Yesturday I played nuketown and it didn't freeze and zombie map five but eventually it stopped letting me play nuketown or zombie map five it would just freeze in the loading screen it worked yesterday but later on that day it started to freeze in the loading screen and also the disc is clean and has no scratches and tried to install it to the hard drive but stopped eventually and said the disc might be dirt or scratched the disc is not dirty or scratched I just got the game the first day black ops came out
