Halo

In some levels the covnet are sleeping or not paying attention. Simply pistol whip them. But, if you miss they will get up. You still have a chance to kill them. DON'T SHOOT THEM. Pistol whip them before they shoot.

This is NOT A CHEAT!!!! It is just very funny!!! OK, so as soon as you get off the Pelican(the big ship that you see at the first cutseen in the level) press X and you will get back in. NOTE to press it AFTER you get off(you get off automatically) and time carefully. The pelican will take off with you in the sideseat. NOTE YOU ARE JUST IN THE SIDESEAT!!!!! After it takes off, some covenants will attack you. They won't kill you. Don't stay in the Pelican for too long(instructions on how to do a safe evacuation at bottom) or sooner or later, everything will turn lightblue, and you will fall from the ship, on a cliff to your death. Your new checkpoint begins at the point the Pelican takes off, until you reach a new one. Now, to get out, you must make sure that you are still JUST taking off. Press 'X', I know you're surprised, but here's the hard part: surviving the fall, which is still a long ways up. You may have heard of this glitch before, but at any heights in which you WON'T die while you're in the air, but rather when you hit the ground, as you hit the ground, push the right stick on your controller inward. This is how you crouch, as I'm SURE you're aware, or atleast, now you are. Well, I'm happy with the knowledge that you are ready to try without losing a BIT of your shield. NOTE that if you time your fall incorrectly, you will lose both shield and health and there is no healthpack nearby. FROM THE PELICAN you can shoot foes, and look around. NO MOVING, and at certain points your aim is readjusted. ENJOY!

Now, the rocket launcher or the shotgun seem to have the deadliest melee, but in truth, the Assault Rifle has the most powerful melee in the game. One smack from the side of this gun is strong enough to knock a grunt or jackal off their feet. Be sure to have this weapon if you plan to melee enemies.

In the end bit where you have to collect captain keyes when they say look out, hunters they are on the left side of the ship and when he hits the hunters they are on the right side now thats just plain weird.

This isn't so much a code. It's just something that shouldn't be where it is. In the level "Guilty Spark 343", there is a crashed Covenant dropship just around one of the corners you must turn (the second or third, I believe). Up above this dropship is a tree jutting out over a ledge. On this object is a Flood-infested Elite (the bulkier Flood ones that don't pop). It appears as you come around the corner and runs back along the log after a few seconds then disappears. It is named 'The Yeti' because it diappears whenever seen. This is really weird because the Flood have yet to be introduced at this point. Also, the Yeti is invincible. You can sneak up on it from behind (which is too long and tedious a subject to go into), but don't have your co-op partner go around the partner until you're in position. It can withstand a pistol whip to the back of the head and a plasma grednade, so we just gave up. It's really fun, though. I suggest you try it.

At the end of the Truth and Reconciliation, when you get to the docking bay with Captain Keyes you will meet a whole slew of Covenant waiting for you. Go strait to the controll panel-that you would normally hit when the battle was over-and hit "X". Then fight normally.

If that reckless Keyes gets killed, it will show his corpse, then go to the cut-scene of you activating the control panel, then the screen goes white, and you go strait to the next level.

You can also kill Keyes yourself just to end the level early.

When you do the assault on the control room go onto the first bridge were the glass breaks and clear all the enimies. After that go down bottom and the way you came one at a time jump off and youll land on a platform then the other person jumps and then if they die thell respawn on the platform then one at a time fall down and there will be another platform. Then the other person die and respawn were they are then youll be able to fall down and there will be two banshees were you are.

In co-op mode,if there is a ledge to high to get to have one player stand right up to it and the other jump on top of them to get up.This is really fun,but beware,if the bottum person is killed the top person may be also.I'm not sure why,maybe just a glitch on mine.

When playing cooperative mode in Halo and your running low on ammo for your assualt rifle, pick a spot that is clear of any ammo you dont want, and have your partner hit you in the back of the head. All of your weapons will drop where you fall and you will come back with another assault rifle and an alien pistol. Just walk over your weapons you had and your assault rifle will have 120 bullets more than you previously had. You and your partner can do this if your running low on health as well, as long as one of you are alive when it happens.

Beat the game on the Legendary setting to unlock a longer, different final movie.
