You can't play this game (properly) without a controller. I only bought this game because it came with the free demo pack when you bought the original xbox and I did not understand this game as a kid.

Fix Online Please, too much lag, constant disconnection, and game crashing. The whole point of buying this game was to play co op with a friend but we can't even finish the 2nd mission with all these glitches. Ended up playing single player by our selves.
