Buy Mnt Dew and Doritios, get double XP in Modern Warfare 3

Activision has partnered with PepsiCo, the makers of many a fine softdrink and various Frito-Lay chips, to provide Modern Warfare 3 players with double XP for purchasing specially marked products.

Codes contained on Mtn Dew and Doritos will, upon entering, provide double XP to the player for various allotments of time.

According to G4, here's how it works out: Purchase a 20 oz. bottle of Mnt Dew or a 12-pack or the even the Walmart-exclusive 20-pack and you will accrue 15, 45 and 90 minutes of double XP, respectively.

Rewards for combo purchases of Mnt Dew and Doritos will also be provided.

Each player can enter up to 24-hours total of XP codes, so gorging on sugar drinks and fattening chips will not do you any good past the 24-hour mark, unless you are intentionally trying to develop diabetes and spare tire around your beltline.

Codes can be entered starting October 10, which should give you plenty of time to rack up 24-hours worth of double XP before the game launches on November 8.
