Halo 3 is officially one of the fastest selling games in history, passing the 1 million mark for pre-orders over a month and a half before the September 25th release day. The only game that has sold faster than this is the most recent installment in the Halo series, Halo 2, with 1.5 million pre-orders before launch day. Halo 3 could easily surpass that, and Microsoft/Bungie couldn't be happier. All this popularity is putting Halo 3 on the fast lane to more time in the marketing spotlight than the most recent Simpsons movie. Mountain Dew will be making a special version of it's drink for the Master Chief, which will be known for it's "invigorating blast of citrus cherry flavor" and "added caffeine for maximum intensity". Pontiac will be making a special version of it's G6 SUV, and will be hosting several "Gamer Garage" events. And that's not all. At this point, we'll be able to see Halo 3 memorabilia from Doritos, Burger King, Comcast, and even the gas station 7-11.
