In the long history of Call of Duty Zombies, there has been a mixture of good, bad, and truly overpowered Wonder Weapons. Designed to be the most powerful weapons on their respective maps, the guns often meet the expectations of players - though not always. The original Ray Gun was there at the beginning, and while it is still around in the most recent Zombies maps, there have been a few dozen Wonder Weapons added to Treyarch games since its inception. When Call of Duty Zombies first began, the mode was incredibly simple, with only a single Wonder Weapon available to acquire.
