Unlimited ammo: This can be done in single player and multi-player modes. It will work on the hand gun, assault rifle, sniper rifle, and rocket launcher. Stand over one of those weapons on the floor so that it highlights on your screen (including alien weapons). Press X to reload. When the hand pulls out the magazine, hold X and your weapon will be thrown to the floor and make a reloading sound. Do not pick it up until this finishes. When it does, walk forward and press X to pick up reloaded weapon. Note: When using guns, do not empty the clips completely -- leave one or two rounds before attempting this. Also, with the rocket launcher, fire one rocket stand, over any weapon, and do the same as above.
Unlimited ammo (2): This cheat can be very tedious to get, but is very useful. Start on the Pillar of Autumn level. The glitch is easiest to perform on this level. There is an area that is a long, wide, empty hallway with the Grunts at the end. Kill them and go into the tunnels. You must have a Plasma Pistol and be in cooperative mode for this to work. Have player one find the place where it says "Loading... Done" and make him stand directly in front of it. Have player two charge his Plasma Pistol, and hold it down until it starts to shake violently. It should be shaking so much that it is blurry. Then, have player one move through the loading point. If it player two's screen zooms out onto player one, and says "Waiting to respond" (as if he just died), then the glitch worked. Player two should zoom back in, and still be charging his pistol. It should stop vibrating, but still be glowing. You now have unlimited ammunition. Note: You can switch weapons one time. For instance, if you have a Plasma Pistol and Assault Rifle, you can switch to the Assault Rifle and still have unlimited ammunition. However if you switch back to Plasma Pistol, it will be normal. Also, if you pick up a weapon, then the unlimited ammunition will be lost.

343 GUILTY SPARK GLITCHES
Trip to heaven: As soon as the Pelican is about to let you out, throw a plasma grenade out of it while you will stay in the Pelican. It will take you to a high land, while a flying explosion will kill a group of Covenant. You will also see the end of the level -- all whiteness. The Pelican will land and let you out. You can walk through background forests, and if you go far enough, you will see a marine in a brown suit standing there for no reason.
Mendoza alive: Immediately after exiting the Pelican at the start of the level, run to the front of the Pelican to find a rock. Jump onto the rock and then onto the Pelican. Run to the back of the Pelican. As the Pelican lifts upwards to take off, you will be able to see a ledge. Before the Pelican takes off, jump from the Pelican to the ledge. Continue on the ledge and eventually you will see a Marine. He is Mendoza, one of the marines from the intermission sequence, showing the introduction of the Flood. He is unarmed and he does not move. Killing him does not affect anything later in the level.
Floating guns: Immediately after exiting the Pelican at the start of the level, run to the front of the Pelican to find a rock. Jump onto the rock and then onto the Pelican. Run to the back of the Pelican. As the Pelican lifts upwards to take off, you will be able to see a ledge. Before the Pelican takes off, jump from the Pelican to the ledge. Continue on the ledge, looking off of it every now and then to see where you are. When you get to the doorway that you would enter to get to the elevator that takes you into the complex, walk of the ledge slowly. Do not walk far away from the door. After entering the door, walk out of it backwards and you will see floating guns shooting at grunts. If you hit the guns, they make a metallic thud noise. After awhile they will disappear and you may continue the level.
Floating guns (2): Go to the energy bridge that you can turn off and on. Turn the bridge on if it is not already in that state. Get a gun and place it on the energy bridge. Get off the energy bridge. Turn off the energy bridge and the gun will be floating in air.
Floating guns (3): Throw a grenade immediately when the FMV sequence ends and you will stay on the ship. Make sure to throw it before the checkpoint appears. When you get off the Pelican, turn right and go straight. When you reach the edge, follow it until you get to the room where the elevator is located. Jump down and go in. If you look around very quickly, you will see floating guns shooting at the aliens running out.

ASSAULT ON THE CONTROL ROOM GLITCHES
Bypass sections: In Assault On The Control Room, towards the end of the level you will cross a snowy bridge with two Banshees on it. Run and quickly enter one of the Banshees. You can skip the last part of the level by simply flying to the top of the large structure below, where the large door is located. If you are in cooperative play mode, have the other player die and they will reappear next to you. Have them open the door and then you can simply shoot down the masses of Covenant waiting inside. Fly inside and have the other player open the next door. The third door, before the control room and level ending sequence, is now in front of you. Arrange it so the second player is now in the Banshee and fly it directly in front of the door. Have the first player open the door. If done correctly, the Banshee will fly in, killing the first player. The game will not know what to do and will show various camera shots of places in the room. Eventually, Cortana will appear out of the console as she is supposed to and will carry out her conversation with the disembodied voice of the Master Chief.
Phantom voice dialogue: In Assault On The Control Room, get to the snow covered bridge. Rush to take control of one of the Banshees, to skip the last part of the level. Kill all the Covenant and head towards the control room. Take care of the Covenant on the way, and park the Banshee next to the door operator. Open the final door and quickly hop back into the banshee. Start moving forward as the doors open. The FMV sequence will start, and the Chief will jump out of the Banshee and immediately get run over by it. He will be laid out on the ground, but the voice parts will continue. The Chief will work his way to standing while leaning on the assault rifle.
Double music: Get the first early Banshee during the part where you have the tank and have to kill the tank on the frozen lake. Take the Banshee to the part where you find the marines down the slope and wait at the top of the cliff. Wait until the Covenant dropship arrives and the music starts to play. Then, immediately fly over the structure with the tunnel underneath it. If done correctly, the music from this area will not stop playing. Other music will play along with it.
See through door: Play through the level and get the early Banshee on the land bridge. Fly to the top of the pyramid. Fly through the tunnel until you get to the door outside Halo's control room. Do not open it. Fly to the top of the door, then point down. You should be able to see the Halo control room without opening the door.
Wraith Tank: Take the Scorpion Tank and flip the Energy Tank. The man will fall out. Go up to the tank and the game will say press X to flip Wraith. However you cannot drive it.
No enemies: Kill the Covenant and get to the first bridge. Get to the lower level of it and at the side closest to the entrance, fall onto a nearby ledge. You will make it with three power. If playing in cooperative mode, go to the lowest point, kill your partner, then fall. With some practice and luck, your dead partner will re-spawn on another lower ledge. Now, walk as far to the right as possible and fall where some marines are standing. You should make it with one power. Have your partner kill himself and re-spawn down with you. There will now be no enemies during the rest of the level.
No enemies (2): This trick can only be done in two player cooperative mode. After exiting the Pelican, continue normally until you reach the first bridge where you can see the Pelican descending. After exiting the door that opens to the bridge, have one person run to the left edge against the wall and jump over the edge. They will land on a ledge and will live (unless you jump too soon). Meanwhile, have the other player kill himself. The player on the ledge has to continue on the ledge until they reach a point that has a slope off the ledge to the left. Then, slowly walk off the ledge. If done correctly, the dead player will re-spawn on the overhang near the bottom of the chasm, while the other player continues falling to his doom. Note: You sometimes may need to kill the enemies on the bridge or the dead player will not re-spawn. Walk on the overhang until you reach another slope off to the left and slide down. If done correctly, you should land with one brick of life left, or rarely, no damage at all. Continue forward in the level as normal, however there will be no enemies. When you reach a door in the wall of a mountain where two bridges can be seen overhead, there will be a Banshee nearby. One player has to hop into the Banshee, and the other has to die again. Fly up to the bridge that is closer to the mountain wall and go to the door that is on the wall that the door on the bottom was on. From there, just continue as you normally would until you finish the level. this Can be done under any difficulty setting.
No enemies (3): In two player cooperative mode at the first bridge you encounter, look to your left. Once you first step onto the bridge you can see a ledge. Run and jump as far as you can off to the left while hugging the wall. You will hit an incline as you fall that will slow your descent enough not to kill you. Once there travel down to a thin strip on the ledge. It may look as if you will fall, but hug the wall and you will not. Continue down until you reach a "V" in the ledge. Once you reach the bottom of the "V", turn around and walk about four feet back the way you came from. You will have to practice to locate the correct spot. Walk off backwards very slowly. The idea is to stay extremely close to the cliff as you fall. As you fall, try to run up the cliff face. You will fall until you hit a white, snowy lip. The goal here is to hit the right part of the lip. If you do, the level of incline will slow your descent and keep you alive until it launches you down again. If you are moving too fast you cannot respawn player two. This lip will slow you long enough to respawn player 2 securely on the lip. After this, you can try the same trick to get down to ground level. Note: Jumping while hugging the wall and falling may give you a foothold. Once you reach the bottom, some Marines will be grouped and a Warthog will also be there. If you hide the Warthog in the building, you will have two Warthogs if you go up to the bridge and come back down. If you continue the mission, you will encounter no enemies save one tank that just sits. Destroy it if you wish. If you want to fight you can go back up the elevator and to the bridge. The enemies will not appear until you reach the middle of the bridge.
Ignored by Covenant: Near the end of the level, bring a Ghost. Do not open the door where the Covenant rush out (the group with a gold swordsman) on the path leading to the control room. Take a Ghost up there. Strafe towards the door, and press X before you hit it. The Ghost should knock you through the door. Sidewinder sneak inside, and the group of Covenant will move and interact, but will not notice you. You can hit, shoot, stand on them, etc. They resemble odd symbols and markings. Note: Opening the door causes them to come alive. If they are dead, nothing will happen.
Frozen Marines: Shoot the Banshee off the ledge before you pass the ice with the Wraith tank on it. Then, take it into the building until you get to the big room. Destroy all the enemies, then open the next door and quickly fly out. When you get your cheakpoint, go back and look at your Marines. They will be frozen in the running position. This happens because the load point went far ahead.
Frozen Master Chief: At the end of the level, take a Ghost, open the door, and quickly get back in the Ghost and drive it sideways up the center of the platform. The Master Chief will not walk forward during the rest of the sequence. Instead, he will get stuck behind the Ghost, unable to move.
Snow: Pause game play when standing outside in the snow. The snow keeps falling, but nothing else moves.
Crashing Pelican: This trick can only be done in two player coop mode. After exiting the Pelican, continue normally until you reach the first bridge where you can see the Pelican descending. After exiting the door that opens to the bridge, have one person run to the left edge against the wall and jump over the edge. They will land on a ledge and will live (unless you jump too soon). Meanwhile, have the other player kill himself. The player on the ledge has to continue on the ledge until they reach a point that has a slope off the ledge to the left. Then, slowly walk off the ledge. If done correctly, the dead player will re-spawn on the overhang near the bottom of the chasm, while the other player continues falling to his doom. Note: You sometimes may need to kill the enemies on the bridge or the dead player will not re-spawn, but doing this will make it so that you cannot see the Pelican crash. Then, walk on the overhang until you reach another slope off to the left and slide down. If done correctly, you should land with one brick of life remaining, or rarely, no damage at all. If you were quick enough, the Pelican should be dropping off marines and a jeep. The best way for the glitch to work is to have one person enter the Pelican and have the other drive the jeep. Continue following the Pelican until you reach the Scorpion Tank. The pelican crashes next to the already crashed Pelican. This is strange, because they are actually the same Pelican.
Get back into Pelican: Immediately before you get out of the Pelican, it will prompt you to hold X to get into the side seat of Pelican. Hold X and you will get back into the Pelican. You will fly down with it until it disappears. Note This can only be done in cooperative multi-player mode.
Survive elevator shaft fall: Drive a Ghost past all the Grunts, Elites, and Jackals then get it on the elevator on the floor. After you push the button to go up, quickly get back on the Ghost. You will fall through the floor to the bottom of the elevator shaft without dying. Note: You will have to revert to a saved game, as you will be stuck there.
Fall through elevator with Ghost: Find a ghost after you come from outside when they become available to you. Stay in it all the way through the building (which is possible). Once you get to the doors that you think are impossible for it to fit through, get out and open the door. Hop back in to the Ghost and continue through. Once you get to the elevator, hop back into it . You will soon fall through the elevator and land at the bottom of the floor, still alive.
Unlimited ammo: It is possible to get unlimited ammunition in this level in multi-player mode. To do so, get to the under ground tunnel and to the loading point. Have one player reload and the other go through the loading point at the same time. The player that reloaded will have unlimited ammunition for that gun. However, if you change guns or press X you will lose your unlimited ammunition. You can go back and do the trick again. Both players can have unlimited ammunition. If player two reloads his weapon as player one crosses the checkpoint, the weapon being reloaded will never run out of ammunition. You will still need to reload it as usual but the clip value will not decrease. This state will continue until you change weapons, or die.
Floating tree: When you get to a part where tanks are firing from above, take a tank and wedge it in between two rocks on the left side. Then repeatedly hit the tank with a Warthog from behind. You will get the tank stuck between the rocks. Have a player get in the tank and point the barrel at the ledge. The player in the tank has to keep going forward in it so you do not kill your partner and or slide. Then have the other player has to get on top of the tank barrel at the edge and jump on to the cliff. When up there, you will run into a Covenant tank. After it is destroyed, look around there to see a floating tree. If you go under the tree and jump, you will hit your head on thin air. Note: This requires precise teamwork.
Floating tree (2): This method does not take teamwork nor do you have to be in cooperative mode. Kill all the people in the section where you can get the Banshee early and the Covenant Tank is on the frozen lake. After you get the tank and go through the tunnel, kill all the people including the Banshee (unless you already knocked it down). Then, take the tank and back it into the rock on the right side (back it to where the rear is angled towards the corner on the right side ). Then take a Ghost and ramp it. This might require a few attempts. It helps if you tap X a second before you hit the tank, because it raises the nose. You will find another Covenant Tank on top. Near it are two trees, one of which is floating.
Bouncing plasma grenades: When you get to the elevator, hit the button to make it go down and throw a plasma grenade in the center of the elevator. The grenade will bounce up and down.
Floating plasma grenade: Get on one of the double leveled bridges with the breakable glass. Throw a plasma grenade onto the glass. After you have thrown it, shoot the glass under it. The plasma grenade will float, as if still on the glass.

BLOOD GULCH GLITCHES
Dirt cloud in mid-air: In multi-player mode, when a grenade explodes it leaves behind a dirt cloud. Stand still, throw a plasma grenade, and before it explodes, throw another plasma grenade on top of it. The first explosion will toss the second grenade in the air. it will explode in midair, but leave a dirt cloud as if it exploded on the ground.
Invincible while in tank: In multi-player mode, park another tank with the front facing you. Then, get to full speed in a tank and ramp it. If done correctly, you will land on the base, making you invincible as long as you stay inside the tank.
Unlimited rocket launcher ammunition: Shoot a rocket launcher at a warthog five times, then get inside. Jump out, shoot two rockets, and throw a grenade at the red base. Have someone kill you. Then, have your opponent exit, then you, and go to side winder. Find the rocket launcher and it will automatically be at only one shot. Shoot it, and the rockets will never go down. Note: If you die, this will no longer work.
Get Warthog and Ghost on building: Play the level in multi-player mode. Take a Warthog and set it up all the way against the building where there is nothing covering above. Then get another Warthhog. Get in a straight line in front of the first Warthog and drive very fast. Slam into the Warthog. It should go in the air high and land on top of the building on Blood Gulch. You can now guard your location with the LAAG Gun on the Warthog. The same thing can be done with a Ghost.
