- "Random Perk!"
- — Demonic Announcer
Random Perk Bottle, also known simply as Random Perk, is a Power-Up featured in the Zombies maps Ascension, Call of the Dead, Shangri-La, Moon, Die Rise, Buried, Shadows of Evil, The Giant, Der Eisendrache, Gorod Krovi, Revelations, Blood of the Dead, Classified, Alpha Omega, and Tag der Toten, as well as the gamemodes Zombies Onslaught and Outbreak. It initially appears as a glowing bottle similar to a Perk-a-Cola or Molotov Cocktail. The Random Perk Bottle power-up gives all living players a random perk that appears on the map for free and can be used to exceed the four perk limit.
During Space Monkey rounds in Ascension, monkeys will attempt to destroy the Perk-a-Cola Machines. If all of the monkeys are killed without touching a perk machine, the player will be awarded with a Perk Bottle along with Max Ammo.
In Call of the Dead, the Bottle, alongside a Death Machine or Wunderwaffe DG-2 (depending on if the player has completed Original Characters Trapped), appears if George A. Romero is neutralized with any weapon excluding the Pack-A-Punched V-R11.
In Shangri-La, a Random Perk Bottle is only attainable by allowing a Zombie Monkey to take a Max Ammo power-up. Do note that the power-up must be a Max Ammo originally, as changing to a Max Ammo with the use of another Monkey makes the Bottle not appear. The Random Perk Bottle will appear for a very short time before it switches to another power up in the cycle. Watching the cycle of the power-ups once through makes this significantly easier as the Bottle appears after the same power-up each time. The player should shoot the Monkey just as the power-up before the Random Perk Bottle is about to change.
On Moon, the Random Perk Bottle can be obtained via the Quantum Entanglement Device when thrown near a perk machine. However, a red Random Perk Bottle can also spawn. This is a power-down, and once obtained by either a player or Zombie, it will cause every player to lose a random perk.
In Die Rise, the Random Perk Bottle can be obtained by killing all the Jumping Jacks on their given round with 100% accuracy. This is most commonly done with melee attacks by using the Bowie Knife or Galvaknuckles, though equipment like Claymores and the Trample Steam also contribute. If successful, the last Jumping Jack will drop the power-up alongside a Max Ammo, similar to Space Monkeys.
In Buried, the Random Perk Bottle is obtained by traveling through the haunted mansion and having various Mistresses spawn. They will replace any zombie that is still alive, almost like the round is at a pause. After all the Mistresses that replaced the zombies are killed, the other players must fend from more attacking them until the player in the mansion has left. This can only be done once every 5 rounds. If the player goes back in the mansion at 4 or less, he will only be attacked and the round is still going.
In The Giant, a Random Perk Bottle can drop after linking the teleporter or using it. In addition to perks already on the map, it can also give Deadshot Daiquiri and Stamin-Up (whose machine can become available through an easter egg).
The Random Perk Bottle is available in every Call of Duty: Black Ops III map using the "I'm Feelin Lucky". "On the House", or "Reign Drops" GobbleGum, as well as every Aether Map in Call of Duty: Black Ops 4 using the "Reign Drops" Elixir.
In Call of Duty: Black Ops Cold War, the Random Perk Bottle appears simply as "Random Perk", now taking on the form of a soda can rather than a bottle. During Zombies Onslaught, the last Special/Elite enemy killed during a surge will drop a Random Perk, while in Outbreak, it can be obtained by eliminating a Horde Patrol that can sometimes appear somewhere on the maps.
- The Bottle is one of several ways to exceed the four perk limit. The others include: Focusing Stone, completing Richtofen's Grand Scheme, throwing a QED near a perk machine, exploiting Tombstone Soda by obtaining perks from the tombstone drop, completing High Maintenance, completing Mined Games, and collecting perks from Der Wunderfizz using empty perk bottles.
- It is possible to obtain all of the Perks on a map if the player obtains the Random Perk Bottle enough times.
- In Solo, the Random Perk Bottle will not award the player any more Quick Revives once the machine has disappeared, even if the player has all other perks, except in Die Rise and Buried. Also, acquiring a Quick Revive from the Bottle counts towards the limit of three Quick Revives.
- Players can lose their perks if they go down after completing High Maintenance, but not after Mined Games.
- In Call of Duty: Black Ops II, if the player picks up a Random Perk Bottle while having all perks available, Richtofen will laugh at the player.
- In Origins, a new variant of the random perk bottle is introduced called the Empty Perk Bottle.
