Mule Kick

Mule Kick is a Perk-a-Cola that is featured in the game mode Zombies and Cyborg Rising. It was introduced in the Call of Duty: Black Ops Zombies map Moon. It allows the player to carry three weapons at once. It costs 4000 points to purchase, making it tied with Widow's Wine for the most expensive Perk-a-Cola. When purchased, the player will not see any effect except for the symbol appearing on their HUD. When the player goes to buy their next weapon, the prompt will still state that taking it will replace the currently selected weapon, but in reality it will take its place in the third slot. The color of this perk is dark green (although the color of the drink is dark red) and the icon is three pistols, one behind the other from bottom to top.

If a player is downed whilst this perk is in effect, or if a Space Monkey succeeds in removing it in Ascension, the player will lose the perk, and as a result, the third weapon slot.
