Answer:

I would suggest you go to www.youtube.com to check this out. That%26#39;s how I worked my way into being able to do all of the tricks for Halo 2, as well as Super Smash Brothers Melee. Just search for Halo 2 tricks or glitches and see what you find. Alternatively you could go to a Halo 2 forum, which are undoubtedly an abundant commodity.
