Basic Glitches of Halo 2:

Sword Canceling: Lets you lung at an enemy but not hurt them. Great for getting through invisible walls. Just press x and right trigger (r) at the same time (while facing your enemy, reticule has to be red).

Rocket Canceling: Lets you lung to an enemy that's far away. Just have your reticle red and then press x, y, b, and r at the same time. Have your r.l. empty so you don't shoot your partner. NOTE: Very hard to do.

Sniper Canceling: Similiar to rocket canceling only lets you lung from to enemies, practically from across the map!! Bungie took it out with the auto update though....

Butterflying: Very useful to getting ontop of high buildings or rooftops. NOTE: Works the BEST in corners. Very hard to do in the open air. Have someone stand and look up with a sword. Then have someone jump ontop of them. The person ontop's job is to keep jumping. The person on the bottom's is to keep pressing x and b at the same time. You have to melee not press r. If you do you'll lung at them and won't butterfly. Be careful to press x and b at the same time. Reason being is that if your looking at the person above you if you accidentaly sword you could assassinate him and you'll fail. TIP: The most effective way is to put your index finger on x and your middle finger on b. Make sure it's the same time, reason being because your fingers should probably be tapping them at the same time because they're on the same hand. When you get this all down, you and your partner will start rising into the air. You can then reach hard to reach places. If your good enough you can get to REALLY tall buildings. Practice and good luck.
