Valve's latest is fantastic and the co-op mode only sweetens the deal. If you've got a friend who's willing to take this challenging ride with you, you're in for a treat. This new video highlights the coolness of co-op fun; it's all about working together to solve any given problem...and remember, those problems can be awfully difficult. But hey, with two minds working at the issue, things are always easier!
