Halo Reach. I jumped in a warthog tring to get a gunner. Teammate throws a grenade at me, I guess he wanted the same. I walk up and smack him, then proceed on my way. I notice on my radar he was trying to run me over, so I jump out of the way. This goes on a few times until I finally jump on the back. I know this kid is pissed and will try to drive us over a cliff. I jump out right before and he ends up killing himself, me tbaging and shooting the water. I then leave the match, the end.
