Juggernog is a Perk-a-Cola featured in Call of Duty: World at War, Call of Duty: Black Ops, Call of Duty: Black Ops II, and Call of Duty: Black Ops III in the game mode Zombies. It was first introduced in the map Verrückt. It increases the player's health from 100 to 250, allowing them to withstand more hits before going down, making it an invaluable perk. It is generally considered one of the most important perks, whether one is playing solo or co-op, so players should prioritise purchasing it as soon as possible.
