Halo 3 skulls

Skulls are easter eggs in Halo 3 designed to make the game more challenging or interesting.

Background
The skulls resemble those in the multiplayer game variant "Oddball", and can be used as weapons in much the same way but they lack information text to pick them up. They are usually hidden out of the way, so one must search for them, or else know where they are, to get them.

Do note that in order to obtain any of the skulls, you have to begin the level from the beginning, on Normal or higher difficulty. In most cases, you do not have to finish the level after first picking up the skull, so can simply save and quit; nor do you need to carry the skull after picking it up. After you first pick the skull up, you merely need to press X at the level selection screen to select whether or not you want it, or any others, active.

"Gold Skulls" will grant you achievements when you first get them, but "Silver Skulls" will not. They are differentiated on the selection screen by their background, but are identical in-game. In the Campaign Scoring mode, activating gold skulls will grant you a multiplier to the points you receive, depending on the skull and/or skulls.

Iron
Level: Sierra 117

Directions: This skull is at the end of the level. It is located on the roof of the building to the left of the building where Sergeant Johnson is being held captive (facing the entrance). You can get up by jumping onto the pipes. Go all the way to the end of the rooftop, and the skull will be there.

Icon: A skull marked with a hammer.

Effect: If you die while playing solo, you will restart at the beginning of the level (you cannot revert to the last checkpoint at any time). If any player dies while playing co-operative, you will reset to the last checkpoint.

Point Multiplier: 3x

Black Eye
Level: Crow's Nest

Directions: find it yourself Icon: A skull marked with a smaller skull with a bruise under one eye. Also, the skull’s left eye is marked with a bruise underneath it.

Effect: Your personal energy shields no longer recharge normally. To do this you must melee an enemy with any weapon other than the Energy Sword.

Point Multiplier: 1.5x

Catch
Level: The Storm

Directions: In the outdoor area with an AA Wraith, some Ghosts, and later a normal Wraith, there is a silo-like building to the end of the cliff. Get up onto it (using a vehicle and a grenade or an ally), and the skull will be there. Note that if the non-AA Wraith's driver is killed (whether or not the Wraith is destroyed), the skull will disappear. This skull can be seen from several locations, including the boathouse where the sniper rifle is located and the landing where the regular Wraith is located. If the skull disappears, go back to your last saved checkpoint.

Note: There is a glitch in some games where this skull will not appear, even if the other instructions have been followed. In such an event, you should complete the entire campaign on at least Normal difficulty. Also note that the skull itself is affected by physics, so if a Wraith’s plasma mortar hits the top of the silo, the skull may be lost.

Icon: A skull marked with a diamond.

Effect: AI controlled units throw more grenades, where applicable.

Point Multiplier: 1.5x

Fog
Level: Floodgate

Directions: After playing through the level for a short while, you will hear a marine yell “There! Over There!” If you look up to the right, you will see a single Flood combat form (holding the skull). Shoot it before it jumps away, and the skull will be launched, so it may take several tries to have it land on the ground. Shooting too early will leave the skull on the rooftop.

Icon: A skull marked with a swirl of fog.

Effect: Your motion sensor is no longer visible.

Point Multiplier: 1.5x

Famine
Level: The Ark

Directions: Shortly before you reach the area where Johnson flies down and contacts Commander Miranda Keyes, you will notice a small fork, the other path leading to your future destination. Pass through here, and head to the end of the stretch with the platform overhead. At the end, turn right and you will see a boulder. Use it to climb onto the platform, and walk to the last of the supports going up. It has an opening over the slanting part of the platform, and the skull is in there. Use a grenade or deployable cover to get up. If you prefer, you can come back to here after getting the Scorpion and then get the skull.

Icon: A skull marked with a smaller skull.

Effect: All weapons that are dropped by enemies or are scripted to spawn on the ground (e.g., near a downed Pelican) have halved ammunition or charge.

Point Multiplier: 2x

Thunderstorm
Level: The Covenant

Directions: After you get into a Hornet for the first time, fly to the first tower you see to your right (the one the Elites disabled). The skull is on the top of the ramp that overlooks the ocean.

Icon: A skull marked with a lightning bolt.

Effect: All enemies are promoted to their next available rank, where applicable.

Point Multiplier: 1.5x

Tilt
Level: Cortana

Directions: The skull is at the top of the large circular room where Cortana asks your name, and says it’s very nice to meet you (your screen and movement don’t change for this one). To the left of the room will be some small, somewhat fungal, growths on the walls. Using these, jump up onto a platform. There will be some more nearby, so use those to get to a large circular platform with the skull on it. The skull will not be there after you retrieve Cortana.

Icon: A skull marked with a smaller skull with a hole in its head.

Effect: Enemy resistances are greatly increased. Where a particular type of weapon normally does slightly reduced damage (e.g., projectiles against Brute armor, or plasma against Brute flesh), it is instead greatly reduced.

Point Multiplier: 2x

Mythic
Level: Halo

Directions: Hug the right wall from the very beginning of the level. Soon you will reach a cave with a dead end, and the skull is on the ground, among the rocks.

Icon: A skull marked with a circle with a smaller circle in it.

Effect: The health of all enemies doubles.

Point Multiplier: 2x
