Just got done beating Gears of War 2 Co-Op campaign and it will be a little while before I can afford the 3rd one. What are some really good Co-Op games for the 360?

Best Games for a co-op story mode?

Best games for co-op play? (Offline) Like Call of Duty Black Ops where you can set up against the cpu and battle them.

From personal experience:

Any of the Halo series games.
Army of Two: 40th Day.

Those are some good multiplayer games.
