I have tow xbox 360's, one the black slim manufactured 10/17/2011, and the star wars r2d2 edition made 11/10/2011. both og them read and play black ops 2 with no freezing or disc errors. only problem is on campaign, everything is green, vehicles, people, everything. this is on both systems. I have been searching for awhile with no luck. i tried all kinds of keyword combinations but nothing. any insight on this problem?
