Well the resident evil 5 demo hit xbl today and i downloaded it and its awesome. its everything i hoped it would be, its like 4 with a friend and great graphics. also they switched the aiming to right stick, feels much more natural that way.
on a side note, that damn chainsaw guy took forever to kill. i put like 10 rifle rounds and a mag of pistol into him and i blew up a barrel right at his feet.
