Next month Activision will launch a new US promotion with PepsiCo's Mountain Dew and Doritos, rewarding purchasers with extra XP points for Call of Duty: Modern Warfare 3.
Starting on October 10, gamers who buy the snacks will be able to redeem alphanumeric codes found on the products for slots of "double XP time" in the multiplayer games.
"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," said Activision's chief marketing officer Tim Ellis.
Buying a larger bottle of Mountain Dew will give gamers more double XP time, and combining that purchases with Doritos crisps will add an extra 15 minutes. There is a limitation of 24 hours of double XP play for each gamer.
"Dew fans have been clamouring 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," Brett O'Brien , Mountain Dew VP of marketing added.
"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."
Activision recently won a court case over the use of the domain.
