I'm looking for help with the co-op challenges and also the Purewal Memorial Cup achievement. I can help others with any achievements they need. I really don't care to do yet a 5th or 6th (I lost count) playthrough of the campaign for the Purewal Cup so if anyone has a game they can load up and help me get it that would be awesome. Message me on Xbox Live if you're interested.
