This perk is most likely another name for the previously mentioned cut Perk-a-Cola 'Boom Juice'. It's highly probable the perk was reworked into 'PhD Flopper'. According to the quotes this perk would allow the player to make an explosion. There are 4 cut quotes mentioning this perk. Sorry for the self promo but here is a link to a video with all audio lines mentioned: BoomJuiceĪ cut Perk-a-Cola that was planned for the Zombie map 'Ascension'. In addition, Pack-A-Punched versions of the Kiparis, Stoner63, Skorpion, and WA2000 exist in the game's files.
(Note: The purple blood is custom textures and NOT apart of the gun) However, the Pack-A-Punched version of the weapon, the 'Red Mist' is fully present and working, adding an attached flamethrower. It does very little damage, has no firing sound and cannot be Pack-A-Punched. For some reason, the AK-47 is present in Zombies mode, but normally inaccessible and only half-finished.
