  2. Grunt Birthday Party skull

    Effect: Headshots on grunts cause heads to explode with confetti.

    Where to find: Crow's Nest

    How to find: Right after the first objective, while en route to the barracks, you will fall down onto a pipe. At the end of this pipe, look over the edge to see a small space a few feet below you. You must simply drop over and as quicly as you can, pull back to land under the floor you were just on. After that, the skull will be at the end.

  3. Black-Eye Skull

    Effect: Melee hits instantly recharges your shield.

    Where to find: Crow's Nest

    How to find: As soon as you start the level, head straight up to the higher level. Head toward the door with the red light, then turn around. Jump onto the racks, onto the red metal light holders, then onto the ventilation tube. The skull will spawn at the end.

  4. Blind Skull

    Description: "Shoot from the hip"

    Stage: First Stage

    How To Find: When you get to the area where you see the Phantom overhead (one of the marines will point it out) jump over the rocks and keep following the path on the right. When you get to the cliff there will be a rock over of the side. The skull is on the end of the rock.

    Note: This skull has to be Activated before you start a Campaign map.

  5. Iron Skull

    Effect: When either player dies in Co-Op on any difficulty both players will restart at last check point or in single player if you die you restart the level.

    Where to Find: Sierra 117

    How to find: In the area where you rescue Sarge, behind the prison cell is a large ledge. Got to the far right side and jump on the boxes, then onto the pipes to get up on the ledge, goto the far end of the ledge, turning two corners the skull is at the far end.

  6. Tough Luck Skull

    Effect: Enemies do saving throws

    Where to find: Tsavo Highway

    On Tsavo Highway, about halfway through the mission (right after you are forced to walk through a large blue barrier), you will come out of a tunnel on the highway, and see a large pipeline on your left. Drop down in between the two, and run to the wall in front of you. Follow the wall all the way to where it connects with the cliff on your right, and turn to the left. There should be a few ledges--simply crouch jump from ledge to ledge, and the last one should have the "Tough Luck" skull on it.

  7. Mythic Skull

    Effect: Every enemy on the field now has double their normal amount of health.

    Where to find: Halo

    How to find: As soon as the mission starts walk up the hill in front of you and into the cave. Hug the right side of the cave and after a large boulder you will see a path on your right, just take the short path and it will be at the end.

  8. Cowbell Skull

    Effect: Explosive force increased (sputnik from H2)

    Level: The Ark

    Location: First pick up a grav lift from the small building near where you fight the scarab. Now proceed through the level until you reach the second sloping hallway (stairway), you should see some partitioned risers (platforms) halfway down. The skull is on the top level. Toss the grav-lift on the right side of the hall so it lands on the fourth little green dot from the door. Then run, jump, and use the grav-lift to propel you to the top. You should reach a ckeckpoint just as you enter the room so it you miss just try again.

  9. Thunderstorm Skull

    Mission: The Covenant

    Effect: "Field promotions for everyone!" -- Upgrades enemies to their stronger versions.

    After you shut down tower 1 and get access to the hornet, fly to tower 2 (the one the arbiter shut down). While walking up the stairs, go to the middle part that connects both and there should be a stair leading up to a platform where the skull is.

  10. The 7 Terminals

    The Ark:

    1. Start the mission and once you enter the first building take a left into another door and now you should be in a curved corridor. On the inside is a Terminal.
    2. After activating the bridge to let your comrades accross the gap, do a 180 and you should see it. (it does not open until you activate the bridge)
    3. In the third building after defeating the scarab, kill the group of sleeping covenant, then follow the corridor downwards. Once you reach a door in front that is locked, immediately on the left there's an open door. Go through and walk straight off, then do a 180 to find a secret room. It is in there.

    The Covenant:

    1. When in the first tower standing on the lift, face the access panel and turn left. Jump over and it's right there.
    2. Land your hornet on the second tower, walk towards the entrance but when you see the locked door, do a 180. Should be right in front of you.
    3. When in the third tower standing on the lift, face the access panel and turn right. Jump over and it's right there.

    Halo:

    1. After reaching the end of the first cave, hug the right wall and you will see a building. Jump up onto the walkway and hang a left once inside. It's right there.

  11. Fog Skull

    Mission: Floodgate

    Effect: "You’ll miss those eyes in the back of your head." -- Your motion sensor disappears.

    As you are walking down from the anti-air gun you destroyed in the previous mission, you encounter a ramp (next to a missile launcher). Around this ramp, you hit a checkpoint. At this point, you should also hear a marine yelling, “There! Over There!”. Look up and to the right, directly at the roof of the building next to the missle launcher. There is a single flood form (not to be mistaken with the two other flood forms jumping in front of you) which is holding the skull. Kill him before he jumps, and he will drop the skull down to the ground where you can retrieve it. Too early, and the skull will get stuck on the roof though, so just time it carefully.

  12. Famine Skull

    Mission: The Ark

    Effect: "Trust us. Bring a magazine." -- Dropped weapons will have very little ammo compared to normal.

    When you first go into the valley to the right after the wrecked phantom, look to your left where you will see a huge boulder. Use a ghost and get to the side of the boulder that is closest to the bridge overhead. It is easy to pilot the ghost up the side of the wall using the thrust. To get the skull, pilot 2 ghosts up the wall to the top of the bridge and stack them one on top of another next to the beam where the skull is placed. Simply jump from the top of the ghosts towards the skull and land on the beam.

  13. Tilt Skull

    Mission: Cortana

    Effect: "What was once resistant is now immunity" -- Enemies have different body parts that may be resistance to certain bullet types

    When in the circular type room with all the flood look for a small structure piece next to two archways, jump on top if it and up on the rocks to the top left, turn left and jump up again, then do a 180 and jump to the rocks across from you. After that follow the the rock sticking out and leading up on top of of the original circular room, the skull will be in a pile of blood.

  14. IWHBYD Skull

    Mission: The Covenant

    Effect: "But the dog beat me over the fence" - Unlocks bonus dialogue throughout the game. For most, this is the last skull, so this gives you the Hayabusa Helmet as well.

    To get this, get to the room where you "fight" the Prophet of Truth. Let the Arbiter kill him, turn around, and kill all the Flood here as well; makes it a LOT easier. With all obstacles out of the way, you need to jump through the Halo holograms here in a specific order, listed below:

    4 6 5 4 5 3 4

    When you jump through the final hologram, they all light up in a sequential pattern. The Skull will be at the end waiting for you right before the energy bridge leading to Truth's corpse.

  15. Catch Skull

    Effect: all enemies have 2 grenades, throw more grenades

    Level: The Storm

    Location: From the start, go through until you go outside again. When you go outside look straight across there is a small round building straight out there, the skull is on top. In order to get up there you can either use a warthog as a platform or grenade-jump. DO NOT destroy the wraith near the door or the skull will disappear.

  16. Orbital Skull

    Load up Orbital in forge mode, find the open area (the place with the two traffic cones and a pit you can fall down). In monitor mode (press up on the d-pad), fly all the way to the top and the skull is lying on a vent in one of the corners.

  17. Assembly Skull

    Load up Assembly in forge mode and go into monitor mode (press up on the d-pad). There are two "arms" attatched to the centre building. In monitor mode, fly up and into the small opening at the top of the arm (it's one of the two).

  18. Sandbox Skull

    In Sandbox, fly to the heighest possible point in the map. Look around till you can see the sun (not the "red light" on one side of the map) on the horizon, inbetween two Guardian towers. Turn right and face inbetween the next pair of Guardian towers (so the tower on the right of the sun is now the tower on the left). The skull is located outside of the map in this direction. If you are having trouble spotting it, try and use the zoom of a sniper rifle or beam rifle. There are several methods of obtaining the skull. You can use bubble shields, tube pieces and shield doors to form a tunnel, or you may fly over the skull and drop a teleporter exit so you can teleport to it directly. There are also several maps you can download on fileshare to gain easy access to the skull.

  19. Longshore Skull

    In forge mode, look for a red sign with a fish on it. It says "Fronks". Fly right up to it in monitor mode, then turn right. You should find an air vent. Fly over to it, and the skull should be at the bottom. Go higher then turn back into your character whilst holding the RB button to grab the skull on your fall down to the ground. Alternatively, use items as platforms to reach it.

  20. Heretic Skull

    In forge mode, fly to the top of the room in monitor mode. Go the platform with the sword on it. It’s shaped like a letter c or pacman. Turn right and fly over to the open room. Place a grav lift just before you enter it and jump, the skull is on a ledge just above the doorway, just in front of some vents.

  21. Citadel Skull

    In forge mode, fly around the map until you find the corridor with the overshield powerup (red). Go to the right side of the power-up (facing the power-up from the middle of the map) and stop just past the doorway. Turn around to face the power-up and stack up items (red and blue crates work best, usually about 3 or 4). Jump on top of the items and you should be able to grab the skull if you jump into the missing space on the ceiling.
