Mule Kick

Mule Kick is a Perk-a-Cola machine first seen in the Zombies map, Moon. It allows the player to hold three guns at once, all of which can be Pack-A-Punched. It costs 4,000 points to use, making it the most expensive Perk-a-Cola. When used, the player won't see any effect except for the symbol appearing in their HUD. When they go to buy their next weapon, it will still tell them that taking it will replace their currently selected weapon, but in reality it will take its place in the third slot. Its HUD colour is dark green yet when you drink it it appears light green.

Location
Moon - Outside, near the teleporter to the Receiving Area, and where the AK-74u can be purchased

Achievements
Fully Armed and Operational - In Moon, acquire 3 Pack-A-Punched weapons at the same time.
