Since there is no PhD Flopper machine on the map, you might wonder how to obtain this perk on the new map that is released with Season One Reloaded ofCall of Duty: Black Ops 6, Citadelle des Morts. The only way you would think of is to get it from the Der Wunderfizz machine that appears after round 25, which is quite a ways in.

However, there is actually an Easter egg you can complete to get your hands on PhD Flopper. It’s fairly short and actually fun to do. All it requires is finding three bottles inside the castle and using some bartending skills to initiate a bartending experience for all the zombies.
