Fresh off of a 10 million unit milestone, Mr. Call of Duty 4 himself, fourzerotwo just announced that this weekend, beginning Friday, June 6th, Infinity Ward will be answering Bungie's recent shenanigans with their own CoD4 double XP weekend. Even better, the double XP fun will be enabled for ALL online playlists. W00t! Fourzerotwo also mentioned that they've recently tweaked the map rotation, lessening the frequency of Variety Map Pack maps and giving every map (new and old) the same odds of being selected. Now run along kids and have a happy double XP weekend!
