[quote name='MIX_MASTER_ICE']There's a reason why this dropped to 19.99. Pretty bad game and like has been mentioned, controls are poor.[/QUOTE]
It's all developed around the co-op experience, so if you don't have a friend to play it with, it's not going to be near as fun.
Controls are fine. The only place you might have reason to complain is when you have to rely on the other person to steer, or whatever. There are a few places along the way they use co-op sequences (like carrying the bomb in Gears 2) to try to screw with you, but as long as you're not relying on the AI, it's still good times.
My only real complaint about the game is that when I last played it a few months ago, it seemed like the multiplayer was still pretty laggy, and it would take a couple of seconds after you hit the analog stick for your gun to swing around.
