The Call of Duty: Black Ops Cold War community has long debated the ingredients within the popular perk-o-colas. While each perk has a distinct style and assumed flavor, only recently have fans been able to read the ingredient list. When one Call of Duty: Black Ops Cold War fan unveiled the ingredients, some fans were surprised at what was found inside.

Call of Duty: Black Ops Cold War continued the Zombies tradition and added in a modern redesign to the perk-o-cola system. These new canned versions include a nutrition chart along with a list of ingredients along the side. While players have always assumed that the drinks were carbonated, there are some unusual additions that give these beverages their unique tastes.

In a photo captured by _ExoMute_, the Call of Duty: Black Ops Cold War player got up-close and personal with a can of perk-o-cola. The can is a stylized version of quick revive, and it contains an interesting list of ingredients. According to the can, the drink includes Trench Water, Chicken Broth, Concentrate, Adrenaline, Ammonium Salts, Anchovie Paste, and Feline Urea. Although this list of ingredients is unexpected, some fans expected worse to be within these super-powered cans.

One fan noted in the comments that Tank Dempsey has a famous line regarding this beverage. When he drinks a Call of Duty Zombies perk-o-cola, he describes it as tasting like "cat piss." Considering that cat urine is in the ingredient list, it is not surprising that Dempsey has accurately described this drink's formula for years without knowing.

The drink comes with 150g of fat, 90g of sodium, 125g of carbs but is surprisingly sugar-free. Fans noticed an interesting mark as it contains 10g of "Protien," which is either a typo or the magic energy that grants the drink its unique powers. Call of Duty Zombies fans are sure to recreate this can, and now they know exactly what to put inside it.

Call of Duty Zombie fans have long been fascinated by the unknown contents of each perk-o-cola. Considering that each can has a probable list of ingredients, the code for each drink's flavor may soon be cracked by the game's community. While this one is particularly unappetizing, it is likely the others will have similarly questionable ingredients. Despite fan ambition, it is most likely impossible to add "Protien" into the drink's contents and trigger the magical in-game effects.

Call of Duty: Black Ops Cold War is available on PC, PS4, PS5, Xbox One, and Xbox Series X/S.
