Here Are Some Perk-A-Cola's Which Nearly Made It Into Black Ops Zombies, But Never Quite Did. So It Could Mean We Might See Them In The Future. Maybe The Next Call Of Duty Treyarch Develop.

Pronaide
Pronaide is a cut perk from the Call of Duty: Black Ops Zombie map Ascension, similar to Tufbrew. It is never mentioned by name, with the only remnants of the perk being sound files under the name perk_pronaid. Richtofen mentions the fact that it makes the player prone faster. It can also be assumed that this perk was an early version of PhD Flopper, because when its effects and Tufbrew's are combined it produces an effect similar to PhD Flopper.

Tufbrew
Tufbrew is a cut perk-a-cola that was going to appear in Ascension. The only proof that it exists are in the character sound files with 'perk_tufbrew' in the name. Dempsey's sound file is the only one that mentions the perk by name. One possible theory for this perk's function is that it reduced player flinching when hit, similar to Hardened Pro. Other theories include that it let the player rip through a horde of zombies when he/she gets surrounded. It could also could have had an effect similar to Stopping Power, increasing bullet damage. Yet another theory is that it prevented grenade damage, similar to Flak Jacket. This is likely as if this perk and Pronaide are combined the effects are similar to PhD Flopper. The "brew" ending suggests its some kind of beer-based drink.

Amm-O-Matic
The Amm-O-Matic was going to make an appearance in both Shi No Numa and Der Riese, but was removed at the last minute for unknown reasons. There are many claims that it can be found in a secret area on both maps, but these claims have been proven false by many people who have scoured every last inch of both maps and have not found it. There is much speculation as to where it was going to appear, but no one has been able to find where it was supposed to be. It is still a mystery as to why Treyarch removed it from two different maps at the last second. The Amm-O-Matic is proven to give Max Ammo to the player using it. Bits of audio in the Call of Duty: World at War game files can be found that relate to the Amm-O-Matic.

Candolier
Candolier is a cut Perk-a-Cola perk that is coded into the PC files of Black Ops Zombies. Not much is currently known about Candolier, but it is most likely going to be the same function as the perk Bandolier from Call of Duty 4: Modern Warfare and Call of Duty: World at War by giving the player the ability to carry extra magazines. Its color is light green, and its symbol is a showing of a row of bullets, implying the idea of carrying extra ammo upon the perk being bought and used. It most likely replaced by the Max Ammo power-up. This perk has a similar function to Amm-O-Matic, another cut perk, since both give the player ammunition.
