Will this affect my game?

Will me and my friend both brought BF:BC2, but his xbox fell over and it burnt his disc, so he said that if he could use my disc, download it to his xbox and it shud be okay, cuz apparently some of his maps dont work now on multiplayer

No it wont touch yours unless he knocks his xbox over again in rage

yeah, you can take your disc round his, install it on his hard-drive then he can play his disk.
or he can just get it cleaned for like 3 quid from game.
