I can't say i care. Played through Halo Reach over christmas (twice). Storyline is nothing to write home about and once you up the difficulty all you do is snipe and abuse the crappy AI. Taking on Zealots is a waste of time as they will almost always kill you before you kill them. Multiplayer was a joke too, you spent most the time letting autoaim do the work for you, other than that it was dull. Doubt it differs all that much from the other Halo's... Not an experience you couldn't get better from existing games.
