In Infection try to get as close to 7 people and search, either don't infect each other or only infect the randoms. Go have a dance party in a room away from the random, watch his reaction upon stumbling onto this scene If someone betrays you for a vehicle, grab plasma pistol(unless elite slayer since you can spawn with one) repeatedly disable said persons vehicle and t-bag it. More win if you both die and they rage at "how you wasted the vehicle". [Edited on 02.03.2011 9:57 AM PST]
