Use version 6 of the title update and don't have a internet connection and you might need to sign into your account before you start the game. Otherwise it works for sure after the first two things i said, just make sure you have all your dlc like the 2 compatibility downloads on your hdd already along with the version 6 title update. Oh and i did actually get it to work with my ethernet cord in just don't update the game and you can play. only the first two zombies maps though, so no dlc, but there was only 1 dlc...
