Mass Effect 3 Exec Producer Casey Hudson says that cooperative online missions will be a feature of the next edition of the ME series. This moves the popular XBox game into MMO territory when the next game comes out in March of 2012.
Full details are said to be forthcoming in the December edition of XBox Magazine, but speculation about the MMO effect being added is still flying. This addition will definitely move the game into a new dimension.
Bioware, Mass Effect 3′s producer, has officially confirmed the multiplayer coop missions and that more information is coming soon.
