The Prestige Shop is unlocked after Prestiging for the first time. After you reach rank 80, you can reset your rank by Prestiging, but each time you Prestige in MW3, you will receive one token that you can use to unlock Prestige Rewards.
There are a total of 10 Prestige Levels.
In the shop, you can spend your tokens on the following rewards:
If you've Prestiged in any of the previous Call of Duty games (Xbox 360 and PlayStation 3 only), you will automatically receive one bonus token for each CoD game you've Prestiged in. You can only receive a maximum of one token per game, regardless of the Prestige Level in that game.
