PhD Flopper (WWZ)

"PhD Flopper... In a hospital... How original."

- Wayne Truman, after buying PhD Flopper

PhD Flopper is a Perk-a-Cola featured in the Zombies game mode. It was introduced along with Stamin-Up on the map Ascension and returns in Call of the Dead, Shangri-La, Moon, Die Rise and Mob of the Dead (Grief only)

It first appears in the World War Z storyline on the map, Breakout Zone

Effects
PhD Flopper completely negates self-inflicted damage; however, the player will still groan and suffer temporary movement reduction when falling down from an elevated area. Another feature of this perk is that when players dive to prone from a height from which they would normally take damage, a 7.5 meter radius mini-nuke is created upon landing.

The "nuke" is very powerful, with a maximum of 5000 damage at the center of the blast radius, and can kill zombies with 1 hit up to approximately round 20. Between rounds 20-30, PhD Flopper will begin to make crawlers, and on rounds beyond 30, zombies will retain their legs even in the center of the blast

Locations
Breakout Zone-Found in the Operating Theatre in The Main Building.

DLC Locations TBA when DLC is released.
