Kept fresh by frequent new releases, COD best summed up its universal appeal in an old commercial for Black Ops titled "There's a Soldier in All of Us." The commercial shows regular out-of-shape citizens in street clothes and even a fast-food-worker's uniform, all ecstatically blowing things up. But it also shows the late Kobe Bryant doing the same. And that—from fast food employee to NBA star—shows the reach of this super satisfying game. Check out this cool collection and get your COD wallpaper today!
