly hidden by the broken black walls). Use the jump pad four times (the first three will be for plot development) to exit out your orange portal. On the above level place an orange portal on the tilted platform on the right side of the laser. Take the jump pad again and you'll arrive at a switch. Press this to release a reflection cube on the other side. From here place your orange portal on the other tilted platform and jump down to the jump pad, springing you up to the cube. Take the cube and align it with the short wall on the left. Now face the wall, but fire your orange portal at the third tilted platform on the left. Jump down back to the jump pad and you'll be taken to the top floor. From here place both your portals on either end of the small wall to let the laser pass through, unlocking the door to the elevator.

Floor 2

After entering the room, turn around and place a blue portal far above the entrance door. Next move over to the pit ahead and fire your orange portal below. Drop down through the orange portal and you'll land on the ledge with the cube. With the cube in hand, return to the main level and use the jump pad to reach the second floor. Place the cube into the laser's path to block the node, lowering the glass wall. Head back down to the main floor and use the jump pad to reach the third floor.

Press the button the right to release a reflection cube. Fire a blue portal onto the wall to the left so that aligns with the laser sensor node. Afterwards, head back down to the second level. Replace the normal cube with the reflective one and place your orange portal on the far wall ahead. Grab the normal weighted cube and use the jump pad yet again. Upon landing, place the weighted cube on the button to open the elevator entrance.

Floor 3

Shoot a blue portal against the end of the light bridge to gain it into your possession. Place an orange portal on the other side of the room and move through your light bridge to reach the button. Hit the switch and weighted cubes will continually fall on the left side. Return back to the other end and place an orange portal on the center wall. Go through your blue portal and onto the center bridge.When you reach a dead end, place an orange portal on the wall on the left, walk down, and place one more orange portal on the floor on the right below.This will form a light bridge that will catch the falling cube.

Grab the weighted cube and move through the portal behind you, back to the start. from the beginning area, place your orange portal on the right hand wall to bring the light bridge to the cube button. Enter the blue portal and walk across the bridge. Drop off the weighted cube on the button and place an orange portal below to return to the start. Place an orange portal yet again near the door and switch to reach the elevator.

Floor 4

Put an orange portal above the light bridge and your blue portal on the wall ahead of the entrance. Go through the blue portal and place a second orange portal at the true end of the light bridge. Enter the orange portal to return to the main area. Shoot your blue portal at the lone tilted wall on the left and hit the switch. This will drop a cube that will land safely on the light bridge. Grab the cube and move through the blue portal. Once through the orange portal, turn around and fire another blue portal on the left wall. The light bridge will now be pointing towards the exit door. Take the weighted cube through the portal and place it on the weight button, unlocking the door to the elevator.

Floor 5

Right in front of you will be a turret facing away. Grab it or bump it to shut it down. Fire your blue portal at the wall ahead and quickly turn the corner. Avoid the next turret's laser sights and place an orange portal behind it. Walk through your blue portal to take down the turret. Around the next corner, place your orange portal below the turret to take down the next enemy. Move on and you'll come to a room with two turrets and three cubes. Place a portal above the turret and one below a cube to squash the enemies under your box. Do the same with the other turret. In the next area place a portal below the turret closest to the door. Next, place your orange portal on the left wall and a portal above the turret facing away from you. Drop a cube through your orange portal to take out this enemy. Place another blue portal above the last turret. With all the enemies defeated, take a cube and place it on the button to open the exit.

Floor 6

Move forward and take the lift to the main level. Take the reflection cube and place it in front of the center and right nodes. Place a blue portal behind the right node and your orange one behind the left. With the lasers in place the door will unlock, leading to the elevator.

Floor 7

Place your blue portal at the end of the light bridge and your orange portal in front of the lone turret to block its laser sights. Enter the orange portal and knock over the four turrets ahead. Place down a new blue portal and move through to take down the original lone turret. Restore the blue portal to obtain the light bridge and move into the next large room.

In here, place an orange portal on the pillar to the right to block the cluster of turrets. Move towards the jump pad but don't get on yet. Instead, fire your orange portal above to form a wall with the light bridge. Use the pad and reach the top floor drop down the hole ahead and take out the four turrets. Now pick up the weighted cube and move to the main floor. Place your orange portal on the pillars ahead to form a wall of protection and drop the cube on the button. Move out of the sights of the next pair of turrets and place your orange portal above them. Quickly move back into cover and place your blue portal to take out the enemies and reach the elevator.

Floor 8

Place your orange portal below the laser and your blue portal in front of the enemy turrets. Stand on the switch and let the laser destroy the first three turrets. Take the normal weighted cube and place it on the button. Grab the reflection cube and use it to kill off the next three turrets. Afterwards use the same cube to align the laser with the sensor node. This will unlock the doors leading to the elevator.

Floor 9

Place your blue portal at the end of the light bridge and your orange portal on the wall to the right. Enter the orange portal until you are near the laser. Turn around and fire your orange onto the wall on the right. Pick up the cube and enter the blue portal. Drop the cube in front of the laser so that it blocks the node, lowering the lift. Stand on the lift and turn back around; place any other portal to disrupt the light bridge and lower the cube onto the button. If everything was placed correctly the lift will bring you to the open elevator door.

The Surprise

Floor 1

Get into cover behind the light bridge and fire your orange portal at the white wall on the other end of the room. Quickly move into the alcove on the left and fire your blue portal here. Next fire your blue portal at the end of the light bridge and your orange portal in front of the reflection cube dispensers. Press the switch to your right and if the bridge is placed correctly it will bring both cubes down to the main area. Fire another orange portal behind yourself and return to the main area. Grab the two cubes, using your orange portal and light bridge to provide cover from the current. Place one cube under the laser so that it hits the first two nodes. With the second cube align it near the turret so that it explodes. When it is save move the cube to the far right edge and align it with all three of the laser nodes. Fire an orange portal on the left wall to bring the bridge near the door, leading to the elevator.

Floor 2

Drop down to the main floor and place your blue portal on the ceiling above the first reflection cue. Put your orange portal on the ground drop through to grab the first cube. Drop back down and place your blue portal in the small alcove where the laser is shooting from. Place one of the cubes here and reflect the laser into the first node. return to the bottom and place a blue portal above the jump pad. Drop the next cube into the orange portal so that it bounces against the jump pad. When the cube is far enough above the orange portal, place your blue portal on the wall above wall to the right. This will launch the cube next to the second node. Now repeat the same process but instead of sending a cube down, enter the orange portal yourself and slam against the jump platform. When you're far enough above the orange portal place the blue portal on the same wall to reach the node and cube. Place the cube so that it hits the third node and return to the main floor.

Enter the orange portal drop-blue portal jump pad again for a second time, but this time fire the blue portal onto the wall on the right side of the main entrance. This will knock the third reflection cube, placing it near the entrance. Put your blue portal back at the entrance and drop down the orange portal. From here use the cube to destroy the enemy turrets on the other end before pointing the laser's flow to the final node. Return down to the bottom and place your blue portal back above the jump pad. Once again take the jump pad ride one more time, this time firing the blue portal at the far corner just right of the main door. If placed correctly you'll land right near the main door way.

Floor 3

Place your blue portal on the pillar to the right so that it faces all three of the nodes. Return to the main room and place your orange portal on the wall where the laser touches. Arrange the next two reflection cubes so that the lasers enter the orange portal, hitting the nodes on the right and center. With all three nodes in operation, the elevator entrance will open.

Floor 4

Shoot your blue portal on the wall on the right and your orange portal on the panel above. This will drop a box onto the light bridge. However, the power will shut off and the test will end. Follow Wheatley through the new door, but be quick as poison gas will start to flood the area. Head down the catwalk and across the light bridge to the right.

Floor 5

Keep following Wheatley and take cover to avoid the enemies. Sneak behind the three turrets and take them down to clear the area. Place your orange portal against the wall on the right, then turn to the left and fire your blue portal at the pillar through the small hole. Enter through the portal and follow Wheatley along the linier catwalk. You'll eventually come to a lift leading to the next chapter.

The Escape

Floor 1

The door ahead will not open fully. You'll need to fire your blue portal through the door and your orange portal to the left. Enter the portal and run along the catwalk. You'll come to an inactive conveyor belt. Run along this machinery and leap to the left across more catwalks. Leap down to the ride the assembly lines and run quickly to avoid being crushed or burned. Turn to the left and run down more catwalks, making sure to jump over the broken floors. Fire the blue portal at the wall at the end, look above to the small room and fire your orange portal. Move through the portals and drop to the next area. Shoot your orange portal across the chasm and your blue portal at any nearby wall. Enter the portals and fire a blue portal at the next wall ahead. Re-enter the orange portal to arrive at the next catwalk. Keep moving forward and you'll arrive at a room with a large spiral tube. Ride this tube down to the door below, leading to the next area.

Floor 2

In the next room place your blue portal on the wall over looking the conveyor belt. Make your orange portal on the wall behind you and enter it to land on the belt. Ride the belt to the other side and run over the ducts to reach the second belt. Ride this one to the next catwalk and follow the path passed the grill. Place your orange portal on the above wall beyond the glass window. Next place your blue portal anywhere nearby and travel to the small room. Place your next orange portal across the hall over the banister. Wait for a defective turret to come to the test area and shoot a blue portal behind its intended target. The defective turrets won't fire, allowing you to slip by unharmed. Enter the next room and meet with Wheatley again. Let him "hack" the door to gain access to the turret control room. Place down your portals to enter the small turret control room and remove the test turret. Return to the catwalk and grab a defective turret as it's flying towards the garbage. Place the defective turret in the control scanner and move to the next area.

Floor 3

Take the lift ahead to reach the top catwalk. Press the button on the right and it will open the door on the left. Before moving on shoot your blue portal at the wall that is being hit with the laser beam. Move through the door and use your orange portal to summon the laser against the moving walls. This laser will be enough to destroy all eight tubes connecting to the toxin. Return to Wheatley to enter the next area.

Floor 4

Place your blue portal on the flashing ceiling off in the distance, while your orange portal may be anywhere nearby. Move into the portals and land in a chasm. Attempt to open the door ahead and the room will reform, dropping you below. After a scene grab Wheatley and place him on the node. Move up the steps and place your blue portal on the white floor. Put your orange portal on either wall of the now open room. Enter the portals and place your blue portal on the opposite wall. Return through the portal to get by the defenses and reach the switch. Press this last button to end the chapter.

The Fall

Floor 1

Move through the tubes on the left and you'll come to a wall separated by a fence. Fire your orange portal on the wall in front of you and the blue portal through the fence, hitting the wall on the other side. After moving through the blue portal, look to the above left and place your orange portal. Move back through the portals to wind up on the other end. Head to the left and down the hill to reach another fence. Fire your orange portal ahead and your blue portal above the catwalk in the distance. Enter the portals and drop down to the lower floor. Head left up the next ramp, and to the right wall. Place your orange portal here and look above to the catwalk high overhead. Put your blue portal up there and head across the walk way. At the end of the path set your orange portal at the bottom and head back down to the ground floor.

Continue to the restricted area and flip the switch to unlock the gate ahead. Place your orange portal on the left wall above the catwalk. Next put a blue portal on any where on the white wall in front of you. Enter the portals to arrive at the catwalk on the left side of the room. Shoot your blue portal across the room near the second catwalk. Hit the button nearby, head through the portals and hit the second button before time runs out. This will open the vault door, leading to the next zone.

Floor 2

Move to the top of the catwalk and place an orange portal through the broken door. Put your blue portal nearby and head through it. On this end hit the switch to reach Aperture Science Innovators. Place one portal on the wall high above near the rafters. Your second portal should be placed anywhere in order to reach the top. Once on top of the structure, fire two portals below: one on the diagonal pillar, and the other straight down on the floor. Leap down through the portal on the ground and you'll be launched through the Aperture logo. Move through the lobby and out the next door ahead to reach the spiraling tower. Ride the lift ahead to the top. From here fire a blue portal at the diagonal roof far off to the left. Move a few levels down the tower and peer down the elevator shaft. Fire an orange portal down the bottom and leap down. The momentum will be enough to toss you safely to the next catwalk. Head through the next door and you'll arrive at a number of catwalks. Fire one portal to the wall on the right and the second above, over the top catwalk. Head through the portals and down across the pipes to reach the elevator.

Floor 3

First, bounce over the blue gel to the other side of the room. Place your blue portal in front and turn to the upper ledge on the left. Fire your orange portal here up and head through your blue portal. Bounce across the blue gel again and hit the switch on the other side to release a weighted cube. Drop back down to the main are and grab the cube, return through your portals, and place your cube on the weighted switch. Bounce forward again to exit the room through a grill. Climb up the next flight of stairs and place an orange portal over the catwalk above. Turn the corner and place your blue portal on the left wall to reach the upper catwalk. From here head left off the catwalk and left again up the stairs to reach another puzzle.

When you enter the room, turn right and place your blue portal on the ceiling above the moving platform. Next, turn left again and shoot your orange portal on the wall right above the blue gel. Bounce on the gel and enter your orange portal just as the moving platform is under your blue portal. Ride this platform and grab the weighted cube on the right. Move off the platform and put your blue portal on the left, right next to the weighted red switch. Pick up the cube again and bounce across the blue gel, back into your portals, and drop the cube off on the switch. This button will cause a panel on the far upper-right to flip around, revealing a white surface. Place your orange portal on this new panel, re-enter your blue portal and bounce towards another grill. In this room bounce across the blue gel on either wall to obtain the cube on the other side. Bring the cube back to the start of the room and leave it on the weighted button to reveal another new white panel. Head back through the grill and place your blue portal on this wall. Head back down to the bottom and place your orange portal above the gel again. Travel through your portals to reach the elevator to the next floor.

Floor 4

Drop down and move across the broken supports to reach the island on the right. Once here, look at the very top of the far right pillar emerging from the water and place your blue portal at the top. Move to any of the other pillars and shoot your orange portal to reach the top. From here, face the left and place your orange portal to gain access to the next room. The switch right in front of you will dispense blue gel that will stick to the walls and floor. Start by placing your blue portal in the far left corner near the upper level. Next, shoot your blue portal on the small white wall on the upper level.

Once reaching the third level, turn back around and place your blue portal on the wall directly below you so that the ground also becomes covered in gel. Finally, place your portal on the ground just under the grill ahead. Wait for the blue gel to fly up above your portal and then quickly remove your portal so that the goo can splat down on the ground. With both floors covered with gel, bounce forward and leap through the grill. Because the emancipation grill will have nuked your old portals, weave around to the left and replace your lost orange portal below the gel dispenser. Put your blue portal on the tilted platform on the left to send more goo flying onto the third level. Finally place your orange portal down below and leap into it. As long as the blue gel is in the right spot, the momentum of the fall will bring you to the elevator.

Floor 5

This floor contains both falling blue gel, as well as a steady stream of water that will wash away any gel it contacts. Place your orange portal below the gel and your blue portal on the ceiling over the switch above you. Once the gel slams down on the ground below the switch, jump on it and activate the button. This will disable the water, but only for a short time. During this moment, replace your blue portal onto the wall on the left. Once the gel lands, leap on it quickly to reach a grill to the next section.

First place your orange portal below the dripping blue gel and your blue portal on the tilted wall. After the right hand wall is gooed up, place your blue portal on the very top of the back wall, above the support beams. Once up here fire your blue portal back at its first spot (The tilted wall) and your orange portal on the floor far below you. Leap into your orange portal to bounce across the wall and emerge through a second grill.

You'll have an overhead few of the first room, allowing you a chance to place your orange portal below the gel dispenser. Once this is complete, move up the stairs and set your blue portal on the upper white section of the second pillar. Once the ledge is covered in blue gel, look over the edge of the broken lift and drop your orange portal on the floor below. Leap into your new placed portal to be bounced around to the lower catwalk. Face the pillar's right side and place two new portals on the lower and upper catwalk to ascend to the upper floor.

From here you'll reach another puzzle room passed a grill. There is both a water and gel dispensers here. Place your orange portal under the gel and your blue portal over the encased weighted cube to break it free. The cube will bounce around like crazy, so grab it and place it in the water to clean it. Place the box on the weighted button to lower the lift ahead. Place your blue portal directly under the lift and let the gel splash the floor. Move your portal anywhere to clear the floor and leap onto the lift. Shoot your blue portal right above the weighted cube to dislodge it, raising the lift towards the exit elevator.

Floor 6

After exiting the elevator, shoot a portal on the far wall over the chasm. Enter the building ahead and place your other portal on the wall to the left to gain passage to the far catwalk. After moving to the right, open the door and enter the main room. Shoot your blue portal on the floor just in front of you. Look above and place your orange portal above the catwalk. Move through your portals to reach the top and place your orange portal directly below the end of the catwalk. Drop into your portal so that you gain a good amount of speed. When you emerge from your blue portal, fire your orange portal on the left wall. When you drop back through your portals you'll be thrown safely to the offices above. Hit both gel control leavers and move through the open door on the left.

In the next large area place your blue portal above the stable section of the catwalk and your orange portal directly in front of the boarded up door. Head up to the top catwalk via your portals and place a new blue portal on the tilted wall on the right. Jump off the catwalk into your orange portal to reach the second floor of the Aperture building. Move over to the nest and tag GLaDOS. Unlike other objects you can freely fire your portal gun while carrying her. Exit back out to the main area and place your blue portal back above the catwalk. Step back into your orange portal at arrive at the top again. Face the wall behind you and place your blue portal as high as possible so that it aligns with the elevator. Jump back through your orange portal to sail through the air to the exit.

The Reunion

Floor 1

This floor introduces orange speed gel that will allow you to run quickly. In the first area place your orange portal below the dispenser tube and your blue portal on the small ceiling. Drop through your portals and land on the ledge. Face the wall on the right and move your blue portal on the lower wall. Hit the button next to you to send speed slime all over the ground. Next, replace the blue portal on the above ceiling. Drop back down and slide across the orange gel to reach the other side. Put your orange portal on the left wall and head in to wind up on the ledge again.

Put your blue portal below the dispenser and hit the switch to goo the second room. Run over the gel again and wind up in the last room. Set up your portals to grab the weighted cube and bring it back to the main room. Set the weighted cube on the button and fly to the upper levels. Place a portal on the floor below and one behind the slimed path. Head back through your portals and run at top speeds to reach the switch, opening the door. Head through two grills to arrive at the next test room.

This section has both blue and orange gel. Remember that each gel will overwrite one another. First fire a portal on the pillar to the left and the other portal under the orange gel dispenser. Let the orange gel loose to goo up most of the area with speed gel. Next put a portal under the blue gel dispenser and your other portal on the lone ceiling pad. Blue gel the far edge and speed jump to the catwalk ahead. Place your blue portal at the top of the pillar and your orange portal below. Face back towards the main area and place your orange portal to get back there. Last put your orange portal on this side of the pillar and run back through the gel. With the two portals in place you'll arrive at the exit elevator.

Floor 2

You'll once again have access to both orange and blue gel. However, most of the floor is grated, so gel will be un able to stick. Start off by placing your orange portal on the far right tilted wall and your blue portal under the blue gel tube. After the other incline is covered in blue gel, place your orange portal on the vertical wall just below its previous location. Now put your blue portal under the orange gel and allow the runway to become covered in speed gel. Enter the portals to arrive at the runway and place your blue portal on the tilted wall behind you. Move to the other edge of the orange goo and run through your portals; your placed orange and blue gels will be enough to catapult you all the way to the far off platform where a weighted cube rests.

From your current position place a portal back under the blue gel tube and you're second directly under the rotating platform controlled by the weighted switch. Once this is done switch your portals to allow access to the weighted switch on the far left. Leave the cube on this switch to rotate your now blue gel covered platform. Set you portals again to return to the runway area and place your blue portal on the straight wall. Once your blue is in place, look slightly above and to the left to spot another ramp and white wall. Shoot your orange portal at this wall and run through the orange gel covering the run way. The amount of speed and the rotated platform will be enough to jet you over to the exit elevator.

Floor 3

Place one portal on the catwalk to the left and another on any other wall. Head through the portal and passed the grill. Upon exiting, place a portal on along your current catwalk, and a second off high to the right near the "Pump Station Gamma" sign. Walk through your portal and into yet another grill. Enter the control room to release blue and orange gel, along with extra white paint. Place a portal near you and one back at the entrance to avoid the crushing pumps.

Place a portal on the now white covered ceiling to land on the broken catwalk. Jump down unto the spilled blue gel to arrive at the higher level and another grill. Place a blue portal on the right wall and run over the orange gel to reach the other end. Exit through the door on the right and place your orange portal on the tilted wall. Return to the previous room and run across the orange gel, into your blue portal, and out over the chasm. You'll arrive at Johnson's enrichment center. Enter the room on the right to release the locked door. Head passed the waiting area and up to the next floor.

This next area has a tube gushing white paint. Throw down two portals close to the tube to send the paint out of its pen and to the two large pillars on the left. Once either interior side of the pillars is covered with white paint, keep moving your portal up the pillars until pain covers every inch. Finally place on portal at the top of the right hand pillar to reach the top. Move over to the edge and place your orange portal on the tilted platform. Move to the other side of the pillar and place your blue platform directly below you. Jump down through the blue platform to be sped over to the catwalks where the exit to the next area awaits.

The next area is rather simple, but a tad long: keep making portals at higher levels from your own to reach the top. Eventually you'll reach a broken elevator. Place your blue portal on the floor and move over to the broken catwalk. Place your orange portal below and jump in. You'll land on a ledge to the right where you should replace your orange portal. Jump back down into the elevator to emerge through your next orange portal and quickly place a new blue portal on the tilted wall. As you fall back into your orange portal you'll arrive at the exit door.

Floor 4

Start off by placing your orange portal at the top of any of the four pillars and your blue portal at the bottom. Face the wall with the three large pipes and fire your orange portal on the tilted wall. Look over the edge and fire a blue portal and then leap down into it. You'll fly over to the second level where you some blue gel is dripping. Place your blue portal below this drop to pass the jump goo until the second diagonal floor. Place your blue portal down the hole below and drop down to wind up on the third floor. Here put your orange portal on the ground and leap back through your blue portal. As you emerge from your orange portal, fire your blue portal again to gain access to the fourth level. Move passed the grill ahead to reach a room with both types of gel and white paint.

Place one portal below the flowing white pain and another on the ceiling grate right over the tilted wall. Once this wall is painted, place your blue portal on the upper wall and your orange portal below the orange speed gel. Once the ground is covered place your orange portal on the tilted wall and use the gel to run through the portals, landing on the second floor. Place your orange portal below the white paint stream and your blue portal on the bare ground ahead. Once the roof is covered in white, place your blue portal on the ceiling and your orange portal under the blue gel drip. Return to the previous level and set your portals again to get to the second level. With your new blue jump gel in place, you'll be taken to the next floor.

Up here place your blue portal on the dripping white paint, and your orange portal up the top of the shaft to warp inside. From here walk to the other end and place your orange portal on the left tilted wall. This will cover the area with paint allowing you to place another blue portal at the top of the long shaft. Return to the small room and place your orange portal to reach inside the shaft. Walk all the way up to the large grate and fire a portal through the barrier. Next return to the lone white floor in the shaft and put another portal to enter the gel control room. Place a portal on the top catwalk and one below to transport to this broken rail. Once up top, move to the very edge and place one portal on the white paint to the far right. Look directly below and fire your other portal; leap down and use momentum to take you to the hatch override. Press the button and ride the new lift to the top.

The Itch

Floor 1

Move into the small room and place a portal on the wall. Search the small broken shaft on the right and fire your other portal to gain access to the lower catwalks. Move along these rails to reach the lift on the far right. Keep moving through the area and stop to complete Wheatley's minor test: place one of the sentry cubes on the weight. Afterwards continue forward and hit the switch to release another cube that will land right on the weighted button. Set up two portals to reach the exit goal. Wheatley will have you complete the same room a second time. Do so and this time the real exit elevator will appear.

Floor 2

This stage introduces the light energy tunnels. Start by first riding the light up to the second level and placing your orange portal above. Fire your blue portal on the lone white corner just above the exit door. Ride the light beam to gain the cube on top. Place new portals to arrive back on the bottom with your cube. Place your cube directly under the button and a new portal over the light tunnel. Finally place your other portal under the cube and button to force the cube into the button, opening the door to the elevator.

Floor 3

Shoot your blue portal on the wall to the right. Drop down into the light tunnel and hit the wall with your orange portal. Ride through the portals and when your reach the intersection, shoot your blue portal on the small checkered floor to the left. Ride this new vertical tunnel to the top of the platform where a switch rests. Shoot your blue portal below the cube drop point and hit the switch to dispense a cube. Once it hovers over the checkered floor, replace the blue portal there to bring the cube to your level. Place the cube on the next white floor, as well as your blue portal to hit the button above. The door will unlock, leading to the floor's elevator exit.

Floor 4

Fire your blue portal over the end of the tunnel and your other orange portal in the left corner to create a shaft to the other end of the room. Over here, set your orange portal in the center so that it's directly under the cube dispenser. Hit the switch to release the cube and let it float to the right. Once it can go no further, fire your orange portal on the white panel behind the cube to bring it to your own platform. Now place your orange portal in front of the black and blue target to create a safe landing pad.

Grab the weighted cube and leap on the nearby jump pad to reach the light tunnel and arrive back at the main room. Leave the cube on the checked path and put one portal at the highest point of the back wall (between the checkered floor and ceiling). Now put a portal under your own feet to leap down in front of the locked door.

Place another blue portal at the end of the light tunnel and your orange portal below the weighted cube so that it raises to the lowest white squared wall between the checkered floor and ceiling. When it reaches here, shoot an orange portal behind the cube to have it smack against the button, opening the locked door. Proceed to the elevator to arrive at the next floor.

Floor 5

Place your blue portal on the checkered wall on the right so that it catches the light beam tunnel. Place your orange portal in front of the turret's laser sights to knock it into the bottomless pit. Next shoot your orange portal on the left wall so that it catches the weighted cube.

Stand on the red switch to alter the current's flow and send the cube into the corner. Hit the other wall in the same corner with your orange portal to send the weighted cube to your side. Place the cube on the button and ride the tunnel back to the other side. Now readjust the beam so that it knocks the weighted cube into the bottomless pit. Place one last orange portal on the floor ahead to float to the top and take the elevator to the bottom.

Floor 6

Fire your blue portal at the end of the light tunnel. Next shoot your orange portal on either on the small white panels behind you. Ride this tunnel to the center panel and place your orange portal here. as you ride up to the top, fire your blue portal on the tilted platform ahead to launch to the exit with a button. Replace the light tunnel portals so that the tunnel emits from the center column. Hit the button in front of you to launch the weighted cube into the vertical light shaft. Next, drop the beam by placing your other portal on the same tilted platform to bring the cube to your area. Drop the cube on the large weight switch to gain access to the elevator.

Floor 7

Put your orange portal at the end of the light bridge and your blue portal around the third section of the grill. Hit the switch near bay to launch a weighted cube that will smash into the light bridge. Form another set of portals below to quickly grab the cube. evade turret fire, and bring it up to the main level. Once again return your orange portal to the end of the light bridge. This time look up and place your blue portal so that it's over the catwalk. Grab the cube, hit the jump pad and land on the upper level.

Before moving along, shoot your blue portal back in the turret pit to block off their sensors. Take the weighted cube behind the grill and place the cube on the weight button. Afterwards head into the tiny nook and place your blue portal to escape. Once again place your blue portal over the catwalk to form a barrier and take the jump pad to the second floor, and march to the next floor.

Floor 8

First place a blue portal under the light tunnel and your orange portal on the checkered panel directly near the front entrance. Use the tunnel to float up to the top and shoot your blue portal at the tilted target in front of you. You'll speed through your two portals and land on a platform with a weighted cube. Grab the cube and use it to block the laser beam on the left side of the room. Head back up to the main floor and place portals on the two tilted platforms in the room. Jump on the single jump pad and you'll travel to where a reflection cube rests.

Replace the weighted cube with the reflector and take the weighted cube back to the top. Place the weighted cube on the checkered floor below the red weight button and ignore it for now. Set up your portals so that the laser below hits the laser sensor on the first floor. The First lift will drop, so get on it.

Next disrupt the laser flow by putting a portal under the reflector, which in turn raises the lifts and restarts the energy tunnel. put one portal under the tunnel and the other directly under the weighted cube. When the next lift lowers, get on it and dislodge the weighted cube by moving either portal. Once at the very top, move ahead through the door to reach the elevator.

Floor 9

There are two laser nodes in this stage: The bottom controls the movement of the platform, while the top one disables the laser field in the middle of the platform's path. Align your portals so that the laser reaches the bottom sensor, and let it slide to the left under the white wall.

Once there, make a new portal above the platform to safely land on top. From your new position re-align the lasers with your portals so that only half of the platform passes through the dangerous laser wall. Quickly switch around your portals so that the laser instead hits the top node, removing the danger. Walk onto the other side of the bridge--passed the laser wall, and hit the bottom node again to reach the cube control switch.

Let the platform return to the other side, just under the reflection cube dispenser. Hit the switch and let the cube land on the platform. Once again portal over to the shaft where the cube sits and safely take it to the other side of the laser wall. Leave your portals so that the laser emerges from the second highest white wall and gleans toward you and the cube.

Adjust the reflector cub so that it hits the sensor over the locked door. Jump down to the cube control again and place a portal to wind up on the other side. With the laser bouncing back to the main node, enter the door to reach the elevator.

Floor 10

Hit the switch right in front to lower a weighted cube. Place your blue portal over the light tunnel generator and your orange portal on the white wall behind both buttons. Stand on the weighted button and the tunnel will knock the weighted cube forward. Move your orange portal to the wall in front of the switches, causing the cube to drop and float towards you. Place portals to enter the small closed off room on the left and drag the weighted cube with you.

Leave the cube on the weighted button here and return to the main room. Back at the first room orange speed gel will now be spewing. Replace your blue portal over the light beam tunnel generator and your orange portal on the left wall under the orange gel tube. Stand on the tunnel's control switch and let the flowing gel fly overhead. When enough goo travels over the ramp and runway area replace your orange portal to deposit the slime all over the ground.

Once again move your portals to re-enter the small room on the left and bring the cube back to the main area. Place the weighted cube on the light tunnel controls and set up your portals to emit the tunnel from the right side room passed the ramp. You'll want the light tunnel as close to you as possible for this next step, so readjust the beam if it's too far. Slide over the speed gel on the ground and leap to the other end. If the light tunnel is placed correctly, you'll briskly travel to the exit elevator.

Floor 11

Put your orange portal under the blue gel dispenser and your blue portal any where else to travel to the other side. Once there put your blue portal on the other end of the light tunnel and press the button nearby. Jump gel will flow into the tunnel and towards the entrance. First disrupt the beam so that a small amount of blue gel splats on the lone black floor in front of you.

Next re-establish the stream, quickly hit the button and use the fallen gel to leap into the tunnel. You and the extra jump gel will float to the other side. Quickly get out of the beam and land on the weighted button to reverse the light tunnel flow. Let the gel pass through your portals back towards the light tunnel source. Shoot your exit portal over the turrets on the right and step off the button. When the gel is right over all three turrets, disrupt the beam to destroy all three enemies. If you need to re-adjust the gel's position you can always step back on the button to alter the tunnel's direction.

Move to the other side of the glass and hit the switch to reveal a tilted platform. Place your blue portal at the end of the light tunnel and your orange tunnel on the ground. Float up the tunnel and once you reach the top fire your blue portal onto the tilted platform. You'll have enough speed to fly and bounce over to the elevator.

The Part Where…

Floor 1

Step on the jump pad and travel along Wheatley's ride. You'll need to work fast as the deadly trap can kill you quickly. First shoot your blue portal on the dripping white gel and your orange portal on the lone white wall on the left. Once the gel splats on your platform move your blue portal under you to arrive on the catwalk. Walk along these rails until you come to a broken section.

Place one portal on the small white wall on the upper right and the other portal on the ground far below. Leap down into your ground portal to whisk over the air to the next rail. After the next trap smashes the rails, make a new portal to the left and a second high above the other catwalk. Travel to the other side and continue forward to reach the exit.

Floor 2

Wait for the walls to smash together before moving ahead. Once the destruction is over fire your orange portal at the white wall ahead and your blue portal through the grates overhead. Drop down into the next room and exit out to the other end of the catwalks. Eventually you'll run into three live turrets. To defend yourself place on portal on the end of the light tunnel and the other tunnel on the white wall behind the turrets to knock them out of place.

Next jump into the beam and float to the other side. Exit out of the beam to avoid the crushing machine and continue through the grill. In the next room place your orange portal under the light tunnel. Next place your blue portal on the white wall behind you to float across the chasm ahead. When the crushing spikes appear move your blue portal to the next new white surface that shows up. Once you're safe land on the catwalk and through another emancipation grill.

Spring over the jump gel and you'll arrive at another room with many turrets ahead. Place one portal on the wall to the right and another right above the broke window to wind up at a gel control room. Place your orange portal under the jump gel dispenser and stand on the button to let the goo flow.

Shot your orange portal repeatedly over the far wall on the right to flood the area with gel and destroy the multitude of turrets blocking your path. Once it's clear make more portals to reach the jump pad and leap back to the catwalk. Travel up the stairs to reach the exit.

Floor 3

Look out the smashed window and place your blue portal below the white section of the bomb tube. Next fire your orange portal on the white wall facing the white gel tubes. Hit the button in the room to bring the explosives in and liberate the goo. Place your orange portal on this new surface and travel to the other end.

Travel down the catwalks and over the conveyor belt. Place your orange portal under the bomb pipe and your blue portal under the orange gel tube. Hit the button ahead to bust open the speed gel and place your blue portal on the other end of the belt. Let the orange gel squirt all over the conveyor and run across to wind up on the other end.

Move on ahead and turn right twice. Fire your blue portal forward to soak the ground and your orange portal on the railed floor to the left, directly below the light tunnel above. Once on the other side drop down to the catwalks and through the grill. Set up a portal on the wall and the next one through the gate to complete this floor.

Floor 4

Fire one portal on the ground and a second on the roof behind you to reach the corrupted core chamber. Plug GLaDOS into the control panel to face the final boss. You have only five minutes to complete this fight before the toxins/explosions take you down.

First stand in front of the white gel tube and let Wheatley open it in the crossfire. Place a portal behind Wheatley and another on the ground just in front of you. Wait for him to shoot more bombs and he'll end up plugging himself in the back. Once he's down put another portal above the catwalk and grab the personality cube GLaDOS provides. Hop back down and use the next puddle of blue gel to place the core on Wheatley.

Once the robot wakes up again use the same bomb tactics to hit him again. Once again place your portals on the catwalk and bounce to pick up the next core to stick on Wheatley. Once he is operational use the bomb-portal attack for a third time.

This time some orange gel will break off in the far corner. Place your orange portal at the end of this gel and your blue portal under the last core. Race across the speed gel and pick up the core. Fire your blue portal on the highest tilted platform facing Wheatley and run through your portals to lodge the third core.

Place your orange portal on the white ground and your blue portal in the stalemate room. Travel over and you'll be blasted back by the bombs. Finally, shoot your blue portal at the bright white moon to complete Portal 2.

Team Building

Floor 1

Blue should stand on the weighted switch on the right and open the door. Orange should place their orange portal on the ground and move through the now open door. Blue will want to walk off the right button and onto the left one. Orange should now enter the new room made available to them and fire their red portal on the only white wall. Blue should then enter Orange's portal set to reach the floor elevator.

Floor 2

For this first puzzle Orange should shoot their orange portal on the wall on the right and their red portal on the other wall across the water. Next Orange should move through their portals and stand near the barrier. Blue will now need to hit the button and let Orange proceed in the next room. Orange will want to place their red portal in this room, allowing Blue to join up.

There will be four switches in this area. Both Blue and Orange will want to place each of their portals near each of these buttons so that all four can be pressed quickly. This will release a sphere that can be inserted to open the door to the elevator.

Floor 3

Blue will want to set their portal set on both sides of the right column while Orange will want to put their portals on the left column with these gateways placed, either player will want to grab the reflector tube and shine the laser into both nodes. This will unlock the next area separated by an emancipation grill.

For this next room Orange should stand on the weighted button to lower several platforms. This in turn will reveal several turrets waiting behind glass. Blue should hit the switch on the left and grab the reflector cube that drops. Blue should then take the cube near the vertical laser and use the reflection to destroy the turrets. After the turrets are destroyed Blue will want to place their portals on the two white walls ahead. Orange will now want to place one of their portals on the upper wall on the right, and their second portal on the wall behind the ground node. Re-adjust the laser so that it passes through all four portals and touches both nodes to complete the chamber.

Floor 4

On this floor your goal is to acquire the reflection cube trapped in a winding lift maze. There are five boxes in this maze that can be lowered with the left bottom, or raised with the right. Blue will want to set their purple portal on the ceiling of the only open window in the top left corner and their blue portal on any wall to get inside.

Blue will want to run forward as much as they can until they are blocked by the first box. Orange will now want to stand on the left switch and lower the boxes. Blue should move forward, drop down, and wait on the back floor. Orange should move over to the button on the right and raise the boxes. Next, Blue will want to drop down only once and wait on the black ground right before the next drop. Orange should now switch back and lower the boxes, allowing Blue to stand on top. Once Blue is in position, Orange should step off the button and allow Blue to grab the cube.

Once Blue has the reflector cube, Orange will want to stand on the left button again to lower the boxes. Blue will now want to fire their purple portal on the white wall to return to the main area. Take the cube over to the laser and set up portals to reflect the laser into the node, completing the stage.

Floor 5

Blue will want to pick up the reflection cube ahead and bring it over to the laser. Point the laser over to the first node on the left to raise the spike trap. Orange will want to move passed the trap and stand on the platform to the right. While here Orange should also place their red portal on the left white wall and their orange portal slightly further down this same area.

Blue will want to point the laser at the center node, which will lower Orange's lift but raise another one from the water. Orange will want to quickly run through their portals and on to the raising platform. Once Orange is high enough, Blue will want to move the laser over to the right node to raise the second spike trap. When the path is clear Orange should move forward again and turn right twice to hit the exit room. Orange will also want to place their orange portal on the white wall nearby.

Blue will want to again place the laser at the first left node, travel passed the spike trap, and into Orange's portals. With both players reunited, access to the elevator will be granted.

Floor 6

Either player should fire one portal at the end of the catwalk and another in the room below. Both players will want to enter this gateway as there is a grill in front of the next room. Once both players are inside, Blue will want to set their purple portal on any wall. Both players will need to hit the two switches on the wall to open the next door for a short time. While this opening is up Blue should shoot their blue portal into the open room. Travel through these portals and into the next room. First press the switch on the left to open the door and grab the large disc on the right. Take the disc to the front room and place it inside the drive to complete the level.

Mass And Velocity

Floor 1

Blue will want to set their purple portal on the small white floor and their blue portal at the top alcove on the left. Orange will need to place their red portal on the white wall sticking out overhead. Both players should enter the top alcove through Blue's portals. Orange should now fire their Red portal below, overwriting the purple portal. Both players will now need to leap into Orange's portals to reach the grill to the next area.

In the next area Orange will need to shoot their orange portal under the lift on the left, and set their red portal on the very high wall on the left. Blue will want to set one of their portals next to the top of the lift and the other portal on any nearby wall. Blue will next need to travel through their own portal set and then leap down through Orange's portals. Once landing on the other side Blue should stand on the switch. Orange will now need to move their red portal onto the high wall on the right. After doing so Orange should travel through Blue's portals, their own portals, and finally stand on the second switch. A sphere will drop, allowing both characters to advance to the exit.

Floor 2

Blue should set their portals in the small alcove with a grill in the center. Orange will now need to jump into the portals, as the portals would be destroyed if Blue entered. In turn Blue should move over to the switch and press it to move the barrier. Once this is done Blue should fire their top portal at the incline, which will launch Orange forward. From the other end Orange should repeat the solution for Blue: place their orange and red portals between the grill and fire at the incline to send Blue over. Once both players have been thrown around to the other side the exit will open.

Floor 3

Blue should once again place their portals on both sides of the horizontal grill. Orange will want to jump into these portals and wait for now. Blue will need to circle around the vertical grill and drop to the lower area. Blue must stand on the large weighted button and fire their top portal at the small white wall to the right. Orange will just shoot to the other side be near a sphere dispenser controls. Orange should let out a sphere and bring it to the stable ground where Blue is. Once Orange is back to safety, Blue should pass through the grill and up to the higher level. Orange should pass the sphere to Blue so that it doesn't have to be destroyed by the emancipation grid. Take the sphere to the exit and place it in the node to unlock the door.

Floor 4

Blue will need to first set their portals on both sides of the horizontal grill. As with Before, Orange should jump through these gateways to gain a burst of speed. Blue should then move back over to the starting area where two high switches are placed. They should place one of their portals below both switches, causing Orange to juggle between both floors. During this time Orange will need to hit both switches in short succession to release a sphere. Take this sphere to the door on the right to complete the level.

Floor 5

For this floor Blue will want to set their blue portal above the jump pad and the purple portal on the inclined ledge. Orange will want to step passed the grill and place both of their portals on both sides of the thin white wall overhead. Blue should next step on the jump pad and fly to the second level behind the grill. From here Blue should place their portal on the incline to the right. To reach the exit Orange will need to step on the jump pad and Blue can jut jump in their purple portal.

In this next area Blue will want to set their blue portal above the jump pad and their purple portal on the ground below the weighted cube. Blue will next need to use the jump pad to travel through and grab the cube. Drop the cube in the main area and switch the purple portal over to the incline facing the large grill. Orange should now use the jump pad and fly through Blue's portals.

From here Blue will need to grab the weighted cube and hand it to Orange. Orange should now leave the cube on the weighted button to reveal another grill. Blue should set their purple portal on the wall facing this new grill opening. Next, Orange should return to the jump pad and be launched into this new small room.

Orange should set both of their portals on both walls here and move out of the way. With all for portals set, Blue should use the jump pad to reach the exit. Place another blue portal next to the exit and the purple portal below to allow both players to move on.

Floor 6

Orange should first move through the emancipation grill and place their portals on both of the inclines to the right. Blue will want to set portals to reach the jump pad on the right. From this vantage point Blue will want to set their portals on the two inclines ahead and then use the jump pad. Blue will fly through all four portals and will land near the weighted cube controls. Hit the switch, catch the flying cube, and pass it down to Orange. Now both players will now need to switch their portals--Blue should shoot the two inclines from the balcony they are on; Orange will need to pass through the grill and put their portals on the other two inclines. Orange should use the jump pad to rejoin Blue and advance to the next room.

Blue will want to set their portals on the lone two white walls panels and use the jump pads. Due to the pad configuration, you may need to jump on them a second time to enter the portals. While Blue is flying around, Orange should press the switch and release a weighted cube. The expulsion of the cube needs to be timed so that it drops right in front of Blue as they pass through the portals. Once Blue has the cube, get off the pads and store the cube in the node to reveal the exit.

Floor 7

Both Orange and Blue should set their portals to slam into the switches on the wall. Both players will need to step on the jump pads at the same time to smack both buttons at once, opening the door to the next area.

Orange will next need to set one portal on the checkered wall on the left, and their other portal on the wall behind them (Which faces a laser sensor node). Orange should now grab the reflection cube and align the laser into the node, activating the lift. Once the lift is high enough Blue should leap through their portals and arrive on the other side of the crushers.

Both players should meet in the next room and bring the cube along. Blue should more near the locked door and Orange should use the jump pad to open the door to the other side. There will only be enough time for Blue to get through, as the door will shut tight again. Orange will need to set one portal above the exit door and the other near the jump pad. Drop the cube on the jump pad and head into the portals. When the cube hits the button, dash into the door. Move ahead to reach the exit.

Blue will want to set one portal on the checkered wall above the laser, stand on the lift, and place the second portal on the ground directly in front.

Floor 8

You'll need to use team work to grab the reflector cube from the tube in this area. Blue will want to place their portal on the lower incline and Orange will want to place their portal on the higher incline. Both players will want to put portals over the edge below. Blue should jump in their portals first to slam into the button. If a reflector cube is passing through the machine it will pop out in the next few seconds. Orange will need to enter their portals and snatch the cube as it flies through the air.

Orange should then set up portals to bring the cube to the starting area. With the reflector in hand, point the laser into the node ahead to stop the large fan. Blue should set their portals on the right side incline and another over the ledge from before. Drop down into the portal and wind up passed the fan.

Once inside Blue will want to stick one portal across from the laser sensor node (Between the computer and the white board). Move into the next room on the right and place the other portal next to the row of filing cabinets. Orange will next want to set one portal over the straight pillar with the "01" stamped on it, and their other portal on the small wall in front of the fan and laser beam.

Once all four portals are set correctly, Orange will need to point the laser to the node near Blue to turn off the fan. Now Orange must catapult passed the fan and meet up with Blue. Head over to the locked door on the left and both players will need to pull the leavers at the same time. Once the gate is open, head up the stairs and insert the disc into the drive to complete the area.

Hard-Light Surfaces

Floor 1

Blue should shoot their purple portal at the end of the hard light bridge and their blue portal at the wall on the left. Walk along the bridge and drop down to the second patch of gourd. Face left and move your blue to this white wall. Orange should walk along the light bridge into Blue's portals and out the other side. Fire one portal on the wall ahead and the other on the wall to the right. Both players can now walk through Orange's portals to reach the gate to the next zone.

In this next room Blue will have to place their purple portal at the end of the light bridge and the blue portal slightly below the grill overhead. Use the jam pad and slam into the bottom of the light bridge--as you descend back down place your blue portal further down the wall to land on the bridge. Blue should then enter their blue portal to wind up at the light bridge source.

Blue will then next need to move their blue portal out of the way and allow Orange to use the jump pad. Once gain, when Orange descends down Blue should place their blue portal so that Orange lands on the hard light bridge. Now on the bridge, Orange should shoot one portal at the other end of the bridge and the second portal near the button on the left. Head through these portals and press the button release a sphere at the ground level.

Orange will need to head back down and pick up the sphere, use the jump pad, and return to the light bridge. Remember: due to Orange carrying the sphere with them, Blue must be sure to first place the bridge under the grill, as this device will destroy the sphere. Once orange is up top, head over to the node and use it to exit the floor.

Floor 2

Blue will need to shoot their portals at the wall straight ahead and the other on the left. Orange should walk along the light bridge and place their orange portal at the wall to the left. Orange will then need to come back to the bridge source and place their red portal at the end of it (replacing one of Bleu's old portals).

Blue should walk through the red portal and place their blue portal on the wall to the right. Return back through the orange portal and place the purple portal over the red portal. Next, Orange must enter Blue's portals and place one portal at the wall ahead and their other portal high up on the right wall. The light bridge will now pass through all four portals, right to the floor's elevator.

Floor 3

Blue should first fire their portals to arrive on top of the light bridge. Once there, Blue should switch their portal so that their purple is at the end of hard bridge and their blue is below the sphere dispenser. Orange should move onto the bridge and fire one portal at the opposite end of the blue portal, and their second portal above the sphere sensor node. Blue should now hit the switch on the right, dispensing the sphere, which Orange must catch as it falls. Enter Orange's portals and drop off the sphere in the node to move on to the next area.

For this puzzle Blue should shoot their purple portal at the end of the light bridge above and the blue portal under the exit door. Orange should now shoot one portal on the opposite wall from the blue portal and another one in the small patch of light in the ceiling. This will create a wall directly in the jump pad's path. One at a time, both players should use the jump pad and enter the blue portal to the top of the light bridge. Once at the top, Blue should move their blue portal above Orange's portal on the wall. With the bridge now aligned towards the exit, move through the purple portal to finish the level.

Floor 4

Both players will need to do the following one at a time: Make one portal at the end of the light bridge and use the jump pad. As you start to fall, shoot your other portal below you, forming the light bridge. Walk through the portal to reach the next level and wait for your partner to complete the process. Afterwards, the second person to arrive at the top should shoot their lower portal at the incline overhead. Head through the portals to descend down to the exit that was above you.

For this level Blue should place their purple at the end of light bridge and the blue portal fall below the bridge. Enter through the portals and move across the bridge. Move the blue portal to one end of the chasm below. Orange will now need to enter Blue's portals to arrive at the light bridge. Shoot one portal at the opposite end of the blue portal and the other portal to the wall on the lower right. Both players should now enter Orange's portal to reach a few platforms that suddenly appear. From here Orange should pace one of their portals on the incline and their other on the small piece of floor over the waters below.

Blue should now shoot their blue portal at the white wall far off in the distance to bring the bridge over Orange's portal. Orange must now walk over the bridge and stand above their portal. Once in place, Blue should move their portal, disrupting the bridge, and causing Orange to fly to the exit. From here, Orange should place portals to allow Blue to reach the top as well, concluding the stage.

Floor 5

Orange should start out by placing their orange portal above the jump pad and their right portal to either side of the floor below the bridge. Blue should now head to the jump pad, through Orange's portals, and to the top of the light bridge. Orange should now set their red portal onto the small raise platform ahead. Next, Blue will need to head back down and use the jump pad to speed through Orange's portals.

Once in the air, fire the purple portal at the wall ahead to land on the bridge. Move forward and onto the small ledge on the right. From here, fire at the wall to the right to bring the bridge to the exit. Orange should move their portal to its previous location and use the jump pad to reach the bridge. Travel through Blue's portals to complete the area.

Blue should Place their purple portal above the jump pad and the blue portal at the end of the light bridge. Enter the jump pad, move to the end of the light bridge and place a blue portal on the incline passed the grill. Orange should use the jump pad to sail through the air and land passed the second grill. Place your red portal on the incline ahead.

Blue should first move their purple portal at the end of the bridge and place their blue portal on the wall directly under the second grill. This will allow Orange to drop down, move through Blue's portals, and reach the hard light bridge source. Blue should now move their blue portal near the entrance so both players can return. Now, Orange should place their orange portal above the jump pad, let Blue enter first, and then travel through second to reach the exit.

Floor 6

You'll need to use the hard light bridges to protect you from turret fire. First, Blue should set one portal at the end of the light bridge and a second on the right wall to block the turrets. Orange should place portals beyond the light bridge so both characters can get by. In the next area, Blue should fire off their portal to block one side of the turrets. Next, orange should place one portal at the end of Blue's bridge source, and another portal on the adjacent wall to block the second set of turrets. Move through the gat ahead to reach the next room.

Blue should start this puzzle by shooting their purple portal at the end of the light bridge below. Drop down, turn right, and place a portal on the above right to create a bridge to the switch and exit. Orange should now head through Blue's portal and set one portal next to the bridge and the other at the second light bridge up high. This will create a barrier that will block the turret's sights. Move out to the switch platform, lower the barrier to hit the switch, and quickly turn the barrier back on. Grab the sphere that drops and take it to the exit door to finish the floor.

Floor 7

Orange should place their red portal at the end of the light bridge and the orange portal on the wall ahead to block the turret's laser. Now, Blue should place one portal near the same wall in front and another at the top level near the jump pad. Orange should quickly place their portal higher to protect Blue from enemy fire. Now this it safe, Blue should place one portal above the jump pad and the other on the incline to the right. Use the jump pad to destroy the turret and approach the exit. Orange should head through Blue's portals to reach the next area.

When ready, Orange should place one portal at the end of the light bridge and another place on the wall ahead to block both of the turrets. With the area safe, stand on the weighted switch to lower a platform ahead. Blue should now place one portal on the newly revealed wall and a second on the wall to the left. Travel through the portals and land on a small island.

Shoot the purple portal on the target bull's eye to the right and the blue portal on the wall just to the left of target. Press the button in this area to expel garbage and destroy one turret. If your blue portal was misplaced, readjust it before hitting the button to destroy the other turret. Now place your blue back on the overhead wall again.

Press the button a third time to launch a cube over to Orange. Orange should take the cube and set it on the switch they were just on top of. Blue will next need to re-apply their portals (One of them will have disappeared when Orange walked off the switch) to allow both players to meet up. Move through the grill ahead to end the floor.

Floor 8

Blue should pass through the grill and take the sphere that spits out. Next, Orange should place one portal through the grate behind Blue, and the other on any nearby by wall. Blue can look up and hand the sphere to Orange through the portals. Place the sphere in the node to block off the laser and move on.

In the next area Blue should place their purple portal at the end of the light bridge and the blue portal ceiling on their side of the grill. Orange should pass the grill and place one portal on the incline and the other on the ceiling. When the flying orb smacks into the light bridge, Blue should place their blue portal on the incline. This will cause the sphere to pass through Orange's portals and roll around the bridge. Grab the sphere and take it to the door and open it.

For this next puzzle Orange should set their first portal at the end of the light bridge and their second on the high wall on the left. Both players should enter the portal to reach the top of the light bridge. Blue should fire their portals at both panels marked with a "1", one inclined and the other on the ground. Orange should do the same with the panels marked with "2"; however you must act quickly as this will disrupt the light bridge. If timed right, Orange and Blue will smack into each other, leading to the next room. Take the disc here and place it in the drive to finish the chamber.

Excursion Funnels

Floor 1

Orange should put their first portals at the end of the funnel and the second on the white wall on the right. Blue should jump into the funnel and ride it to the other side. Here, place one portal on the wall on the left and the other straight ahead. Float to the other side and press against the button. Orange should follow to Blue's position, but drop down on the platforms that have now appeared. Head into the door, turn backwards, and fire your portal to whisk both players to the exit.

Floor 2

Orange will want to place their portals at the end of the funnel and the other on the wall on the right so that the funnel passes through the grill on the left. Blue will now need to use the jump pad to enter the funnel and into the grill. While still floating inside, place your purple portal on the hanging wall to the left and then fire the blue portal at the end of the funnel source (Overwriting Orange's old portal).

Orange should now put their red portal on the other side of the wall that contains the purple portal. Stand on the button on the ground, opening a window above, and place your orange portal at the end of the funnel from the blue portal. Blue should now hit their switch and place the dropped sphere into the stream. Orange should wait until the sphere hits the laser beam, and then fire their orange portal at the funnel source. This will keep the sphere in place, unlocking the gate to the exit elevator.

Floor 3

Blue will want to place one portal at the funnel source and the other at the lone white floor on the button. Afterwards climb inside the funnel and float upward. Orange should stand on the button and shoot one portal on the wall on the left. Now at the same time Blue will need to fire a portal at the incline while Orange shoots their other portal at the funnel source. This will cause Blue to fall, fly through the air, and land in the tunnel to the exit. Pick up the cube where and drop it down to Orange.

The other player should place the weighted cube on the button and complete the previous puzzle a second time. Because of your positioning, Orange may have to place their first portal on the funnel generator instead of on the left wall, but otherwise the solution remains the same. Once both players unit again, head to the exit.

Floor 4

Blue should place their blue portal at the end of the light source and their purple portal on the tiled section of the white wall on the right. Orange should place their first portal at the end of the purple portal, and one left of the room overhead. Take the jump pad to enter the portals and arrive at the room with the cube switch. Hit the button to drop a reflection cube into the stream that will arrive in the room.

Now, Blue should place their purple portal on the far right hand wall and take the jump pad to enter it. After riding the beam as far as it can go, place your purple portal on the left wall to enter the exit room. Now, Orange should place their orange portal on the wall in their room and shine the laser directly into this opening. Once it's in place, drop down and into the funnel source and ride Blue's portals to the exit room. From here place your red portal on the lone wall to transfer the laser into the node, opening the exit path.

Floor 5

Orange should place their portals at the end of the light source and the other on the wall on the right. Hit the jump pad and ride the beam to the weighted cube. Grab the cube and get back in the funnel. Now, Blue should stand on the button and reverse the flow of the funnel. Once Orange arrives at the funnel source, fire one portal above the entrance and the other one at the end of the source. Next, move off the button and allow Orange to float through the portal. Orange simply needs to drop the cube into the stream to unlock the floor's exit.

Floor 6

Orange should set their portals at the end of the grill and the light funnel source. Blue should now ride the horizontal funnel and jump into the vertical funnel when they intersect. Now put one portal inside the funnel source and the wall on the right. This will take you to the exit area and a switch to change the flow. Stand on the button and place a portal on the other end of the crusher. Orange should now ride the funnels and once again enter the vertical one that intersects. Place your orange portal at the same places as the old Blue ones to reach the exit.

Floor 7

Blue should enter the grill and fire one portal through the wall near the light funnel and the other one the only wall ahead. Orange should use the jump pad to land on the other side of the room. Turn around; shoot one portal at the wall ahead and the floor on the small island. Take the second jump to float into the tunnel's stream. Now, Blue will need to stand on the switch and reverse the flow, allowing Orange to land on the switch on the right side of the room. Once here, place a portal on the newly opened wall, but keep the other one on the floor.

Now, Blue can exit through the grill and take the jump pad, riding through Orange's portals to land on the top exit. To help Orange escape, Blue should set portals to allow Orange to return to the small island on the left with a floor portal. Once their, Blue can swing around to the left and place a portal at the funnel source. Now place your other portal under Orange to reach the exit.

Floor 8

Orange should place both portals on the left wall so that the funnel fires passed the grill and into the maze. Blue should now ride the funnel into the maze and place their purple portal on the wall, now put the blue portal on the ground and ride to the top. Blue should shoot their blue portal ahead and Orange will want to stand on the switch, which will move Blue forward. Now, Blue will need to drop and place their portal behind themselves; at the same time Orange will need to work the switch to help Blue avoid being crushed.

In the last maze area Blue will need to fire their portal below while Orange works the switch to keep them safe from crushers. Now Blue must fire their blue portal at the wall ahead while Orange stands on the switch to move to the weighted cube's location. There is also a turret here, so throw down a portal with the funnel to destroy it.

Now pick up the cube and ride the turn back to the exit (Your journey will have turned off the grill). Once the robots are re-united, Orange should place one portal on the incline and the second on the floor below. Each player should leap through Orange's portals one at a time to finish the stage.

Floor 9

Orange should place their red portal at the end of the light bridge and their orange portal at the other side to block the turrets. Blue will now want to place their purple portal at the end of the funnel, head down the passage and turn left where a white wall sits. Place your blue portal here and both players should ride off. Orange will want to move their orange portal to block the turrets to the side, while Blue moves the funnel to guide the players to the exit. As long as the light bridge blocks the turret fire, you'll enter through a grill to the exit.

In the next room Orange will want to place their red portal at the end of the light bridge and their second in front the turrets. Blue should look very fat up and put their purple portal at the end of the funnel, with their blue portal on the checkered floor. Orange should enter the funnel first, followed by Blue. Orange should move the light bridge to continual block off turret fire. Once reaching the top, Blue should look towards the chasm and place their blue portal at the wall on the far left. Now both players can jump into the stream and ride through the purple portal other end. Place one last blue portal on the cat walk to the right and ride the beam to the room exit.

Look out the window on the left to grab both the bridge and funnel again. Block off the first row of turrets and place the funnel to jet across the chasm. Now, switch the bridge so that it blocks the turret conveyor, which in turn will destroy any produced enemies. Place the funnel on the wall to the right to drop and enter the control room. Last, grab the disc and place it into the drive to complete the chamber.

Portal 2 is a great game. The levels were hard enough that I couldn't figure them out straight away, but could still noticed the solution after 5-10 minutes. Games like Modern Warfare 3 couldn't hold a candle.

Such a great game, the level design shows Valve's creativity. I wish companies like Infinity Ward would take a few hints while making mw3 and its levels. Modern Warfare 3 could use Valve's "touch", just look how great this and Team Fortress 2 is.

@ icepop4who: If it's so easy and you don't need a guide, what are you doing here? Hmmmm.... Kind of strikes me as an 'I'm better than you guys statement to me'. The truth seems to be, I got stuck somewhere and needed a little nudge in the right direction.

I love this phreaking game. Right when I thought it was going to end, it keeps on going! I thought it was more of Portal 1, then it goes nuts! The levels are organic, believable and atmospheric. Look out for my review. Incredible game.

What kind of idiot would actually use a Portal walkthrough? Solving puzzles is literally the only thing to do in this game. It's like paying money to have to read and follow a guide.

Without photos can be as frustrating to understand as some parts of the game. Try the youtube hints if you are really stuck.

If you liked the first Portal, you will love this one.. it has a good story and about 7hours of pure puzzel thinking. Some stages where way to easy and some took me a while to figure out. I also loved the twists of the game. To all of you that have played the game i only say "Im in space!" It was great fun.. Thinking of buying the game for ps3 aswell..

@Maxxramman ... *gag* there are three words I bet no one on this planet EVER expected to hear in a sentence: "amazing" and "will ferrell." WOW! I'm intrigued by how stupid parts of this game make me feel at times. To help with that I went and bought the first one. STILL have no idea how or why i'm blasting holes in walls just to be tested by this badly auto-tuned android! HOPEFULLY there will be sometime soon in the game where the greater meaning is revealed (I'd settle for the point ; ) Its also a little strange that the character you are supposedly playing as is a female. Hmmm maybe this is how a female feels if she chooses to play a FPS, i.e. CoD. Interesting.

@Kos1c & @XsickGamerX10 - It's more than just a puzzle game. It has a great story behind it and it ties itself with the Half Life Universe. I think it's a great game. It's better to have played the first one before playing the second.

@XsickGamerX10 I didn't know much about this game, and i got it yesterday. The game is a huge puzzle game, it's great fun, just sadly it's not as long. I've already completed it, took about 4-6 hours to do. But still one of those titles worth checking out. An easy 9/10 for me.

@bigkahunabuger portal 2 does not have a singleplayer section...only a game mode you can play by yourself...that shows gamestpot doesn't have a clue about games.

I would really discourage the use of a walkthrough for Portal 2. Its charm comes (at least partly) from the satisfaction of solving the puzzles, and being told what to do diminishes your experience of the game. I guess using one section if you're really, REALLY, stuck would be okay, but please go back and be sure that you need the help before seeking help.

I have Portal 2 and in my opionion it is to easy, I completed it in 7 Hours. The puzzles are good enought but there is only 1 way to solve a puzzle and it is easy to find the solution. The Story is realy great it has some realy good twists in it.
