Narrated by Patrick Stewart (reprising his role as Professor Charles Xavier from the X-Men films), the game's plot is built around the Prime Sentinels retrieving the head of Bastion, and Bastion's subsequent attempt to wipe out mutant-kind. The game is a fighting game. The GameCube version includes exclusive modes: Team and Practice. The Xbox version features an extra stage and the ability to play as Pyro. (wikipedia.org)
