[halocheater]

Hey all Halo lovers i found a cool glitch on Halo and I had nowhere else to put it.do excectly as i say and it really might work
1.in the pillar of autemn(first level) you go to the place where there is two blast doors an each side of you
2.wait till each door closes you go into the double doors
3.you know when the Elite tries going back...Well stop him
4.he might go foward if he doesnt stop trying
5.if he goes forward thenrun foward as fast as you can then when the door closes stop
6.if you did it right he might just stand there not moving
Thats it and dont leave any comments like "wrong site noob" or something like that
