Ardent Call of Duty fans and snack-food junkies alike will have the opportunity to customize their Call of Duty: Advanced Warfare experience with exclusive items that can only be obtained by buying Doritos and Mountain Dew.

The newly announced Fuel Up for Battle promotion will see specially marked Mountain Dew and Doritos products include codes that can be redeemed online at dewanddoritos.com. Doing so will unlock cosmetic items for use in Advanced Warfare through the game’s Supply Drops system, which we first heard about when the game’s multiplayer was unveiled earlier this month.

It doesn’t sound as if any of the “exclusive Dew and Doritos in-game gear” included in this promotion will have any material impact on the game; you’ll be earning things like cosmetic helmets, goggles, boots, and exoskeletons, which is good news because–shockingly–not everyone who plays games likes Mountain Dew and Doritos. Rapid Supply rewards will also be available, as will Double XP bonuses which allow you to earn in-game gear more quickly, but it would seem that buying a bottle of Mountain Dew won’t directly put a (virtual) gun in yours hands.

Items available through the promotion–which has only been announced for the United States so far–will be exclusive until February 15, 2015. Redeeming a code will have the added bonus of entering you in a sweepstakes to win an Xbox One.

The promotion officially kicks off on October 6, almost a full month before Advanced Warfare’s release on November 4 (or November 3 if you preorder). This is not the first time Doritos and Mountain Dew have been used to promote games–both came with codes that granted double XP in Halo 4 back in 2012, while buying Doritos earned you a free Ultimate Team pack for Madden NFL 13 earlier that year.

We got our first glimpse of Advanced Warfare’s multiplayer earlier this month, and it looks extremely promising. The game is scheduled to launch on Xbox One, PlayStation 4, Xbox 360, PlayStation 3, and PC, but not Wii U.
