Teh internets aren’t happy. Apparently co-op play in EA’s Army of Two is region-locked, so Europeans can’t play with Americans.
The game’s instruction manual informs, “”NOTE: The online game modes in Army of Two are not cross region compatible and is only supported between PAL discs.”
No reason’s been given for the move, but apparently it applies to both PS3 and 360 versions. Just hope you don’t have too many American friends you want to play Army of Two with, innit.
