Halo 3 skulls

Summary
A Skull in Halo 3 is an easter egg left in by Bungie to make the game more challenging or interesting, or to unlock potentials that would otherwise remain hidden. There is no information text to wield a skull, as there is with a weapon, but it can be picked up just the same, and its effects range from the useless to the terrifying. In Halo 2, these skulls were hidden very far out of the normal path of the level, sometimes even backwards. In Halo 3, it is the same old situation. In addition, the skulls now have some sort of importance to the Halo 3 Meta-game. They multiply the amount of points you receive in the meta-game, meaning that activating them in the lobby will give you point multipliers.

'''NOTE: In order to obtain any of the skulls, you cannot start the level from a mid-level "insertion point"—you MUST begin the level from the very beginning. You do not, however, have to finish the level after you hold the skull. You can save and quit after holding it, and it will be fully unlocked.'''

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, if you're facing Johnson. You can gain access to the roof by jumping onto the pipes. Travel all the way over to the left side of the roof, and the skull is concealed in the corner.

Difficulty: Normal, Heroic, Legendary

Achievement Icon: A skull marked with a stylized drawing of a hammer

Effect: When playing co-op, if either player dies the game restarts you at your last checkpoint, similar to Halo 2 on Legendary. On solo, it restarts the mission.

Point Multiplier: 3x

Black Eye
Level: Crow's Nest

Directions: It's in the same room you start in. Hanging down from the ceiling is some piping. On top of this piping, on the side nearest to the large display (the one that Hood appears on) lies the “Black Eye Skull”. You can gain access to the pipes a few different ways, one of the easiest however is to jump on the crate like thing, then jumping onto pipes from there.

Difficulty: Normal, Heroic, Legendary

Achievement Icon: Skull marked with a bruise under one eye.

Effect: Your shield does not charge normally. To charge your shields you must hit an enemy with a melee attack (anything but the Energy Sword).

Point Multiplier: 1.5x

Extra: At the screen where you can turn the skulls on, this skull has a black 'bag' under the left eye hence 'Black Eye'.

Tough Luck
Level: Tsavo Highway

Directions: At the point in the level when the huge covenant cruiser flies overhead (after the first shield blocking the road), on your left is some large piping following the road you are walking on. Underneath this piping are some support beams that extend out over a cliff. Jump onto the first of these beams, and travel to the end of it. Look to your left, and the Tough Luck Skull will be sitting on a rock extending from a cliff edge.

Difficulty: Normal, Heroic, Legendary

Achievement Icon: A skull marked with three clovers.

Effect: Enemies always make every chance to dodge and avoid your grenades.

Point Multiplier: 1.5x

Catch
Level: The Storm

Directions: In the first outdoor area with the two AA Wraiths, the skull is on top of the silo over by the ramp that leads to the next area of the level. Destroying the AA Wraiths will cause the skull to disappear. You can use a vehicle to get a boost to the top of the silo or jump on another player's head in Co-op.

Difficulty: Normal, Heroic, Legendary

Achievement Icon: Skull marked with a stylized drawing of a plasma grenade.

Effect: AI will toss more grenades.

Point Multiplier: 1.5x

Note: There is a glitch in some games where this skull will not appear.

Fog
Level: Floodgate

Directions: At the very beginning of the level, 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!” You have a small window of opportunity at this point, but it is fairly easy to get the Fog Skull. Look up, and to the right, directly at the roof of the building next to the missile launcher. There is a single flood combat 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. Also there are some sandbags in the way, don't miss the shot by getting stuck behind them.

Difficulty: Normal, Heroic, Legendary

Achievement Icon: A skull marked with a swirl of fog

Effect: No motion sensor

Point Multiplier: 1.5x

Famine
Level: The Ark

Directions: Near the point where the path you follow branches off into two sections (one leading to the area where you need to let the tanks across the bridge, and the other leading towards the area where you meet up with the frigate). Take the right path, as you would if you were completing the mission, and you’ll notice a structure above you / to the right of you (near the area that you pass 3 of the large support beams extending into the cliffs. Inside of the fourth support beam, lies the Famine Skull. A well placed grenade, a Brute Chopper, or deployable cover should have you up there in no time! You can do this before or after you get the Scorpion as you pass the area twice, the skull spawns there as sson as you reach that area the first time.

Difficulty: Normal, Heroic, Legendary

Achievement Icon: A skull marked with a smaller skull

Effect: When enemies drop their weapons, they drop less ammunition"

Point Multiplier: 2x

Thunderstorm
Level: The Covenant

Directions: After you take command of one of the Hornet vehicles, fly towards the first force field generator (the one the Arbiter disabled), and land. The skull is waiting at the very top, at the end of the ramp extending over the sea.

Difficulty: Normal, Heroic, Legendary

Achievement Icon: A skull marked with a lightning bolt

Effect: Each enemy receives a rank promotion, for example, Minor Grunts will become Major Grunts.

Point Multiplier: 1.5x

Tilt
Level: Cortana

Directions: In the circular room where Cortana mentions that she “Likes to play games too…” It’s a bit difficult to get to, as it requires getting on top of the ceiling of the room. Upon entering the room, head towards the left side where you will see some mushroom shaped extrusions along the wall. Get on top of these, and then look up and towards the right for another set of extrusions. Jump to these. From here, you should be able to jump on top of the ceiling of the room, where the Tilt Skull lies in the center.
 * Note: If you try to get the skull on your second time through the room (after you start the chain reaction) it wont be there.

Difficulty: Normal, Heroic, Legendary

Achievement Icon:

Effect: Enemy resistances and weaknesses are greatly increased. Essentially, it creates a situation where you will more often have to use a battery weapon to take down shields and power armor, and then an ammo weapon to finish the opponent off, than just use one or the other to take them down.

Point Multiplier: 2x

Mythic
Level: Halo

Directions: At the beginning of the level start by heading into the canyon, but hug the right wall. Very soon, you will notice that there is a turn to the right that is off the normal trail. Head a bit down this path, and the “Mythic Skull” will be sitting there.

Difficulty: Normal, Heroic, Legendary

Achievement Icon: Skull marked with a swirl

Effect: Enemies have 2x more health and shielding, and are therefore harder to kill.

Point Multiplier: 2x

Blind
Level: Sierra 117

Directions: Near the first enemy encounter stay to the right. Follow the wall on around past the small building until you reach the cliff edge. The skull is on a rock right just over the edge.

Difficulty: Normal, Heroic, Legendary

Achievement Icon: No Achievement

Effect: HUD and first person arm disappear.

Grunt Birthday Party
Level: Crow's Nest

Directions: After the first objective, en route to the barracks, you will fall down into a large pipe. There will be smaller pipes coming from the sides and Drones (insect-like enemies) flying out right and left. At the end don't fall off to the floor, look over the edge to see a small ledge a few feet below you. The ledge has a green arrow pointing towards the wall. Your goal is to just drop over the edge and immediately pull back and land under the floor you were just standing on, (on the ledge), or you can try to slide onto it from the edge. Once there, the skull will be at the end in a room. To pick it up you have to press and hold the Right Bumper.

Difficulty: Normal, Heroic, Legendary

Achievement Icon: No Achievement.

Effect: When killed by headshots, Grunts heads will explode into confetti, and children cheering will be heard.

Cowbell
Level: The Ark

Directions: Begin by heading all the way to the part of the level where you battle the Scarab. After defeating it, look in the middle of the desert area which you battled it in for a fairly large structure (it’s the building you see if you are at the bottom of the ramp you are supposed to go up, and turn to look in the opposite direction). Inside of this structure are several Gravity Lifts (shown below). Take one of these for later. Next, head up the huge ramp, and head inside of the building (the one with the cartographer inside). Pass through a few of the rooms in this building, and you’ll eventually come to a room with a whole lot of Explosive crates. Right after this room is a Staircase/Hallway that leads to the level below. The Skull is located at the top of the room, at the point where you turn on the staircase to head for the next part of the slope. There are four platforms above you, the Skull is on the uppermost of these platforms. Use the Gravity Lift to jump up to it (try to position the grav lift on the line above the second light spec up the ramp, and try try try again, reverting saves when you fail repeatadly. Alternately, try and get the Grav Lift so that it is half way on and then jump into the stream from below), and there you have it! -But if it's not there, you probably didn't make it to the top. Fall down and look up and you will see one more "level." An alternate method is to take one of the crates from the room before, roll it down the ramp up next to the platforms, and place the grav lift on top of the crate. This will get you just enough height to reach the top platform.

Difficulty: Normal, Heroic, Legendary

Achievement Icon: No Achievement

Effect: Explosive force increased

I Would Have Been Your Daddy
Level: The Covenant

Directions: After defeating the Scarabs and going inside, get to the location with all 7 Ring Holograms. Continue until after the cutscene where the Arbiter kills Truth and kill the Flood(make sure that the Flood music has stopped) before jumping through the ring holograms in a specific order. That order is as follows (1 is at the entrance, 7 is closest to Truth): Please note: If you activate any skulls, this will not be in your skull inventory.

4654534

When you jump through the final halo, the rings will start pulsating, and you will be awarded the “I Would Have Been Your Daddy” skull. It will be right next to the bridge that brings you over to the Prophet of Truth.

There are three different ways to find the IWHBYD skull, depending on the selected difficulty. The following sequence works on Normal difficulty - 4654534.

Difficulty: Normal, Heroic, Legendary

Achievement Icon: No Achievement

Effect: New Dialogue in Game
