If you answered yes, then head on over to your nearest Walmart on November 7th at 8pm. Assuming your Walmart is participating, a tournament is being held there and winners of said tourney will win a copy of Modern Warfare 3. Adding to the stereotype that gamers love Mountain Dew, there are prizes in every one of the specially marked 20 packs of soda which will give you double experience points for 90 minute stretches at a time. That should help you get those unlocks quicker!
Load up on the Mountain Dew; get to your local Walmart; and get that edge on all of the other players who will undoubtedly be wishing they had it instead!
