I'm up to 5-2 in single player. I am hoping I can finish the game without having to ask someone to help me in coop. I am surprised at how much fun I am having playing it. I think my expectations were lowered quite a bit in the weeks before launch, mainly due to the overall tone of the reviews and things people had been saying online. I am really looking forward to playing coop at some point down the line, hopefully with some CAG's.
