Halo fans hoping to level up their soldiers more expeditiously in November's Halo 4 can pick up Mountain Dew and Doritos products to earn double experience points, parent company PepsiCo announced today.
Beginning October 15, players who purchase Mountain Dew's special Game Fuel soft drink (at right) and specially marked Doritos products can begin entering codes through the promotion's website.
More information on the promotion can be found at the official website. Halo 4 launches worldwide on November 6 exclusively for the Xbox 360. It is a direct sequel to 2007's Halo 3, and is the first numbered entry in the series developed at 343 Industries.
[CORRECTION] An earlier version of this story indicated gamers could customize their weapon loadouts through the promotion's website. In fact, players can only customize their arsenals through the Xbox 360 itself. GameSpot regrets the error.
