Call of Duty: Modern Warfare 2, due out worldwide on November 10, won't have a campaign co-op mode at all. Instead it will have a two-player Special Ops mode, “designed to be replayed over and over again”.

He said: “We don’t do co-op in our story because we’re crafting a very specific experience and we don’t want to ruin that by cramming co-op into it. We take the moments that work really well with co-op, we bring them out and we put them in Special Ops.”

When asked why Special Ops was limited to two players, not four, Bowling replied: “Two player seemed to be the magic number for co-op. That’s when it stayed really fun and intense without becoming a clusterf**k of things. We just found that two-players was the most fun.”
