My 5 year old brother and I just beat halo 3 again, this time in heroic difficulty and in two hours, i didn't realise you could just run through the levels without killing anything, we skipped all but the last cutscene ofcourse as we have seen them numerous times but thats ridiculous that this game can be beaten in under 2 hours, i dont care if it has multiplayer, i dont have live and i now refuse to get it due to too many games relying on the multiplayer for it to be good, so stuff them, im sticking to the story missions nothing else.
