To get this, get to the room where you "fight" the Prophet of Truth. Let the Arbiter kill him, turn around, and kill all the Flood here as well; makes it a LOT easier. With all obstacles out of the way, you need to jump through the Halo holograms here in a specific order, listed below:

When you jump through the final hologram, they all light up in a sequential pattern. The Skull will be at the end waiting for you right before the energy bridge leading to Truth's corpse.

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.

• 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.

• Easter Eggs

There are many eggs on Halo but these are the ones I found myself:

(No.1) In foundry on forge spawn a container single, doesn't matter whether its open or not.Now go into human mode and look at the side that doesn't have the UNSC emblem on it, now look carefully, if you see something it will be in the center of the of that side.You will see either one or two things, a panther with paws up like he's going to attack you, or a little statue of Anubis one of the egyptian gods.

(No.2) This one might just be my imagination getting to me.On Sandtrap go to the the side of the map that has the shorter arch, walk to the middle of it to where you are standing right in the middle of it and are facing thr other arch, it should form the face of yosemite sam from Looney Toons If you line it up correctly the taller arch and the pillers will form his hat, the walls on both sides of the hall leading down the middle should form his moustache. If you can't see him by that time you're not going to see him.

(No.3)Get two SMG's and find a nice flat non- movable wall best done on Last Resort. Walk up to the wall, get as close as possible, and fire EXACTLY 100 bullets from both SMG's into the wall and in doing so it should spell out one of the game developers names.

(No.4)The Next one is located on the campaign level "The Storm".It includes two eggs the first one is getting up on the beached ship get a brute shot if you can find one a vehicle(ghost works best).Get the person that has the bruteshot get on top of the vehicle that is being driven(once again ghost works best)now back up to where the vehicle being driven is against the
wall, then drive off the little walkway there then when you get as close to the ship as possible while you are still up in the air have the other person brute shot jump of the vehicle and land on the upper deck of the ship.Now if the other people in your group want to see this to tell them to kill themselves. Now watch on as they commit suicide for your pleasure. They should respawn back on the ship with you, now go below deck and you should find a picture of a pirate and I think it says something about tresure.When you and your friends are done looking at pirate booty, jump off the ship and go as far back as you need to where you can get a good view of the end of the ship, and what do you know , it looks like master cheifs helmet.

(No.5) Now you don't have to believe me about this one but it is true, on the first level, I don't care how you do it ,because I don't even know how I did it,somehow glitch underneath the level, and if you actually do it you should see a gigantic egg that says "Prepare for the WARS" in a font like that of which you see the numbers on the cover of the halo games.And on the
the top of the egg once get close to will see a grunt.When he see's you, he will run to the other side of the egg.A couple of seconds later he comes back with a tuxedo and a Top Hat on(I am not lying no matter how unrealistic this sounds) and he does what I assume is the the CHARLESTON which is a type of dance.No Kidding. | [Sent by SirKittyLitter]

• Easy kill wraith

When ever a wraith is near by killing every one, go behind it and you will see this spinny little thing. bash it once or twice, then it becomes a big hole, either shoot it a few times or bash it once more, then you will hear the brute thats driving it yell then it will get all blue then blow up. | [Sent by abe]

At the part of flood gate when your back at the the beggining of the level before it, there is 3 blocks and you hyave to get on top of them so instead of using gernade jump just wait for one of you team mates to stand right next to them and jump on the lowest one and if you look to the right when ur on it you will see one of the corners on the block underneath the lowest one, jump onto it and gernade jump onto the highest block and look to ur right there is a angle on the wall that you can walk on, jump onto it and look to your left and keep on walking when you get to the part whenu have more room to walk turn around and go up the other ledge and when u get up top of there turn around and go up the bigger angle on a diagonal case its a bit patched so u have to scale the patch but when you get up there you can't jump so just walk and there are a lot blank spots that are hollow and you can't walk on so just go on the ledge until you get to a big red crane type theing and jump ontop of it cause you can jump now. u just keep going until you reach a gap, jump over it and go until you hit a wall then look to your left there is a small trench that has no floor but if you stay next to the wall you can scale until the end then you around the corner and you walk on air now so just explore! | [Sent by mcdogit]

• Fog (10 points)

Finish the Campaign on Normal, Heroic, or Legendary, then find and claim this skull.

• Fog Skull

Mission: Floodgate

Effect: "You’ll miss those eyes in the back of your head." -- Your motion sensor disappears.

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!”. Look up and to the right, directly at the roof of the building next to the missle launcher. There is a single flood 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.

• Forge Mode (Basics and how to make Objests float)

The basics of forge mode are;

Turning into a monitor using up on the D-pad.

Spawning Objects with X, scroll through other stuff with the bumpers and spawn with the A button.

Deleting the object that you don't need using Y when the ridicule turns green.

Carry The object by tapping A once when looking at the object.

To make any objects float you must first make a base for them (like a stand)and build on top of that until you can see where you have to stop.(Some maps have more height than others)
Then when you have what you want on top of the other object(s) delete the other stuff under it and it should be floating now.

Enjoy :)

• Funny Conversation

On the second level of the campaign, when you're escorting characters to their ships, you can head the wrong away from where you're supposed to go to complete your mission. If you do, you'll run into two characters (separated by a door) having a humorous conversation.

• Funny Glitch on second last level

In order to do this glitch you must be playing multi player. After you save cortanna and you just killed the power supply things, go to where the hole in the ground is but only have one person fall down. When the place starts crumbling have the person who didnt all down go to where they came in and just look out into nothingless. Ater a couple of minutes you should be able to see what the person that fell down the hole sees. | [Sent by Nick]

Then crouch and on the top there should be a place where u cant jack it. Then old RB and the right thumb stick and slap his head it takes some practice. BUT IT ROCKS! | [Sent by Halofan117]

You'll reach a door that is locked if you do. To the left of the locked door is an open door. Head through the door, and then turn around to find the terminal.

Terminals: The Covenant
Head to the stage's first tower and stand on the elevator. Face the control panel, and then turn left. Jump over the obstacle, and find the terminal you seek.

Head to the stage's second tower and walk towards the entrance. When you come across a locked door, turn around to find the second of three terminals here.

Head to the stage's third tower and stand on the elevator. Face the control panel, and then turn right. Jump over the obstacle, and find the third and final terminal on the stage.

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.

4 5 6 5 7 6 5 4 1 2 3 2 7 2 1 3 4 6 7 5 4 6 5 4 5 3 4

• Sandbox Skull

In Sandbox, fly to the heighest possible point in the map. Look around till you can see the sun (not the "red light" on one side of the map) on the horizon, inbetween two Guardian towers. Turn right and face inbetween the next pair of Guardian towers (so the tower on the right of the sun is now the tower on the left). The skull is located outside of the map in this direction. If you are having trouble spotting it, try and use the zoom of a sniper rifle or beam rifle. There are several methods of obtaining the skull. You can use bubble shields, tube pieces and shield doors to form a tunnel, or you may fly over the skull and drop a teleporter exit so you can teleport to it directly. There are also several maps you can download on fileshare to gain easy access to the skull.

• 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.

• Scarab Mangling

Having trouble with a Scarab? Or maybe you don't want to get on board (and abandon your bright, shiny Scorpion). Try this strategy instead: on the back of every Scarab, there is a circular glowing spot you can shoot to do damage (it is similar to the glowing spot on the back of Wraiths).

Locate the spot on the Scarab's rear armor that is below its rotating anti-air "ass" (or abdomen) turret. A few shots from Hornet missiles or Scorpion tank shells and the armor will fall off and reveal the critical system you normally need to board to wreck. Don't forget that shooting the Scarab's legs will stop it from turning.

• Shield and tank of destruction

• Skull Collecting

While collecting skulls, keep in mind that you have to start the stage from the beginning (not from a checkpoint), but once you acquire the skull you're seeking, you can save and quit at any time without finishing the stage. This will allow you to collect skulls without having to worry about finishing the stage successfully.

• 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 first 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.

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.

• Smarter respawning

When playing in Co-op mode on 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 at the checkpoint.

• Spartan 117

When you beat the game, you will be shown a memorial for the men and women that died in-game. Spartan 117 is one of those considered KIA, but if you wait for the credits to end at the end of the game, you will see that Spartan 117 is very much alive (this only applies if the game is finished on Legendary).

On Tsavo Highway, about halfway through the mission (right after you are forced to walk through a large blue barrier), you will come out of a tunnel on the highway, and see a large pipeline on your left. Drop down in between the two, and run to the wall in front of you. Follow the wall all the way to where it connects with the cliff on your right, and turn to the left. There should be a few ledges--simply crouch jump from ledge to ledge, and the last one should have the "Tough Luck" skull on it.

• 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.

• Weird Glitch

On the mission 'Halo', get 3 of your friends to play with you via Xbox Live, turn the difficulty to legendary and turn on the iron skull (note that if you complete the level in this setup you will also get an achievement). Complete the level up to the part just after you beat the oracle, once you leave the inside of the structure, kill the two sentinels and then turn to the left and head down the slope. Then have a look underneath it and there should be four ghosts, get everyone to take one and then take them back up the slope. Continue with the level until you get inside the structure that seargent johnson came from. Take your ghosts in, hop out of the ghosts and kill everyone. You should get a checkpoint after killing everyone (note that all four players must be in the room for this to work). Now go back to the door in which you got in from. It should be locked, if it isn't commit suicide and you all will respawn and it will be shut. Now go to the door that you are meant to go through, instead of the door being there, instead the wall will show the view of one of the four players. If it isn't there keep killing yourselves until it does happen. It may take a while, it only happened to me by luck. | [Sent by DanielSteffensen]
