Halo 2 Hint: Reset Thy Ammo
Expended all your ammo at the end of one stage and don't have enough to muscle past the start of the next one? Save and quit your game -- provided you acutally unlocked a new stage on the Stage Select, you can head back into your campaign (via stage select) and get a fresh batch of pre-assigned weapons for Master Chief.

Halo 2 Unlockable: Blind Mode
At the beginning of the episode Outskirts, go through the first opening but do not head down the ramp. Instead, jump up onto the flourescent lamps over the doorway. From there, you can jump-crouch-jump onto the sloped roof to the left (jump and hold the crouch button at the peak of the jump to get onto the ledge).
Once on the rooftop, look for a narrow alleyway directly to your left. At the end of the alleyway are some grenades and a skull. Picking up the skull (hold the X button) will unlock blind mode, which removes all traces of your HUD.

Start a co-op game with a profile with access to the last episode (The Great Journey) and a completely fresh profile (i.e., one that has not even started the campaign game).
Fight to through the last episode until the players need to board Banshees to progress.
Have the new profile player perform a barrel roll (both directions) and a Loop-the-loop (stick down and A button).
Complete the game as usual and the new profile will have access to the Foundation Map. Since profiles may be renamed, you can delete your old profile and rename your new profile w/ the new map.

Halo 2 Cheat: Grunt B-Day Skull
Difficulty: Legendary
Level: The Arbiter
Word: Grunt Birthday Party
Effect: Shoot enemy in the head and they will explode.
The very first time you get a banshee, fly down, below you is a large beamlike structure (not to be confused with the one directly below you that turns and goes vertical) running from the arm of the station you just came out of to one exactly like it on the side opposite. Below this structure are 3 cylinders hanging down, with cylinders of light shooting out of the bottom that look like they are what keeps the station floating. If my explanation is too vague, they are the absolute lowest parts of the station. Now go to the middle engine and land on the top part of it. This and the other engines connect to the large structure mentioned earlier. The tops of the engines come up to meet the structure at an angle, where this angle is under the connecting structure and coming up to meet it, there is a place to walk (like being under a bridge). Under one side you will see the six grunts with the skull in the middle.
