Portal 2 Walkthrough

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.
