We're also very interested in checking out the new co-op mode. Up to 12 people can band together and fight 20-30 AI-controlled opponents that have four levels of difficultly and retooled intelligence. They'll run for cover, bum rush you, retreat, and surrender, though just keep in mind that the higher the difficulty, the better their aim. They also feature randomized positioning, which basically means that the game will adjust their starting locations each time you start a match, and doing this should keep things varied and unpredictable.
