We called it from a mile away. When Mass Effect 3 was announced mid-last year, we said, "There's gotta be something different about this game to make it wrap up in an epic fashion." We had already guessed stuff like story twists, new weapons, revealing Tali's face, etc., but the big thing we mentioned was "multiplayer". And even though competitive would be interesting, we knew co-op would be the big idea. And yesterday, Bioware announced that it was bringing it to Mass Effect 3, with four-player support and a new tie-in to a "Galaxy of War" feature. Damn, we're good.
