If you have this game you may want to sell it. It's going for over £50 on Ebay. Me and my friend finally got this game and played some co-op, so I made a video :)
Edit: Someone told me it's so expensive because the dlc isn't available on live any more only via the disc.
I seem to have made this topic twice? I don't know how I did this and did not mean to spam - Sorry.
