PhD, like the chorus of a song. PhD, not short but not too long. Slap your body to the floor, everybody needs some more, of your lovin', your explosive lovin'.

PhD Flopper is a perk as that first appeared in Ascension. The perk's color is purple, it cost 2000 points. The perk acts similar to the Flak Jacket perk from multiplayer, allowing you to resist explosions and such. The second part of the name, Flopper, comes from the fact that whe you dive, or go prone, mid-air off a high surface, you create a mini nuke that kills nearby zombies. It also allows you to be immune to any self-inflicted damage. This means you resist falling damage & grenade damage including the Matryoshka Dolls, Ray Gun, and the M72 LAW, and China Lake.


  • The name is a reference and a parody of Dr. Pepper, as PhD and Dr are both medical abbreviations.
  • It is apparently made from prunes.
  • There will be no explosion upon diving to prone in low gravity on Moon.
