Treyarch added Mule Kick to all Call of Duty: Black Ops Zombies maps on September 27th 2011 (October 11th on PC). Players must be online or playing co-op for it to show up on all Zombies maps except Moon, as the Perk is already in the map.
The Mule Kick machine has a large, bizarre shape with a red, white, and green paint job. The machine is on a white pedestal. On the front of the machine are red painted dots and ammo belts can be seen, and a sombrero, moustache and two crossed ammo belts can be seen on the red dispenser with the words "Uno mas!!" at the bottom of it. On the left of that are 6 empty bottle compartments aligned vertically. At the top is a quote that says "Mule Kick" and a small price that quotes "10¢" on the right of it. Above that is a circular sign with the Mule Kick icon on it.
Fully Armed and Operational (25 / Bronze Trophy ) - In Moon, acquire 3 Pack-a-Punched weapons at the same time.

- It is tied with Widow's Wine for the most expensive Perk-A-Cola, at 4000 points.
- According to Dempsey, Mule Kick tastes like beer, but Takeo states that it tastes like regular cola, making it a different taste for all the characters. In Origins, it tastes like soda pop to Dempsey.
- The perk's name is taken from the alcoholic mixer Mule Kick.
- There is a picture at the front of the machine that shows a sombrero, a mustache and a bandolier as if to take shape of a human form.
- On the machine, the machine has the two words "Uno Mas!" This means "One More!" in Spanish, referencing to how the drink gives the player "one more" gun slot.
- In Call of Duty Black Ops, the perk's icon on the neck of the bottle depicts a sombero, a mustache, and a bandolier. However in Call of Duty: Black Ops II the perk's official icon is pictured.
- In Zombies mode, the perk depicts three M1911s, while in Cyborg Rising it depicts three G18s.
Call of Duty: Black Ops
- The player will not get 25 points for going prone in front of Mule Kick in Der Riese, unlike other Perk-a-Cola machines.

Call of Duty: Black Ops II
- In Die Rise, all of the character's quotes when drinking Mule Kick is yelling Mule Kick.
- In Mob of the Dead, both Mule Kick and PhD Flopper are unobtainable Easter eggs. However, the player(s) can buy these Perks in the Grief map, Cell Block.
- Upon completion of Edward Richtofen's side of Mined Games, the player will receive a variant of Mule Kick that will allow the player to carry four weapons.
- When Mule Kick is bought in Cell Block, a phasing variant of its jingle can be heard. It sounds similar to the background whistle during the line "A hero in a tortured land."
