Skulls:
You can only claim/collect the skulls under the Normal, Heroic or Legendary difficulty settings. You must start from the beginning of the mission. You will not be able to see the skulls if you load from a checkpoint. In Co-op mode, as soon as one player picks the skull up, all players will receive the achievement. Not all skulls earn an achievement; only nine of them do so. To use skulls, press X at the lobby screen. This will give you a bonus multiplier for co-op and go towards earning the Guerrilla, Demon, etc. achievements.

Black Eye Skull: From the start of the "Crow's Nest" mission, without moving anything, you can see a massive pipe above you. Walk up the stairs, then up the next set. Turn to your left and jump up on the shelf unit. From there, jump to the red cross beam then up onto the pipe. From there, just walk to the end. Walk over the Black Eye Skull to claim it. You do not have to pick this skull up, it does it automatically. Its description reads "Bash your way to better health." Your shield will not auto-recharge anymore, and you must kill an enemy with a melee attack.

Blind Skull: In the "Sierra 117" mission, get to the area where you see the Phantom overhead. A Marine will point it out. Jump over the rocks and follow the path on the right. When you reach the cliff, there will be a rock over the side. The skull is at the end of the rock. Its description reads "Shoot from the hip". This skull must be activated before you start a Campaign map.

Catch Skull: In "The Storm" mission, do a grenade jump off a Warthog; or get a Ghost and go back to the ramp from which you first appeared. Use the Ghost to push a big square crate over to the front of the silo pod that has the skull. Jump from the box to reach the skull. Its description reads "Pull pin. Count to three. Throw." All NPCs will have two grenades and will throw them frequently.

Cowbell Skull: In "The Ark" mission, get a grav lift from the small building near where you fought the Scarab. Continue through the mission until you reach the second sloping hallway (stairway). Find the partitioned risers (platforms) halfway down. The skull is on the top level. Throw the grav-lift on the right side of the hall so that it ends up on the fourth small green dot from the door. Get a running jump and use the grav-lift to boost you to the top. You will get a checkpoint when you enter the room. Using this skull will increase explosive force, similarly to the Sputnik Skull from Halo 2.

Famine Skull: In "The Ark" mission, enter the valley to the right after the wrecked Phantom. Look to the left to find a large boulder. Use a Ghost to reach the side of the boulder that is closest to the bridge overhead. Get the Ghost up the side of the wall by using the thrust. Get two Ghosts up the wall to the top of the bridge. Stack them on top of each other next to the beam where the skull is located. Then, jump from the top of the Ghosts towards the skull and land on the beam. Its description reads "Trust us. Bring a magazine." Dropped weapons will have less ammunition.

Fog Skull: In the "Floodgate" mission, while you are walking down from the anti-air gun destroyed in the last mission, you will see a ramp next to a missile launcher. Near this ramp is a checkpoint. After reaching it, you will hear a Marine yell, "There! Over there!". Look up and to the right at the roof of the building next to the missile launcher. There is a lone Flood that is holding the skull. Kill him before he jumps. He will drop the skull on the ground. Note: If you shoot too early the skull will get stuck on the roof. Its description reads "You'll miss those eyes in the back of your head." You will no longer have a motion sensor.

Grunt Birthday Party Skull: Immediately after the first objective of the "Crow's Nest" mission, while en route to the barracks you will fall down to a pipe. Get to the end that pipe. Look over the edge to find a small space a few feet below. Drop over then quickly pull back to land under the floor you dropped from. The skull will be at the end of this area. When this skull is active, headshots will cause enemies to explode.

Iron Skull: After freeing Johnson and killing all the Covenant that come in the Phantoms in the "Sierra 117" mission, walk to the Pelican that arrives to pick you up. Face the cargo bay, but instead of hopping in turn left and follow the path. Once you hit the wall, jump up to your right to eventually reach a walkway. Walk all the way to the end. Take a left, then a right. At the end of this a little bit to the right is a dark corner. Press Up to turn your light on and you should see the skull. If you cannot see it you are probably standing on it. Its description reads "Death carries a heavy price...". Instead of only losing 25 points when you die, you will lose 75.

Mythic Skull: Follow the normal path in the "Halo" mission until you reach a cave. Hug the right wall until it branches off into a small path. At the end of this path is some rubble, and in front is the skull. Its description reads "Coverage under the Covenant health plan." It gives a 3x score multiplier for all kills.

Thunderstorm Skull: In "The Covenant" mission, shut down Tower 1 and get access to the Hornet. Fly to Tower 2 (which is the one that the Arbiter shut down). Go up the stairs. Go to the middle part that connects both. There should be a stairway that leads up to a platform where the skull is found. Its description reads "Field promotions for everyone!" Enemies will be stronger.

Tilt Skull: In the "Cortana" mission, enter the circular type room with all the Flood. Look for a small structural piece next to two archways. Jump on top if it then go up on the rocks to the top left. Turn to the left and jump up again. Turn 180 degrees and jump to the rocks across from you. Then, follow the rock that is sticking out and leads up on top of the original circular room. The skull can be found in a pool of blood. Its description reads "What was once resistant is now immunity." Enemies now have different body parts that may be resistant to certain ammunition.

Tough Luck Skull: Once you get past the part of the map after you are forced to leave your vehicles, you will go through a tunnel out onto an open "freeway". Immediately coming out of the tunnel you will see a huge pipe with two yellow ladders. Climb the second ladder. You should see a Regenerator power-up. Proceed to your right onto a small platform ledge where the yellow chain link fence is located. Jump onto that ledge, crossing over the fence. Directly behind you should be a large column that is holding up the giant pipe you were just on. Below that is a walkway. Fall off the ledge onto the walkway. Walk to the end of that. You should see a hidden ledge with the "Tough Luck" skull on it. A few attempts may be requires to jump across. Its description reads "Your foes always make every saving throw".

Terminals:

Start "The Ark" mission. After entering the first building take a left into another door. You will be in a curved corridor. On the inside is a Terminal.

After activating the bridge in "The Ark" mission to let your friends cross the gap, turn 180 degrees to find the Terminal. Note: It does not open until you activate the bridge/

In the third building after defeating the Scarab in "The Ark" mission, kill the group of sleeping Covenant. Follow the corridor down. You will reach a door in front that is locked. Immediately on the left is an open door. Go through and walk straight off. Turn 180 degrees to find a secret room with the Terminal.

Enter the first tower standing on the lift in "The Covenant" mission. Face the access panel and turn left. Jump over to find the Terminal.

Land your Hornet on the second tower in "The Covenant" mission. Walk towards the entrance. When you see the locked door, turn 180 degrees to find the Terminal.

When in the third tower standing on the lift in "The Covenant" mission, face the access panel then turn right. Jump over to find the Terminal.

After reaching the end of the first cave in the "Halo" mission, hug the right wall. You will see a building. Jump up onto the walkway and turn to the left once you are inside to find the Terminal.

Alternate ending:
Complete the final mission under the Legendary difficulty setting.

Sierra 117: Monkeys with teddy bear:
After you come into contact with the snipers in the woods, follow along the left rock path. You will find a strange family of monkeys holding a teddy bear.

Smarter respawning:
When playing in Co-op under the Legendary difficulty setting, it is best to have one player keep their distance from the enemy at all times. By doing this, if the rest of the players die they will respawn around the player that is farther back, rather than having to restart the checkpoint.
