Mountain Dew is debuting a beverage early next year that is not a soda or an energy drink, but will be placed with the latter in stores. “Game Fuel (not to be confused with the powdered G Fuel), a specially concocted refreshment that Mountain Dew is calling ‘the first drink made by gamers, for gamers.' It’s essentially an evolution of some of the limited edition varieties of the past,” according to Forbes.
