We're also rewarding veteran Call of Duty players who have prestiged in all past Call of Duty games since Call of Duty 4: Modern Warfare! You've just had to prestige once to unlock the token for that game.



So this weekend, starting at 10AM on Friday and going until 10AM on Tuesday, we're turning on Double XP on Modern Warfare 2 and Black Ops to give you the opportunity to rank up and get to that first prestige, if you haven't already, before the launch of Modern Warfare 3!



One Prestige Token max will be rewarded for each game you've prestiged at least once in, including Call of Duty 4: Modern Warfare, World At War, Modern Warfare 2, and Black Ops on the Xbox 360 and PS3.



Regretfully, we have no way of tracking global user rank on previous PC and Wii versions of these titles and will be unable to reward prestige tokens on those platforms for previous prestiges.

Yeah definitely don't worry about prestiging again. As long as you have prestiged once you are fine.
