The Masterkey Shotgun is an attachment used in Call of Duty: Black Ops Nazi Zombies. It is only found on the Pack-a-Punched AUG.
Overview[]
Being on the upgraded AUG, the Masterkey is a one of a kind attachment, like the grenade launcher for the M16 and MTAR . It is a one-hit kill for zombies up to about Round 17 and Round 20 for short range kills, while being a one-hit kill for Hellhounds up to about Round 25. It is effective at medium to close range and is best to use before it loses its one-hit kill ability. Many players also tend to use it if they run out of ammo for the AUG.
