My Xbox 360 will not play call of duty black ops2. Every time I try I get unrecognized disc error. It isn't the disc it wroks fine in 2 other systems and it isn't the disc drive because I don't have problems with anything else. I called customer service and they were a joke, they only ran through troubleshooting tips I have already tried a dozen times. Can anyone help with this problem. Microsoft really needs to get their act together there is a problem here and I've looked into it there are hundreds of others with the same problem with only this game.
