Perk-a-Cola

Perk-a-Colas (known as Perk Altars in the Chaos Story and Demonic Fountains in Call of Duty: Vanguard) are a feature that can be found in all Zombies maps, except for Dead Ops Arcade, Bus Depot, and the Call of Duty: World at War version of Nacht der Untoten. They also appear in Call of Duty Online's Cyborg Rising game mode. Each drink gives the player a perk to help them survive and fend off the zombie hordes. Some are based off of perks found in multiplayer (such as Juggernog and Speed Cola mirroring Juggernaut and Sleight of Hand respectively). Throughout most of their appearances, each Perk-a-Cola had a unique cost, however this changes in Call of Duty: Black Ops Cold War where the costs are unified and dependent on how many perks the player has. This cost is increased by 500 points for every perk the player has, with the first perk costing 2500 points and the final perk costing 7000 points.
The Perks spawn on fixed locations on each map, except for Shi No Numa, Shangri-La, Moon, Nuketown Zombies, Die Rise, Shadows of Evil, The Giant, Zetsubou No Shima, and Dead of the Night where the Perks will randomly spawn at a spawn point, with some exceptions. All Perk-a-Cola machines require that the power be turned on before they can be used, unless there is no power switch in the map. Exceptions to this are all maps from Black Ops onwards on solo containing Quick Revive; Mob of the Dead, where each Perk-a-Cola machine must be individually powered through Afterlife before it can be used; Origins, where each Perk-a-Cola machine must first be powered by its corresponding 115 Generator before it can be bought; and Shadows of Evil, where the system is the same as in Mob of the Dead, only activating perks individually through the Beast. Additionally, in TranZit, a Perk-a-Cola machine can be activated prior to turning on the power through use of a Turbine. In the Chaos Story maps, the Perk Altars can be used immediately upon discovery. In Black Ops Cold War, some Perk machines are already being powered by an external generator and thus do not require Power to be turned on. In Vanguard, the Demonic Fountains are not powered by any source of power, and can be drank immediately upon discovery.
In the Aether Story, Group 935 was involved in making a lot of the Perk-a-Colas, particularly Juggernog, Quick Revive, Speed Cola, Double Tap, Deadshot Daiquiri and Mule Kick. According to the timeline, Doctor Monty helped Group 935 make the perks, and he himself has a factory that manufactures perks. Upon studying Group 935's elixir research, the Ascension group also develops the perks PhD Flopper and Stamin-Up. In the Chaos Story, the Perk Altars are one of many supernatural objects that appear during a Sentinel Trial with the intent of helping those undertaking the trial. In the Dark Aether Saga, the Perk-a-Cola machines were created by Kazimir Zykov for the use of Requiem. The Demonic Fountains are supposedly created in the Dark Aether itself with the use of "demon blood".
If a player is downed, they will lose all the perks they have purchased and will have to buy them again, unless they have obtained the Focusing Stone, completed the Richtofen's Grand Scheme, completed Maxis' or Richtofen's side of Mined Games, successfully uses Tombstone Soda or Who's Who, Aftertaste or Near Death Experience GobbleGum, or if a teammate as acquired Near Death Experience or Phoenix Up GobbleGums. In Call of Duty: Black Ops 4 the player will lose 2 perks, and if in co-op gradually lose the other two depending on how long they have until they bleed out. A similar system is featured in Call of Duty: Black Ops Cold War, where the player will lose one perk if their perk count is three or lower, or they will lose all but three perks if they have four or more. Any remaining perks after the initial perk loss will slowly decay until the player is revived, though this can be changed with the usage of Tombstone Soda or Healing Aura at Tier 5. Tombstone is always the first perk to be lost, making it an excellent perk to save more important perks. Quick Revive is the last perk to be lost, with the exception of its Tier 5 ability, which instantly removes the perk.
==Juggernog==
 Juggernog Jingle 
Juggernog increases the player's health from 100 to 250. In order for a player to be downed it will therefore require five hits instead of only two (three in Black Ops III) from normal zombies, Zombie Monkeys, Shrieker Zombies, the Avogadro and Space Monkeys, six instead of three from Hellhounds and Crawler Zombies, eight instead of four from Jumping Jacks, and four instead of two from Brutus. George A. Romero will down the player in two hits without Juggernog and three hits with it. The Panzersoldat has the most powerful melee attack out of all zombies with a devastating 125 damage; the Panzersoldat will down the player in one hit without Juggernog and two hits with Juggernog. It costs 2500 points and is generally considered by many players to be the most important perk to acquire, so one should prioritize purchasing it as soon as possible, regardless of solo or co-op.
According to the machine, it is made with real eggs. While most of the characters state that they enjoy the taste, Ultimis Nikolai Belinski in Der Riese, Mob of the Dead cast and all of Primis in The Giant will remark in less positive light about the taste. It mirrors the Juggernaut multiplayer perk.

==Quick Revive==
 Quick Revive Jingle 
Quick Revive halves a player's revive time in co-op, and allows the player to revive themselves on solo (in Call of Duty: Black Ops, Call of Duty: Black Ops II, and Call of Duty: Black Ops III) by automatically taking effect when the player goes down, and temporarily granting them that level's starting pistols upgrade, or whatever upgrades available if the player has an appropriate gun that can be used when down during the ten seconds it takes to be revived. It does not require power on Solo, but is only available three times, except for several Black Ops 2 maps. After Call of Duty: Black Ops 4, Quick Revive no longer automatically revives the player when they are downed in Solo. Instead, by default, it allows the player to revive teammates quicker in co-op, and it shortens the delay between taking damage and regenerating health. It costs 1500 points in co-op in all games and in solo in Call of Duty: World at War, and 500 in solo Call of Duty: Black Ops, Call of Duty: Black Ops II, and Call of Duty: Black Ops III. Quick Revive is not featured in Mob of the Dead due to the addition of the Afterlife.
According to characters, it tastes like fish. Every character, aside from Takeo Masaki, greatly dislikes its taste. It partially mirrors Second Chance, Last Stand and Final Stand.

==Speed Cola==
 Speed Cola Jingle 
Speed Cola halves reload time and allows barriers to be built 60% faster, although the latter effect is absent in Black Ops 2. It costs 3000 points. In Call of Duty Black Ops Cold War, Speed Cola was nerfed, with reload and barrier building speed being dropped to 15%, though it can be upgraded to 30% at tier 3 still making it half the speed as it was previously.
According to Richtofen, the main ingredient may rot the consumer's mind, and according to Nikolai Belinski, it is spicy. Every character enjoys its taste. From a quote in Buried made by Marlton Johnson it appears that it does not contain sugar or dairy, but in Origins "Tank" Dempsey says that he can't remember the last time he's tasted sugar and that his basic rations are barely edible. It mirrors Sleight of Hand.

==Double Tap Root Beer==
 Double Tap Root Beer Jingle 
Double Tap Root Beer (Double Tap II in Call of Duty: Black Ops II and Call of Duty: Black Ops III) increases the player's fire rate by 33%, and in Call of Duty: Black Ops II and Call of Duty: Black Ops III also enables bullet weapons to fire two bullets per shot (twice the pellets on shotguns), effectively doubling damage. This can potentially be a double-edged sword; while the player can potentially kill zombies faster, the ammo consumption can be detrimental on weapons with an already high rate of fire and substantially decrease accuracy. It is therefore extremely useful on weapons with low rates of fire, such as pump-action shotguns, bolt-action rifles, BAR, HK21 etc. where the ammo will not drain uncontrollably but the weapon is even more lethal. This perk costs 2000 points.
According to "Tank" Dempsey, it tastes chewy. Every character either comments on its effect(s) or its jingle. It mirrors the perk from multiplayer, Double Tap, and the Rapid Fire attachment.

Double Tap II machine BOII.png|Double Tap II Root Beer machine.
==PhD Flopper==
 PhD Flopper Jingle 
PhD Flopper grants the player immunity against explosive and falling damage; this includes cooking grenades for too long, as well enabling the player to trigger a powerful blast by diving to prone from a height that would otherwise damage them. PhD Flopper was first introduced in Ascension. This perk is very useful if the player uses explosive weapons a lot, particularly the Ray Gun, Scavenger and Mustang and Sally. Its explosive dive ability can also be used as a stand-alone up to approximately round 20. It costs 2000 points.
According to the characters, it is incredibly chewy (even suggesting it can be chewed before swallowed outright), and according to Robert Englund, it is made of chemicals. The characters, such as Samantha Maxis, comment on it tasting of prunes. Takeo Masaki comments how he is allergic to prunes, so this is his least favorite perk. It mirrors Lightweight Pro, Dead Silence Pro and partially Flak Jacket.

==Stamin-Up==
 Stamin-Up Jingle 
Stamin-Up affects the player's overall mobility, as it increases movement speed by 7% and sprint duration by 100%. Stamin-Up was first introduced in Ascension. It can greatly assist the player in large maps such as Call of the Dead to get to other places faster, as well as with heavy weaponry, such as light machine guns and launchers, to allow the player more mobility, or it can also be used to escape an incoming swarm. It is also very useful with a light weapon, since the player's movement is significantly faster. It costs 2000 points.
According to the characters, it has a sour taste. It mirrors Marathon, Lightweight, and Extreme Conditioning.

StaminUp BOCW.png|Stamin-Up machine after Black Ops Cold War.
==Deadshot Daiquiri==
 Deadshot Daiquiri Jingle 
Deadshot Daiquiri increases hip fire accuracy by 35%, reduces recoil on all weapons (most notably on sniper rifles), removes idle sway on sniper rifles, and adjusts the Aim Assist to target the zombies' heads instead of their torsos (except on wonder weapons and explosive weapons). Deadshot Daiquiri was first introduced in Call of the Dead. It costs 1500 points on consoles, and 1000 on PC as the latter does not support auto-aim, giving less benefit of the perk. Within Call of Duty: Black Ops Cold War, Deadshot Daiquiri was given a visual makeover with a new rock theme with the effects changed to instead entirely remove scope sway on all weaponry rather than just on sniper rifles alongside changing the Aim Assist to target "Critical locations" rather than just heads, as targets may have critical locations that differ from their head.
According to the characters, it has a very sweet taste, even resembling yogurt and strawberries to Takeo Masaki and Samantha Maxis, respectively. It somewhat mirrors Steady Aim, and Scout, while also resembling the Kick, Breath and Stability proficiencies.

==Mule Kick==
 Mule Kick's Jingle 
Mule Kick grants the player a third weapon slot, so as to be able to carry a third gun (when purchased off the wall or from the Mystery Box), however, if the player goes down and loses the perk, they will lose the third weapons slot and whichever weapon was being held in that slot. Mule Kick was first introduced in Moon, but on September 27th, 2011, it was made available on all maps in Call of Duty: Black Ops (except Dead Ops Arcade) via a hotfix. It costs 4000 points.
According to "Tank" Dempsey, it tastes like beer, while according to Takeo Masaki, it tastes like cola, suggesting that it may taste different depending on the individual. It partially mirrors Overkill.
Mule Kick Machine Render.png|Mule Kick machine between Black Ops and Black Ops III.
Mule Kick Machine Mauer der Toten BOCW.png|Mule Kick machine in Black Ops Cold War.
==Tombstone Soda==
 Tombstone Soda Jingle 
Tombstone Soda allows the player to kill themselves while down, and recover their equipment via a Tombstone power-up if they get to it in time. This gives the player all of their weapons, equipment and perks back, with the exception of Tombstone itself. As the player goes down, the player can hold the 'use' button to die prematurely. When the round ends, the player will respawn and be able to collect the power-up, which is shaped like a tombstone, left in the same spot that the player went down. Only the player who killed themselves can collect the power-up, and the power-up will disappear after 90 seconds. Being revived will cancel the perks effects, and the player will have to re-acquire all their perks again. Tombstone Soda only appears on Green Run in Call of Duty: Black Ops II, and is not available in solo. It costs 2000 points. In Call of Duty: Black Ops Cold War, Tombstone was given the additional benefit of allowing the player to become a "shadow" upon downing and earning the opportunity to revive themselves, similar to Who's Who. In Call of Duty: Modern Warfare III, the function of Tombstone changed once again, though still relatively similar to its original counterpart. Due to the open world system, Tombstone still allows the player to drop a "tombstone" upon death, but the player will only have access to it on the next game, allowing them to regain lost points and loot. 
Its taste and characters' opinions of it are unknown, although Stuhlinger mentions that it "Tastes like liquid chalk" using a negative tone. Tombstone is similar to the multiplayer perks Second Chance, Last Stand and to the deathstreak Final Stand.

==Who's Who==
 Who's Who Jingle 
Who's Who allows the player to take control of a doppleganger when they go down, allowing them to revive themselves or even keep zombies busy so others can revive the original character. The doppelganger spawns near the original character, has altered vision and is equipped with only an M1911. If the player succeeds in reviving oneself, they will retain all weapons, equipment and perks aside from Who's Who. In addition, dying in a way that the player cannot be revived, such as falling down the gaps between buildings, Who's Who will respawn the player without having to wait for the round's end. It currently only appears in Die Rise. It costs 2000 points.
Who's Who machine BOII.png|Who's Who machine in Black Ops II.
==Electric Cherry==
Electric Cherry creates a lethal electric shockwave around the player whenever they reload their weapon or when they go down. It costs 2000 points to purchase. The color for this perk is light blue (although the color of the drink is cherry red), and the icon is a red cherry. The effect of the perks is dependent on the amount of rounds left when reloading. Replacing an almost full magazine will produce a very small blast, whereas replacing an empty magazine will produce the largest possible reload blast. When the player dies, they will create a significantly larger explosion capable of killing several zombies, similarly to the death streaks Dead Man's Hand and Martyrdom. The perk is found in Mob of the Dead, Origins, Zetsubou No Shima, Der Eisendrache, and Gorod Krovi. It has no jingle beyond the unusual chiming noises all perks make in the map. It is very useful in close quarter maps such as Mob of the Dead.
The Electric Cherry is necessary to complete the A Burst of Flavor achievement/trophy, requiring killing ten zombies within the given radius of one entire shockwave.
In Mob of the Dead, when the player approaches the Electric Cherry machine, it makes an unusual chiming noise but does not have a known perk jingle.

==Vulture Aid==
 Vulture Aid Jingle 
Vulture Aid bestows four unique effects to the player. It costs 3000 points, and is located in the church in Buried. This perk is also necessary to complete either the Richtofen or Maxis side of the Mined Games Easter Egg.
Vulture Aid Elixir Machine.png|Vulture Aid machine in Black Ops II.
==Der Wunderfizz==
Der Wunderfizz is a machine in Origins, Der Eisendrache, Gorod Krovi, and Revelations that provides the player a random perk bottle for 1500 points. It will relocate itself to one of several locations if used a certain amount of times, similar to the Mystery Box. It requires power to function properly. In order to know its actual location, the player will have to look at the sky and look for a lightning strike. It functions much differently after Call of Duty: Black Ops Cold War, where it allows the player to select which perks they would like to purchase from the machine in rapid succession.

DerWunderfizz Transparent BOCW.png|Der Wunderfizz machine after Black Ops Cold War.
==Widow's Wine==
 Widow's Wine Jingle 
Widow's Wine gives the player a special type of grenade similar to the Semtex which creates a spider web when it detonates, as well as increasing melee damage, changing the sound for the default knife, adding a green trail to the default knife, and causing melee attacks to have a random chance to ensnare zombies without consuming grenade ammo. The web slows zombies down momentarily and deals some damage to the zombies, but none to the player. The player will automatically detonate the grenades in their pocket when hurt by zombies, enabling them to make a quick escape when they would normally be cornered. It is important to note that being slapped by zombies will cause the player's Widow's Wine Grenade ammo to deplete without throwing one, and can also kill the last zombie of a round if they are trying to keep it alive. In this situation, it is preferable to throw all remaining grenades out of map to avoid accidentally detonating them. The player can replenish grenades all at once with a Max Ammo, two at a time by starting a new round similarly to frag grenades and Semtexes, or one at a time by killing zombies ensnared in a web, which have a random chance of creating a blue drop that looks like the spider on the perk icon. It is possible to melee zombies in an attempt to ensnare them and kill them for additional grenades without consuming any, or when the player is out of them.

==Elemental Pop==
 Elemental Pop Jingle 
Elemental Pop is a Perk-a-Cola introduced in Call of Duty: Black Ops Cold War, which when acquired gives every bullet fired by the player a small chance to apply a random base Ammo Mod effect at the base tier.
ElementalPopMachine BOCW.png|Elemental Pop machine in Black Ops Cold War, Modern Warfare III and Black Ops 6.
==Death Perception==
 Death Perception Jingle 
Death Perception gives the player an orange outline of nearby enemies through walls, similar to a thermal optic. Any nearby enemies off screen will be highlighted by small white arrows on the HUD denoting their location relative to the player.
Death Perception Machine BOCW.png|Death Perception machine in Black Ops Cold War and Modern Warfare III.
==PhD Slider==
 PhD Slider Jingle 
PhD Slider is the successor to previously introduced Perk-a-Cola PhD Flopper. It will allow the player to generate an explosive burst of Aetherium energy upon sliding into a zombie, with the size and damage of the burst being dependent on the distance the player slid before impacting a target.
PhD Slider Machine BOCW.png|PhD Slider machine in Black Ops Cold War.
==Melee Macchiato==
 Melee Macchiato Jingle 
Melee Macchiato is a Perk-a-Cola introduced in Call of Duty: Black Ops 6, which gives the player a damage buff to their melee weapons. It also turns their gunbutt into fists allowing for higher damage.
Melee Macchiato Machine BO6.png|Melee Macchiato machine in Black Ops 6.
==Call of Duty: Black Ops 4==
Call of Duty: Black Ops 4 Zombies completely reworks the classic Perk system.
In the Aether Story maps, there are four machines within the game corresponding to four distinct purchasing models, beverage names, and so on. They are Brew, Cola, Soda, and Tonic. However, in the Chaos Story, there are four unique statues corresponding to four deities from mythologies ( of Irish folklore, of ancient Egypt, of classical mythology, and of Norse mythology). Each machine/statue starts at a pre-determined area on each map and resides there permanently, but the Perk it holds can be modified in-game in Create-a-Class. Every machine/statue functions the same except for the Tonic machine in Aether and the Odin statue in Chaos, which enables the player to get a modifier for the Perk they get from it. This functions as an additional effect. To receive this effect, the player must have all four Perks. In addition to the modifier, when all 4 Perks are bought, the player's reload will increase. There are currently 18 Perks in-game to chose from.

==Call of Duty: Vanguard==
In Call of Duty: Vanguard, the Perks are now known as Demonic Fountains, featuring new Perks which are similar to older, previously featured Perk-a-Colas. Perk Fountains feature 4 Tier Upgrades with the base Tier being free and every subsequent Tier having an increased cost: 2500 Essences for Tier 2, 5000 for Tier 3, and 7500 for Tier 4. When downed, the player will keep the Perk but will lose one Tier.
===List of Demonic Fountains===
====Aethereal Haste====
Allows the player to increase their movement speed, similarly to Stamin-Up.
====Demonic Frenzy====
Allows the player to increase their reload speed, similarly to Speed Cola.
====Diabolical Damage====

==Cut Perk-a-Colas==
===Amm-O-Matic===
Amm-O-Matic is a cancelled vending machine in Der Riese. Although it cannot be seen or used in Der Riese, there is a stairway that leads up to it next to another cut perk called Candolier. The stairway is visible, but the player is unable to climb to the top of it. It is located somewhere near the next room to Double Tap. It seems that the idea was scrapped at the last second by Treyarch. Unused sound files that remain on the game's disc confirm that this machine was designed to give the player a Max Ammo upon purchase. The perk cost 10000 points and was only able to be used once. Its color is baby blue, similar to the Quick Revive machine, and its symbol resembles a bullet.
===Candolier===
Candolier is a Perk-a-Cola machine that was originally set to appear in Call of Duty: World at War, but was cut from the game. Not much is known about the machine, but it is most likely going to be the same function as the perk Bandolier from Call of Duty 4 and World at War by giving the player the ability to carry extra ammo. Its color is light green, and its symbol is a row of bullets, implying the idea of carrying extra ammo upon the perk being bought and used. This idea was eventually reimplimented in Call of Duty: Black Ops 4 as the perk Bandolier Bandit.
===Tufbrew===
Tufbrew is a cut Perk-a-Cola referenced in Ascension's game files. The name suggests the perk may have increased the player's strength in other ways than Juggernog would do.
===Pronaide===
Pronaide was a cut perk in Ascension that would make the player go prone faster than normal. It can be assumed it was an early predecessor to PhD Flopper. Not much else is known about the perk.
==Obtaining More than Four Perks==
Starting with the release of Ascension, the maps could contain more than four perks. However, the player can only buy four perks at one time: attempting to buy another when currently owning four will result in failure. To circumvent this, there are a few methods on maps after Ascension to obtain more than four, up to nine perks (with the release of Origins). The most commonplace is the Random Perk Bottle, a power-up that awards every living player with an extra random perk. Also, obtaining the Focusing Stone and completing Richtofen's Grand Scheme will award the player all perks that last until the end of the game. However, despite there being five with the release of Mule Kick in the Call of Duty: Black Ops versions of Verrückt, Shi No Numa, Der Riese, Kino der Toten and "Five", there is no way to obtain more than four.
In Tranzit, players can obtain over four perks by buying any three perks, then buying Tombstone Soda. The player must then down themselves, and "Not Feed the Zombies". After the player respawns, they will have to collect the other two perks they didn't have and buy Tombstone again. The player must be quick, otherwise their tombstone power-up will disappear. On TranZit, this can extremely difficult due to the large distances to travel. The only location to actually obtain enough perks to overcome the limit would be the Town, where Juggernog and Stamin-Up are located (provided the player was downed here so that the Tombstone would spawn here as well, and the player has bought all the other perks).
In Die Rise, killing all of the Jumping Jacks with 100% accuracy (or using the Trample Steam or knifing) during their respective round will award players a free perk bottle. The player is also able to obtain the six perks on the map by completing the easter egg.
In Buried, the player can obtain a free perk bottle by navigating through the Ghost's mansion when the lights are on, the lights should come back on after three to five rounds of the previous navigation. The player also acquires all seven perks upon completion of the "Mined Games" easter egg on Buried. Another way to get another free perk is to get a Ballistic Knife from the Mystery Box and then go to the Saloon. Once the player is at the Saloon, the player must then look on the floor for a white line. When they see the white line they must then be behind it and then shoot a knife at the dartboard. If the player's knife lands in the middle, they will get 100 points and then the piano behind them will play. This means that they triggered an Easter Egg. Go to the mansion, and then when you're at the entrance near the hedge maze, go to the opening to the mansion on the other side. Once the player is inside again, they will see the Ghost playing the piano, go to the right side of the piano and you will see an indicator saying to hold the action button and tip 10 points. Once you tip 10 points, you will get a free perk. You'll have 90 seconds to get a free perk using this method, if the player fails to get the perk, he/she must wait the next round and then attempt it again. Also, if the player can't shoot their knife at the dartboard in the middle, they must wait for the next round and try it again.
In Origins, the player can dig in orange spots if they have the Golden Shovel and are in Zombie Blood. Digging up an orange dig spot rewards the player with an empty perk bottle, which adds an extra perk slot. However, only four empty perk bottles can be acquired through digging through orange bone piles, the last perk should be Double Tap, for it comes free with one of the rewards at the stone chests at Generators 1 and 6.
In Call of Duty: Black Ops III Zombies, the player can use the Perkaholic, On The House, Soda Fountain, or Unquenchable GobbleGums to obtain more than four perks. With Soda Fountain, a player will obtain a free Perk-a-Cola with purchase of another Perk-a-Cola, provided that player does not have all existing Perk-a-Cola effects on the map. More than 4 perks can be obtained on Der Eisendrache, Zetsubou No Shima and Gorod Krovi by completing their respective Easter Eggs. More perks can be also be obtained on Zetsubou No Shima, Gorod Krovi and Revelations through completing challenges. Additionally, perks can be obtained on Zetsubou No Shima by growing fruit plants, or receiving a Blue Perk.Bottle Power-up from a plant. On Revelations, the player can obtain a random Perk by wall-running and jumping across a sequence of walls in the Der Eisendrache area of the map, when anti-gravity has been activated. Each player in the game can do this one time each, allowing every player to receive all 9 perks (providing they also complete the challenge on the map to get their ninth perk), without the use of GobbleGums.
In Call of Duty: Black Ops 4, there are 2 ways to get more perks in the map IX. The first involves completing challenges. After completing a certain amount of challenges, the player will be rewarded with a random Perk Vapor. The second involves gathering a Viking Helmet, Sword, and Mug and placing it on the corpse of a Viking found in the Odin Temple. Afterwards, the player must have Wraith Fire equipped in order to throw it on the corpse from the Zeus temple. When done correctly, the corpse should remain lit on fire. The player must then wait 7 rounds before a specific power-up drop will spawn which has a resemblance to Odin. When picking up the drop, the player will be automatically given a random perk that will stack on top of the pre-selected 4 perks (and the extra 5th perk from the challenge, if gained).
In Call of Duty: Black Ops Cold War, however, the Perk-limit is removed entirely, allowing the player to get more than 4 perks by default. This continues in Call of Duty: Vanguard, where the player can purchase all five Demonic Fountains, as well as in Call of Duty: Modern Warfare III and Call of Duty: Black Ops 6.
==Trivia==
*The original four perk machines are based on old soft drink vending machines. Juggernog resembles a Vendo 44 Coca-Cola machine, Speed Cola resembles a VMC 81 7up machine, Quick Revive resembles a Heintz Gullwing Pepsi-Cola auto vending cooler, and Double Tap resembles a VMC 27A Coca-Cola machine.
*In Der Riese and Origins, going prone in front of the perk machines will give the player 25 points, although visually showing as 20 or 30 in Call of Duty: World at War, referring to finding change under vending machines in real life.
**In Call of Duty: Black Ops III and Call of Duty: Black Ops Cold War, going prone in front of the perk machines will give 100 points. This feature is known as "Loose Change" in Black Ops Cold War.
***On Shadows of Evil this method is harder to perform for Stamin-Up, as the machine is on a raised floor - it does work if the player goes prone before the machine and then crawls into it.
***On Die Maschine, it is harder to retrieve the Loose Change from Quick Revive because it is in the water of the Pond area. It will work if the player goes prone from an angle where they are on the wooden platform the perk is sitting on.
***The amount of points that the player will get by going to prone in front of perks is not affected by Double Points, except for in Call of Duty: Black Ops Cold War, where the player will receive 200 essence.
***Mule Kick doesn't give 100 points on Zetsubou No Shima due to the machine being partially submerged in water.
*Bumping into a Perk-a-Cola machine will make the sound of glass bottles clacking against each other.
*An unusable Juggernog bottle can be found on the table near the pool in the multiplayer map Villa in the Wii version of Call of Duty: Black Ops.
*An unusable Juggernog, Double Tap, Speed Cola and two Quick Revive bottles can be found in the glass case just in front of the Quick Revive vending machine in Kino der Toten.
*In Samantha Maxis's destroyed room, there are soda bottles for Juggernog, Quick Revive, Speed Cola and Double Tap Root Beer on the floor.
*When drinking in the Wii and iOS version, the bottle does not come close to the character's lips, however, in the iOS version, the bottle comes slightly closer.
*All Perk-a-Cola machines except for Mule Kick in Call of Duty: Black Ops have a bloody handprint on them.
*In Mob of the Dead, all the Perk-a-Colas and the Pack-a-Punch, with the exception of Electric Cherry, have a strange static effect on them.
*In Mob of the Dead, the perk machines play a heavily distorted version of their jingles, resembling a bell toll.
*As of the June 27, 2013 update, all Perk-a-Colas in Mob of the Dead and Buried have an updated HUD icon.
*In the map Metro, there are unusable perk bottles that can be found beside the yellow hut to the right of the red entrance (where the "A" flag spawns). Inside there is a glass cabinet that holds Tombstone, Quick Revive, Deadshot Daiquiri, Stamin-Up, and Juggernog.
*In Dr Monty's Factory, various Perk-a-Cola bottles can be seen on conveyor belts in the background. This is most visible on the sides of the screen.
**This is due to the fact that Monty helped create the Perk-a-Colas.
**In an Easter Egg on Revelations, Dr. Monty will sing an early version of the jingles. To hear these, the player must have both Widow's Wine and Electric Cherry and knife one of the original four perk machines.
*Unlike other perk machines, when standing next to the Quick Revive machine it will sometimes play glitched and garbled parts of its jingle.
*In Call of Duty: Black Ops 4, the Vapors dispensed by the Perk Altars are stated to smell extremely bad. All characters, with the exception of Stanton Shaw, hate the smells. 
**According to Scarlett Rhodes, they smell like paint thinner.
**Bruno Delacroix states they smell like "gunpowder, dirt, blood, and screams".
*In Call of Duty: Black Ops Cold War, all of the perk machines have changes to them, ranging from minor color and material differences, to a full remake of the machine.
*While inside of the Dark Aether, all of the perk jingles are modified. They sound similar to that of a bent record, with a slowed, deeper sounding jingle. A similar effect is also applied to Pack-a-Punch.
*In Call of Duty: Vanguard, the Operators will comment that the Demonic Fountains taste terrible, and is frequently compared to urine.
**However, the Elder Gods seem to revere the demon blood of the Fountains as "nectar", according to Bellekar.
**Thomas Bolt will oddly, in a quote while drinking a Demonic Fountain, compare the flavor to that of "real maple syrup".
**Snoop Dogg compares the flavor to "cognac mixed with puke".
*A goblet for the Demonic Fountains first appeared in intel for Black Ops Cold War, where it was dubbed the "Archaic Goblet".
