1. You buy PHD flopper for 2000. 2. Jump off a high platform and it wont hurt you a bit and will cause a massive explosion. 3. PHD flopper reduces the chance of you dieing when you jump off of a high platform. Thanks P.S Roadboy98
PhD Flopper made its first appearance in Call of Duty: Black Ops on the Zombie map Ascension, which you can buy on Black Ops from the First Strike Map Pack for 1200 Microsoft Points. Along with PhD Flopper, Stamin-Up made its first appearance in Ascension.
No, all the trolls out there will say it is possible. It is NOT possible to get PHD flopper on Die Rise. Source: Common Sense
Run the zombies in a circle around the lander near PhD Flopper, and use PhD when possible to conserve ammo.
The PhD flopper is a power up on Ascension and Call of the Dead that makes you take no fall damage and if you run jump and crouch it makes an explosion that kills zombies
PHD Flopper and Stamin-up
juggernog, speed cola, quick revive, mule kick, double tap rootbeer, stamin up, phd flopper, deadshot,
i say Juggernog is better than Double tap and Quick Revive. Speed cola is 2nd place. Stamin-up is better than Phd-flopper.
It means Dr. Of philosophy.
