Bandana skull
Level: The Silent Cartographer
Location: At the end of the tunnel on the ceiling in the Security console building (Warning: Grenade jump necessary.)

Malfunction skull

Effect: When activated, one random part of the Heads-up display will disappear after every respawn.[1]
Recession skull
Level: 343 Guilty Spark
Location: Locate to the left of the Facility in a little drop behind a shade turret. When you cross the fallen tree, you'll see a shade turret blow up and assault rifle fire coming from the structure. Instead of going inside, immediately go to the left and keep against the back wall. you'll come to a turret with a small drop behind it. Slide down the drop carefully and the skull will be waiting for you at the bottom.
Effect: When activated, every shot the player fires would deplete two rounds instead of one. For plasma-based weapons, the depletion rate is doubled.[3]
Black Eye skull
Level: The Library
Location: In the back of one of the vents before entering the Index chamber for the first time. (Warning: Grenade jump necessary.) Effect: Shields don't recharge on their own. Using melee on an enemy will recharge them. Description: On the first floor at the beginning of the level, you will notice squarish openings in the ceiling that the flood use to enter the level. Before entering the round, yellow room, find the vent closest to that door and do a grenade jump into it. The skull will be waiting for you.
Location Hint: So many shafts, so little time. This skull is hidden at the back of one of the vents just before you enter the Index Room for the first time. Use a grenade jump to get inside.
Effect: When activated, the only way players are able to recharge their energy shields after taking damage is to melee an enemy.[2]
Eye Patch skull
Level: The Library
Location Hint: The Index hides more than just the solution to the Flood. Look behind the Index when you reach it in the very last room of the mission. Avoid the Index and carefully jump around the edge of the room.
Effect: When activated, auto-aim will be disabled.[2]
List of Silver Skulls
Boom skull

Effect: When activated, all explosions' damage radius will increase two-fold.[3]
Piñata skull
