How quickly do you want to reach Prestige in Call of Duty: Modern Warfare 3? If you want to take advantage of a never-ending stream of double XP (amongst other things), you'll want to grab some Mountain Dew. Two "Game Fuel" flavors are coming back, and in a unique promotion with Activision, purchasing a bottle will give you access to double experience time.

The "Rank Up Your Game with Double XP" promotion will begin in October, giving fans a chance to stock up on codes before the game's November launch. Both citrus-cherry and tropical flavors of Game Fuel will unlock double XP time. If you can't stand Mountain Dew, there is an alternative: the XP promotion also extends to Doritos tortilla chips, through the "Power of One" program.

"DEW fans have been clamoring for the return of Mountain Dew Game Fuel, so we wanted to really fire them up with a partnership that gets to the core of what DEW is all about," Mountain Dew VP of marketing Brett O'Brien said in a press release. "With this partnership we get to make sure that Mountain Dew fuels both the fans and their Call of Duty gameplay while they play Modern Warfare 3."

"For many of our gamers, Call of Duty and Mountain Dew go hand in hand, and together we wanted to deliver gamers a one-of-a-kind program around the epic Modern Warfare 3 multiplayer," Activision's chief marketing officer Tim Ellis added.
