California resident Randy Nunez a federal class-action complaint against Microsoft and co-defendant Bungie over Halo 3 seeking (unspecified?) damages. His argument is simple:
"Halo 3 does not functino with the Xbox 360, and to the contrary, attempted use of Halo 3 consistently causes the Xbox 360 to 'crash,' 'freeze' or 'lock up' while the game is being played."
