Battlefield 3 has already moved 5 million units, making it quite a popular title. That’s one reason why EA is looking to release as much DLC as possible for their military shooter. Specially marked Dr.Pepper bottles include a code that lets you unlock one of seven prizes. Including 5 dog tags, a multiplayer skin, and a PS3 Home Avatar. Redeem codes here to get your exclusive wares and make other players even more jealous when you kill them. For those averse to carbonated beverages, Dr.Pepper will let you get one of the downloads for free, though it will require signing up for another account you don’t want.
