Mule Kick is a Perk-a-Cola that appears in every single Call of Duty: Black Ops map as long as you're connected to the internet (including World at War remastered maps), and without internet conncection this perk will only appear on Moon, on pc however if you have the patch you can have Mule kick on every map even if you don't have internet connection. This perk also returns on Black Ops 2 zombies on the new map Die Rise . The effect gives the player an additional weapon slot bringing the total number of weapons a player can hold to three. If the player gets downed with Mule kick while having a 3rd gun, one of his guns will get lost so the perk is a bit risky.This perk is currently the most expensive perk, and the third most expensive thing available for purchase, at the high price of 4,000 points. The Mule Kick's icon is three white pistols along side each other with a dark green background.
In Origins, you can find it in the excavation site, right across from the staffs. You can also obtain it through the Der Wunderfizz machine. To get to the excavation site, find the granophone, put it on the table, and you should see the stairs forming. Go to the top platform, jump to the platform across from it, and then drop onto the floor with Mule Kick.
Legend tells us of a man, a hero in a tortured land, where Señoritas lived in fear. Their lonely nights in deep despair, he was EL BURRO! (Hee-Haw, Hee-Haw). Across the fields, across the plains. He ran so fast he dodged the rain. He was El Burro! He hurried in to save the day, gun in hand, and thrice they say. He was strong like a Mule, he was stubborn like a Mule, he even kicked like a Mule, El Burro! (El Burro!). A man not equal, so they say. But some and more, it's just the way! He was El Burro! He was EL BURRO! EL BURRO! (Hee-Haw, Hee-Haw).
Mule Kick will give you three guns, but if you're on final stand mode you will lose your third weapon.
Mule Kick does not appear anywhere in the iPod zombies app.
Mule kick is the third most expensive item in any Zombies map, the second being Pack-A-Punch, along with Galvaknuckles as the first.
In the original Black Ops no jingle plays when you purchase the perk, even though the song is in the files, the jingle can be heard in both Black Ops 2 and Black Ops 3 on all the maps it can be purchased on.
