Activision is getting into the Halloween spirit and offering you double XP in either of the last two Call of Duty games.
Play either Modern Warfare 2 or Black Ops from today (October 28th) to November 1st and score double the XP you would have yesterday. But why would you want to? So you can Prestige faster – duh. Erm, but why? In Modern Warfare 3 you will be able to purchase tokens in the Prestige Shop and essentially the more you Prestige the more you can get.
But watch the video below for a better explanation than I could ever give.
