Co-op is what kept me at it because I find the shooting incredibly frustrating in both games of the series. In a way, the shooting in B1 and 2 is more realistic than most with lots of recoil. It's also very unrealistic in that all the enemies are more skittish than someone on two cans of Monster and a triple vente cappuccino. By the time I've got the head shot, four guys are breathing down my neck, and a grenade is at my feet.
