Stamin-Up

Stamin-Up is a Perk-a-Cola featured in the Zombies game mode. It was introduced along with PhD Flopper on the map Ascension. It returns in Call of the Dead, Shangri-La, Moon, Green Run, Buried, Origins, Shadows of Evil, The Giant, Der Eisendrache, Zetsubou No Shima, Gorod Krovi, Revelations, Voyage of Despair, IX, Blood of the Dead, Classified, Dead of the Night, Ancient Evil, Alpha Omega, Tag Der Toten, and Die Maschine, and is also available via Der Wunderfizz in the remastered versions of Nacht der Untoten, Verrückt, Shi No Numa, and Kino der Toten.

It has two effects, one which is the standard version of the perk Marathon from multiplayer, which gives the player twice the amount of sprint endurance. The other effect is identical to the perk Lightweight from multiplayer, giving a 7% speed increase. The color for this perk is yellow/cheddar, and the icon is a man running at a high speed.
