Grunt Birthday Party


Level: Reunion

Icon: A skull marked with a candle.

Effect: If a Grunt is shot in the head with any headshot-capable weapon (such as the DMR, Beam Rifle, Carbine, Sniper Rifle or Magnum), a popping sound is heard, colorful confetti explodes out of it, and a sound clip of children cheering from the game Hurray!"can be heard in the background.

Fog


Level : Reunion

Icon: A skull marked with a swirl of fog.

Effect: Your Motion tracker is disabled completely.

Point Multiplier: 1.5x

Directions:

Tough Luck


Level: Evacuation

Icon: A skull marked with a three-leafed clover.

Effect: Enemies dodge Grenades, Needles, slow moving projectiles and vehicle assaults with a greater success rate.

Point Multiplier: 1.5x

Directions:
 * 1) Keep battling through to the point where you must fight a group of Brutes, two of which are using Choppers.

Catch


Level: The Storm

Icon: A skull marked with an image of a Plasma Grenade.

Effect: All AI-controlled units, friend or foe, throw grenades more often, where applicable. It even affects scripted grenades. For example, on the level Crow's Nest, on the part where the Warthog is hit by a Plasma Grenade, it will now be hit by two, three, or even four. The Catch Skull has no effect on Flood. It should be noted that characters will throw an unlimited amount of grenades at their enemies. The skull actually does seem to increase the number of Kamikaze Grunts. It has been observed that the Marines will sometimes throw grenades with reckless abandon, similar to their behavior in Halo: Combat Evolved.

Point Multiplier: 1.5x

Directions: There are multiple methods which can be used to get onto the building.
 * 1) If you have the Easy Shield in your service record, the skull will NOT spawn. You have to beat the campaign on normal or higher to make the skull spawn again.
 * 2) Battle through to Lakebed A -- the point where you fight an Anti-Air Wraith, a handful of Ghosts, and a standard Wraith.
 * 3) You should see a silo-like building (see image). On top of this is the skull. Look for the ramp that leads over to the platform where the normal Wraith is dropped.
 * 1) Hijack the Anti-Air Wraith and maneuver it so the back (the part with the plasma mortar, or in this case, fuel rod launchers) touches the base of the silo where the ground rises slightly; then, simply get out. The only problem is that this will cause an NPC Hornet to fire upon the standard Wraith, and the Wraith may focus its fire on you, so you will need to work a little quickly. The Anti-Air Wraith should remain still while you jump on the back and onto the top of the silo.
 * 2) Explosive Jump.
 * 3) Park a Ghost below, then jump from it onto the building. Use an Explosive Jump if necessary.
 * 4) Park one Ghost on the Wraith-side, then get another Ghost and park it on top. You should be able to simply jump on top of the Ghosts, then onto the silo.
 * 5) Take a Deployable Cover, then use it between the red wall and the building. Move out of the way and you can use the cover as a stepping stone.
 * 6) On Co-op, one player can jump onto the other player's head, then onto the building.
 * 7) Drive the Warthog at the foot of the silo and crouch-jump onto it. Make sure that the Warthog is at the Wraith-side of the silo before attempting the crouch-jump.
 * 8) Drive the Warthog between the silo and the wall so that it is turned on its side. Jump onto the red wall, then jump onto the silo.

Note: Do not destroy the standard Wraith, or the skull will disappear. Do not physically damage the normal Wraith (though the plasma turret operator can be sniped safely) in any way or the skull will disappear.

Famine


Level: The Ark

Icon: A skull marked with a smaller skull. The smaller skull seems to have a line between it and some dots (food). This describes the obvious traits of a famine.

Effect: All weapons that are dropped by enemies or are scripted to spawn on the ground (e.g., near a crashed Pelican or group of dead bodies) have halved or reduced ammunition or charge. However, weapons found in cases still have the standard amount of ammo.

Point Multiplier: 2x

Directions:
 * 1) After obtaining the Scorpion, you will be directed into a fork in the road. Going straight will lead you into a giant bowl-like valley, and going to the right will lead you through a broad sandy road.
 * 2) To the left is the bowl with two roads cut into the rock face. Go to the right and drive directly ahead until you hit the rock wall.
 * 3) When you get underneath the platform structure, you will notice some climbable rocks on the right that will lead you to the platform itself. You will notice several beam-like supports alongside the platform. Go to the very last one, at the end of the platform. If you jump up you can see the skull at the end. Align yourself right up to the support. You need to get to the crevice of it, sticking out and away from the platform; the skull can be seen in it. There are several methods to obtain this skull:
 * 4) Method A: Stick a Plasma Grenade right where the beam-like support and incline meet (on the bottom edge of the incline). Back up, run and jump, aiming a little higher than the skull. You should be just over and a little forward of the grenade when it explodes giving you enough of a boost to reach the skull.
 * 5) Method B: Pick up a Deployable Cover and place it in front of the pillar with the skull and use it as a step to the ledge. It may take a few tries to place it exactly at the perfect spot, as it may slide off and fall off the ledge.
 * 6) Method C: Play the game in Co-Op mode. Stand on your friend's head and have them run and jump towards the skull. At the highest point of their jump, jump over to the ledge. If performed correctly, you should land on the platform.
 * 7) Method D: Deploy a Bubble Shield so that the edge of it is near the edge of the structure. The Bubble Shield should keep the grenade you throw inside it so right after you throw, jump, and the grenade should give you a sufficient boost.
 * 8) Method E: Take a Brute Shot, and aim it downward but still on the building Take a leap, and as you jump, fire downward and you will be able to launch yourself to the skull.
 * 9) Method F: If you saved the Rocket Launcher from the downed Pelican, you can rocket jump by positioning yourself a suitable running distance from the platform with the skull, running at it backward, jumping as you reach the slanted floor and firing a rocket. The blast should be sufficient to propel you to the platform. It may take a few tries to get it without killing yourself, and is inadvisable on any difficulty other than Normal for this reason.
 * 10) Method G: Find a few Ghosts, and use the boulder and a boost+A-button combo to get them onto the platform. Then stack them near the spot with the skull and you should be able to jump from on top of them to the skull.
 * 11) Method H: On the way back through this canyon, after getting the Scorpions from the Forward Unto Dawn, as you pass under the arch and blow up the Phantom, there is a wall to the left of the part where the canyon narrows that you can drive a tank up. If you drive one up, then wedge it in the area where the Forerunner structure comes closest to the cliff you're on, you can take a second tank up the cliff, and drive it across the bridge made from the first one, onto the Forerunner structure, then, with some careful positioning, use its turret as a platform to jump to the skull

Tilt


Level: Cortana

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

Effect: All enemy weaknesses and resistances double. Example: Brute armor is twice as weak to plasma weapons and twice as strong against projectile weapons.

Point Multiplier: 2x

Directions:
 * 1) The skull is at the top of the large circular room where Cortana says "It was the coin's fault! I wanted to make you strong, keep you safe (drop in tone). I'm sorry, I can't..." When you enter this room you will fall out of a hole in the ceiling, next to a sitting, dead Elite. To the left of the room will be some small, somewhat fungal, growths on the walls. Near this is a rounded pillar.
 * 2) Stand on the pillar and jump to the thin growth outcrops to the left. On many of them, you will hit your head on an obstruction above if you are not careful; spoiling the jump. After the first two to the left, turn around and look away from the rock wall - then left ninety degrees for another one with a longish extrusion of Flood material.
 * 3) This one is difficult as your head will hit the wall with jumps from many of the obvious positions. One jump that works is at the tip of this jump, back about 2 feet from the edge, and jumping slightly left (approx one foot) of the tip of the target jump. Another jump that works is; When you get on the the upper outcrop on the left, facing the other outcrop you are jumping to, move as far as you can to the left. Then, jump toward the other outcrop with the extension of flood material. Walk up the extruded Flood tentacle onto the roof of the area where you will find the Skull in a small pile of blood and bones. Note that underneath the platform you usually walk on are two to three Deployable Covers near the Terminal with Cortana's message. These can be placed on the pillar and the ledge to make the jumps easier and help you avoid things that can cause your jumps to fail.

Mythic


Level: Halo

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

Effect: All of the Covenant you encounter have twice the amount of health and shields.

Point Multiplier: 2x

Directions:
 * 1) At the beginning of the level, move forward, hugging the right wall and curving slowly left in the cave up ahead. After a short amount of time, you will see a tunnel opening to the right. Move through this, but still hug the right wall. Part way along an opening (cave) on the right will open up.
 * 2) Move inside, turning your flashlight on (up on the D-pad of the controller). Soon you will reach a dead end, and the skull is on the ground, among the rocks.

Cowbell
Level: The Ark

Icon: A skull marked with a cowbell.

Effect: Physics impulses are increased. Explosions and melee attacks launch characters and objects farther, but the damage is not affected.

Directions:
 * 1) You must start this level from the beginning; starting from any other point will cause the skull to not appear. After defeating the Scarab, take a Gravity Lift from the small structure in the center (to the right of the entrance up the large slope), then continue on until you pass the room with a lot of explosive Plasma Batteries. In the hallway after this room, there is a tall section with openings above the turning point of the hall, and the skull is in the top one of the highest of these. There are several methods to obtain this skull:
 * 2) Method A: Use the Grav Lift to get there. The ideal place to deploy it is about three fourths of the way down the ramp, and a little to the left of the center, while facing up-ramp (facing up-ramp will ensure the Grav Lift doesn't slip farther down). Run down the ramp and jump, such that you reach the peak of your jump while directly over the Grav Lift. You should also be running towards the tall section, aiming towards the middle of the top shelf on the section. If your Grav Lift expires or is destroyed, you can always revert to last save since the room containing the skull is a checkpoint. If you have difficulty getting there, crouch while being Grav-Lifted. This may take a few tries.
 * 3) Method B: If you are having too much trouble placing the Grav Lift, it is possible to drive a Brute Chopper into the building. You can then drive the Chopper to the bottom of the ramp, jump onto it, and deploy the Grav Lift, which will go through the vehicle. You should be elevated to the opening with the skull.
 * 4) Method C: If you are playing on Co-Op, have two of the players grab a Grav Lift. One (Person A) should drop their Grav Lift before the platforms, use it to go up to the fourth level (one below the skull), and wait for their partner (Person B) to join them. Person B should stand right on the edge of that platform and deploy their Grav Lift while facing straight down. If Person A placed the first one right, then the two Grav Lifts should line up, with one hovering above the other. Person A should then walk backwards off the edge and onto the Grav Lift(s). A will end up being suspended above the platform with the skull, at which point they should just keep holding the left thumbstick forward until they move onto the platform. If they can't move forward, they should keep pushing forward anyway, because when the lower Grav Lift breaks, they will drop onto the platform.
 * 5) Method D: If you managed to pass through the previous room without setting off any of the plasma batteries, push one down to the edge of the openings, detonate it with a plasma grenade or a brute shot, and explosive jump to the top opening.

Trivia

 * Until one of Halo 5's updates you could not revive teammates nor be rivived when the Iron skull was turned on.
