Seriously? I get that Halo was GREAT split screen but unfortunately if you're unfamiliar with what they're making now it's called an MMO, there is no where in the game where you're offline even when roaming the world. There is no way that they could make split screen work in a persistent online world where you need to CREATE a character to begin and LEVEL it up so you can get to tougher Zones. Sorry, it [b]ISN'T[/b] possible, just enjoy the game.
