Ok......
I have to admit it was better. Since I see you have Halo 2 I will tell you some lil glitches.
1: Sword Cancel- First get a rocket and a sword. Face a guy until it gets red for the rocket on the aiming thing. Then quickly press RYX and keep on repeating it until you fly to the person. If he is straight on the ground press A for the sword cancel jump.
2: Sword Cancel #2- Easy one for everyone. Go into the side seat of the warthog and put out the sword. Then lock onto a guy beside u outside of the warthog and press R. Now let the other guy run somewhere. When you want to get out of the warthog and you will fly to the person.
3: Boxxies go red blue or PURPLE!- In that one level uhhh where there is the beam rifle in the middle of the level between the red and blue base. That's the level. Then get a blank box into the portal thing and it will fly up. From there push the box into the red base and it will go red. Push it to the blue base and you got blue. Then push it to the middle and you have purple.
Those are 3 easy ones and well I don't wonna reveal anymore even though I know like 20 :P. Search for glitches it's a bunch of fun like going on top of levels like headlong.
