ok once again ill say it for the people who dont -blam!- read , FIREFIGHT CAN BE PLAYED ON XBOX LIVE
Drop feet first into a new way to play Halo with the cooperative campaign mode, Firefight. Form a squad of your friends over System Link or Xbox LIVE and put your skills to the ultimate test against the invading Covenant war machine for glory, high scores, and achievements. Do battle in multiple environments, on foot or in vehicles, and against increasingly difficult waves of Covenant attackers while Halo 3's skull modifiers progressively activate to up the ante.
