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, unless doing so after you die. 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, go to where the first anti-air Wraith tank is located. In the that area, on the ground on the far side from where you enter, is a large gray cylinder. Take a vehicle and push a large crate to the side of it. Jump on the crate, then the silo. The skull is on the top of the silo. When activated, all enemies and allies will have two grenades and throw them often. This will also lead to the Covenant sticking themselves.

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. This skull, when activated, makes Grunts explode in confetti when they are headshot. There will also be some cheering, like a birthday party.

IWHBYD Skull: Go to the last tower. Before you get to the Prophet of Truth, there are a series of bridges with Halos. Do not jump through any yet. First, kill the Prophet and clear the bridges of enemies. Then jump through the Halos in this order, with "1" being the entrance and "7" being the end near where the Prophet was located: 4, 6, 5, 4, 5, 3, 4. Note: You can also use the longer sequence of 4, 5, 6, 5, 7, 6, 5, 4, 1, 2, 3, 2, 7, 2, 1, 3, 4, 6, 7, 5, 4, 5, 3, 4. This is much easier in Co-op mode with three or four people. This is the Halo theme if it was played on a phone by dialing the numbers. If done properly, the Halos will start flashing. If the Halos do not flash, revert to your last saved game. The skull is near the Prophet's ramp. Its description reads "But a dog beat him over the fence." This skull unlocks hidden dialogue when activated. If this is the thirteenth skull you have located, it will also unlock the Hayabusa Head. IWHBYD stands for "I Would Have Been Your Daddy" which is a level chapter from the original Halo.

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.

Katana:
Unlock all achievements and collect all skulls.

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

Hint: Crow's Nest: Red vs. Blue reference:
After your first encounter with the enemy and you destroy everything in the tunnel, go forward instead of making the turn where you would normally continue the level. At the end of the tunnel should be a man talking to someone behind a door. That person should sound like Church from the machinima based Red vs. Blue talking to Caboose about something.

Almost immediately after you begin the mission you will find a large roadway crawling with Covenant forces. You are supposed to fight your way to a door that will lead you to a room with two turbine-like objects. Instead of going through this door, follow the road all the way to the end. Make sure to kill all covenant on the way. Once you reach the end there will be a Marine knocking on a door wanting to get in. If you listen closely you can hear that it is actually an excerpt from Red vs. Blue where Simmons is talking to Griff trying to get into the base.

Hint: Crow's Nest: NBA Spartan:
At the beginning of the level, grab the skull on top of the large pipe near the ceiling before you pick up any weapons. This is easier in Co-op mode. Press RT repeatedly. This will cause Master Chief to drop the skull but because he has no weapons, he will immediately pick it back up, making it appear as though he is dribbling the skull like a basketball.

Hint: Isolation: Evil duck:
On the multi-player map Isolation, go to the Flood cave where the Ghost is located. Go in front of the Ghost, look up, and walk a short distance slowly. You will see a big smudge on its face, but look carefully for the duck's body. You can partly see its face and the horns on its head. This is related to the picture in Zanzibar in Halo 2.

Hint: Sandtrap: Flipped Elephant message:
This is best done with two players. Enter the Sandtrap on the Forge. Try to get as many pre-placed fusion coils and plasma batteries before you start. Place as many fusion coils and plasma batteries as possible in front of an Elephant and drive into the pile. Then, shoot into the pile until it explodes. It will either just jump a little, stand up on the rear, or turn all the way around. When you get close, the message "Press RT to... Wait. How did you do that?" will appear.

When in Sandtrap, get two Elephants to collide into each other. Have one flip the other over. When one is flipped over, instead of stating "Press X to flip Elephant", the message "Press X to... Wait...What... How did you do that?" will appear.

Hint: 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.

Hint: Defeating Flood:
When you kill any Flood that can come back to life by the infection forms, hit the body and it should break apart. This saves ammunition.

Hint: Destroying Wraiths:
To easily destroy a Wraith and save time and ammunition, go to the back side. Aim at the little circle in the back. With about five to ten shots it will be destroyed.

Hint: Service tag I17:
If you go to "Appearance" and try to change your service tag to I17 (Master Chief's number is 117) the game will not allow it. It says that the tag is reserved for use by the UNSC.

Hint: Getting in the same ranked Lone Wolves game:
Go to your Dashboard. Change your language to the second option from the bottom. Start Halo 3. Invite four other friends that are about the same rank as you. Also have them change their language to the same one as you. Get everyone in the same party before you want to get them in the same party. Everyone must search at the same time. Everyone then must make a game in Lone Wolves. Before you go to start the countdown, press X to change the search options to the bottom one, which is to search for the same language. If done correctly, chances are you will be in the same ranked Lone Wolves game as your friends. You can now get achievements or level someone up.

Hint: More grenades:
In multi-player or system link mode, when you kill someone slash their dead body with the Energy Sword. More grenades come out of it.

Hint: Very fast Spartan laser fire:
In Forge mode get a Spartan laser. Charge it until its almost about to fire. Before you fire, turn into the Monitor. Fly around until you get a target. Before you turn back into a human, hold RT to fire within at least half a second (if done correctly). You can use the Monitor's aimer to aim the laser.

Hint: 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.

Glitch: Living grenade:
Sticky grenade your monitor ally while he is human. Have him quickly change to Monitor The grenade will not detonate. Go near anyone and change back to human then back to monitor very fast. The grenade will detonate.

Glitch: Construct: Go under map:
To do this trick you must be in Forge mode and be at Construct. Make sure you sell a respawn point before doing this glitch. Start out as the Oracle. Go down the pink grav lift by using your boost (press LT). There should be a few holes. You cannot fit down these as the Oracle. Start boosting into one of these holes that is not a closed circle. The Oracle should go slightly lower into this hole. Make sure you keep holding boost then turn into the player (either Spartan or Elite). You should fall underneath the level. Make sure you drop a respawn maker on a place where you can stand. This is to allow you to back there whenever desired. To prove you are under the level try to fly up without going through the grav lift. There is an invisible wall just like in the Foundation level in Halo 2, except on the bottom. This may not work on the first attempt.

Glitch: Halo: Unlimited Spartan laser:
Use the following trick to get an unlimited Spartan laser on last level "Halo". Play through the level until you meet up with Sergeant Johnson. Shoot him until he falls down and drops the Spartan laser. Quickly pick it up and shoot it at him. Keep shooting him until he kills you. When you respawn, knock him down again and pick up his laser. He should get back up with another laser on his back. When he does, shoot him down again and pick up the new gun he drops. This laser should have unlimited Spartan ammunition. This makes it easier to destroy the Guilty Spark 343.

Hayabusa Armor
Collect the hidden skulls throughout the game to unlock the pieces of Hayabusa armor.
