Stamin-Up

"Stamin-Up-Up-Up (x3) When you need some extra lovin', when you need some extra time, when you want to keep on gunnin', when I can risk it out. When you need to keep on moving, when you need a get-away, when you need to keep on groovin', when you need that vitamin K, babe, you know you want me! Let's run the extra mile! I'll open your eyes and I'll make you see! I'll make it worth your while! Stamin-Up! Sounds like it's Staaaaamin-Up time! Oh yeah, drink it baby. Drink it!"

- The jingle of Stamin-Up

Stamin-Up is a Perk-a-Cola perk new to Nazi Zombies, along with PhD Flopper, that is exclusive to the maps Ascension and Call of the Dead. It increases the player's movement speed and sprint duration, being a cross between the perks Lightweight and Marathon. It also gives the effect of Scout pro, decreasing your weapon draw time. It is located near the AK-74u, towards one of the Lunar Lander launch pads and Claymores.

The cost of this perk is 2000 points. This perk is most useful when the player will be running around the map either as their strategy or if they are in danger and being chased by a massive horde of zombies. Alternatively it is good when attempting to defend more than one Perk-A-Cola machine during a space monkey round, particularly if the player is playing on their own or in a small team or if one is trying to avoid George A. Romero. This is effective because Call of the Dead and Ascension are the 2 biggest maps in the game so it lets you go around faster.

Location

 * Ascension - Located past the gates to the left of the upper spawn door. It is in the back of the alleyway past the door (1000 points) leading to the launch pad, next to a spawn point of the Mystery Box.
 * Call of the Dead - Behind the lighthouse and over an ice glacier.

Trivia

 * The perk's name is a play on words of 7-Up, the popular soda, and the word 'stamina'
 * According to in game characters, Stamin-Up has a sour taste.
 * Even though the perk machine says that it is available in multiple colors (including purple, blue, red, orange, yellow, and green, coincidentally all the colors of every other available perk), you can only receive the yellow colored drink.
 * The shape for the Stamin-Up perk machine looks like the shape of the removed perk machine Amm-O-Matic. This has not been confirmed.
