Black Ops 2 disk read errors?
If you’re planning on buying a hard copy of Black Ops 2 you might want to wait. It seems that some retail copies have the wrong files on them. A few Steam users are reporting that their second disk is actually Mass Effect 2. Now if this happen on Steam you could just simply let Steam download the missing files after you have the game linked to your account. Not sure how EA and Treyarch will deal with this for console users.
