I recently (3/22/13) bought a new 360 250GB console from a retailer and the Black Ops 2 game. I set up the xbox and connected to xbox live and played for about 30 min. and then the game froze. I then tried to install the game to the hard drive, hearing that it would run easier from the hard drive than from the disc player (I know the disc still needs to be in the tray) and it woud linstall to about 40-50% and then tell me the disc was dirty or something like that. I went back to playing from the disc drive and it froze randomly twice more. I also tried to install it a few more times each time to no avail. Any thoughts? Both the console and game were brand new.
