Hey guys, just giving you a heads up. I don't know if it's because I'm on the beta dashboards, however when trying to play this game. It boots, however when I exit the game, eject it and then try another game. I get dirty disc error. With EVERY game! Of course Rebooting fixed it. Not for my friend though, he had to go back to Sainsbury's where he purchased the console and get a new one. So after rebooting, and booting up Ground Zeroes again. I then ejected and tried again and the same thing happened. BE AWARE!
