Perk-a-Cola machines first appeared in Call of Duty: World at War's Zombies mode, and Quick Revive was one of the original perks players could buy with points earned in a match. Each machine played its own short musical jingle in the style of a vintage radio soda commercial, turning a simple purchase into a memorable moment. As Zombies expanded through the Black Ops games, the Quick Revive tune stayed closely associated with getting teammates up quickly, and clips of it now circulate widely among longtime fans online.
