Aye, multiplayer only. I'm happy with that. I consider most FPS games to be effectively multiplayer only, tbh. Never did play the campaign for the last COD (though I did play it on the current one). COD, Battlefield, Halo - they're all about the multiplayer imo. The single player story is sometimes decent (and was pretty enjoyable on most of the Halo games I've played, tbf) but it's the multiplayer that keeps you coming back.
