Mountain Dew, Doritos, and Halo 4- it’s a match made in heaven. As the launch of Halo 4 looms ever closer, PepsiCo doesn’t want you to forget to pick up some junk food in addition to the newest Halo game. Starting October 15, specially marked Mountain Dew and Doritos products will come with codes redeemable for “Double XP” multiplayer matches at DEWXP.com. Once entered, the matches can be transferred to your Xbox Live Gamertag and can be used in game once Halo 4 launches November 6th. In addition to Double XP, the ‘citrus cherry’ flavor of Mountain Dew- Game Fuel -will be making a limited time re-appearance, and players can enter to win other prizes like an Xbox 360 or Xbox Live Gold membership. And if you don’t win, you still get to enjoy the delicious taste of Mountain Dew, Doritos, and imminent diabetes.
