Two of ATL's finest - Outkast's Big Boi and B.o.B - have crossed over into the video game world and teamed up with Electronic Arts' new action game, Army of TWO: The Devil's Cartel. To celebrate the game's release, they've combined forces to put out a new single, "Double or Nothing," the video for which you can watch above. Next week, XXL will get a chance to sit down with the guys and bring you an exclusive interview, so keep your eyes peeled for that.
