If you purchased the Call of Duty DLC maps that came out this week you might be disappointed to find that the maps will only work on the Elite profile and not for all profiles on the console. This is against what the download terms and conditions state "You can use this item on the first Xbox 360 console you downloaded it to. Access to this item will also be granted to all users on this first console."
I am sure they will fix this issue but this is just another issue frustrating Call of Duty Modern Warfare 3 players. This after many players getting their stats reset or account banned because of the "prestige token glitch".
Activision has yet to release a response to the issue.
