Perk-a-Cola

Perk-a-Colas 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).

The machines spawn on fixed locations on each map, save for Shi No Numa, Shangri-La, Moon, Nuketown Zombies, Die Rise, Shadows of Evil,The Giant and Zetsubou No Shima, where the Perk-a-Cola machines 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.

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, or has the Aftertaste GobbleGum in effect.

The map Zetsubou No Shima introduces a feature where utilities and doorways can be covered up in/blocked by webbing, created by spiders. Perk-a-Colas have the ability to be covered by the webs, and also have the ability to be covered by webs at the start of the match just like GobbleGum machines, although only some of the perk machines will be covered in webs. To get rid of webbing on anything, hold the "use" button when the prompt shows up after going up to the covered object.

Juggernog


"When you need some help to get by, something to make you feel strong. Reach for Juggernog tonight, sugar seduction delight! When you need to feel big and strong, reach for Juggernog tonight!"

- Juggernog Jingle

http://www.youtube.com/watch?v=qUmeV-yKyhQ Juggernog Jingle

Juggernog increases the player's health to either 200% or 250%; depending on what type of zombie attacking it could be either. 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. Juggernog costs 2500 points and is generally considered by many players to be the most important perk to acquire, so one should prioritize acquiring it as soon as possible, whether solo or co-op. It is located in:

According to the machine, it is made with real eggs. Most of the characters enjoys its taste, the exceptions being Nikolai Belinski in Der Riese with a remark about it being the strangest vodka he's ever tasted and the characters in Mob of the Dead. It mirrors the Juggernaut perk.

Quick Revive


"When everything's, been draggin' you down, grabbed you by the hair and pulled you to the ground, if you wanna get up, you need a little revive. If you wanna get up... YOU NEED A LITTLE REVIVE!"

- Quick Revive Jingle

http://www.youtube.com/watch?v=JsEXfK-nD9I Quick Revive Jingle

Quick Revive decreases a player's revive time by 50% 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 others 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. To balance this, it is only available three times, except for several Black Ops 2 maps. 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. It is located in:

Speed Cola


"Your hands are slow, your movement's sluggish, your lack of speed, just brings you anguish. Just take a sip, you will move faster. Just try it now! And speed is mastered! Press those lips against the only one that really moves you. Speed Cola speeds up your life!"

- Speed Cola jingle

http://www.youtube.com/watch?v=x4K9cxGDu50 Speed Cola Jingle

Speed Cola halves reload time and allows barriers to be built 60% faster, although the latter is absent in Black Ops 2. It costs 3000 points. It is located in:

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 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


"Cowboys can't shoot slow or they'll end up below. When they need some help, they reach for the Root beer shelf (Ye-haa) Cowboys can't shoot slow, or they'll end up below, when they need some help, they reach for the Root beer shelf. YA THIRSTY PARTNER!?"

- Double Tap Root Beer Jingle

http://www.youtube.com/watch?v=nGkD-oLsHgo 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 25%, 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. Despite this, it is very 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. It is located in:

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.

PhD Flopper


"PhD, night-time scene. PhD, the streets are mean. PhD, the things I've seen, the good (PhD), the bad, and the in-between (Flopper). When you dive to prone, you are surely gonna own, PhD (Flopper)! When you dive to prone, it's gonna shake ya to the bone, all the zombies gonna groan, 'cause of PhD! PhD, the feelin's growing strong. PhD, so right that it feels wrong. PhD, like the chorus of a song (Flopper). PhD, not short but not too long. Slap your body to the floor, everybody needs some more, of your lovin', your explosive lovin'. When you dive to prone, it's gonna shake ya to the bone, all the zombies gonna groan, cause of PhD! (Flopper)! Damn straight!"

- The jingle of the PhD Flopper.

http://www.youtube.com/watch?v=SIhMQa7y5Fw 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. Its locations are: 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, 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-Min-Up! (x3) When you need some extra runnin', when you need some extra time, when you want to keep on gunnin', when you like a twist of lime. When you need to keep on moving, when you need a get-away, when you need to keep on groovin', when you need that vitamin K, babe, you know you want me! Let's run the extra mile! I'll open your eyes and I'll make you see! I'll make it worth your while! Stamin-up-Min-Up! Sounds like it's Staaaaamin-Up time! Oh yeah, drink it baby. Drink it!"

http://www.youtube.com/watch?v=BNrBQpyjAMs 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. It is also very useful with a light weapon, since the player's movement is significantly faster. It costs 2000 points. Its locations are: According to the characters, it has a sour taste. It mirrors Marathon, Lightweight, and Extreme Conditioning.

Deadshot Daiquiri
"To err is human, to forgive is divine. Well I'm not forgiving, and the error ain't mine! They ain't quite human; least they're not to my eyes. One sip of this and I'll give 'em the shock of their lives! Yeah, we got the guns and we got the bombs! In deadshot heaven, we pop skulls for fun! Zero in baby, zero on that spot, the hot spot baby, give it all you got! So quit complainin', about your bad aimin'! Just try, try again for me! With the headshot power of Deadshot Daiquiri!"

- The jingle of Deadshot Daiquiri.

http://www.youtube.com/watch?v=4gZYNS6ZvJg 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. It is located in: 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 proficencies.

Mule Kick
"Legend tells us of a man, a hero in a tortured land, where Señoritas lived in fear. Their lonely nights in deep despair, he was EL BURRO! (Hee-Haw, Hee-Haw). Across the fields, across the plains. He ran so fast he dodged the rain. He was El Burro! He hurried in to save the day, gun in hand, and thrice they say. He was strong like a Mule, he was stubborn like a Mule, he even kicked like a Mule, El Burro! (El Burro!). A man of equal soul they say. But some men more, it's just the way! He was El Burro! He was EL BURRO! EL BURRO!"

- The jingle of Mule Kick, cut from Moon due to the fact that the machine is in an airless environment. The jingle can be heard in-game at Die Rise

http://www.youtube.com/watch?v=85MG6XVal9I Mule Kick 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 and is located in: 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.

Tombstone Soda


"Rest in pieces, down for the count. No revival, you're bleedin' out. Your epitaph says you died a wealthy man, but you can have it all come back and seal the master plan with Tombstone! It's Tombstone! It's Tombstone! It's Tombstone! Health is drainin' you're on the ropes. Death is waitin', don't lose your hopes. Your will and testament ain't making that much sense, you're listed as the only heir to whom you may bequest. It's Tombstone! It's Tombstone! It's Tombstone! It's Tombstone! Tombstone"

- The Tombstone Soda jingle.

http://www.youtube.com/watch?v=OTkSws_u1Nc 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 in Green Run, and is not available in solo. It costs 2000 points. Its locations are: Its taste and characters' opinions of it are unknown, although Stuhlinger mentions that it "Tastes like liquid shock" using a negative tone. Tombstone is similar to the multiplayer perks Second Chance, Last Stand and to the deathstreak Final Stand.
 * In the room available after turning on the power in the Power Plant (in TranZit)

Who's Who
"I was talkin' to myself just the other day, I was hearin' lots of things I never thought I'd say, but one thing I said really blew my mind (Who's who?) I said I don't know me, but I know you, and if you listen closely we can talk it through, it ain't as simple as we're gonna find (Who's who?) I think I will save you, I think I don't blame you, 'cause I like you and you like me. I was talkin' to myself just the other day, then the bad man came and took me away, I feel bad, but not as bad as me (Get off me, man!) I was talkin' to myself just the other day, (You've got the wrong man!) then the bad man came and took me away, (I'm not that man!) I feel bad, but not as bad as me (Not who I am!) (Who's Who?)"

- Who's Who Jingle

http://www.youtube.com/watch?v=21fl-DQ1U5A 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. Its location is:
 * In one of the elevators in the starting skyscraper in Die Rise

Electric Cherry


Electric Cherry creates a lethal electric shockwave around the player whenever they reload their weapon or when they 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. Using this blast is the easiest way to complete A Burst of Flavor. 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.
 * Is near the above entrance to the Gondola, and is also next to a crafting station in Mob of the Dead.
 * It can only be obtained vía Der Wunderfizz in Origins.
 * It can only be obtained vía Der Wunderfizz in Der Eisendrache
 * On Zetsubou No Shima, it can only be obtained by eating a fruit.
 * It can only be obtained vía Der Wunderfizz in Gorod Krovi

This beverage 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 Elixir

Vulture Aid bestows four unique effects to the player. It costs 3000 points, and is located in the church. This perk is also necessary to complete either the Richtofen or Maxis side of the Mined Games Easter Egg.

When a player has Vulture Aid:


 * They will be able to see perks, wall weapons, pack-a-punch, places to draw chalk weapon outlines, and the Mystery Box through walls over a short distance.


 * Zombies will occasionally drop small packets of ammo or points.

The perk is located in the back of the church near the altar in Buried; where Quick Revive is located in Borough. To enter the church, The Giant must break down the barrier. The characters often comment on their eyesight after consuming the perk. The perk partially mirrors Scavenger, Sitrep, and Engineer.
 * Certain zombies will release a cloud of green gas upon death, which will cause players standing inside it to be ignored by other zombies.
 * Zombies' eyes will glow brighter, making them easier to see and distinguish from perk and weapon locations.

Der Wunderfizz
Der Wunderfizz is a machine in Origins, Der Eisendrache and Gorod Krovi 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.

Widow's Wine
"When you're feeling kinda lonely, and your spouse is kinda dead, you feel like curling up with someone, in your empty little bed. There is danger around the corner, (CORNER!) And your love life's in decline, (DECLIIINNNEE!) You'll no longer be a martyr, with a little Widow's Wine (x3). With a little Widow's Wine you're mine... with Widow's Wine, you're mine!"

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, 2 at a time by starting a new round similarly to frag grenades and Semtexes, or 1 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.
 * Located in the rift, next to the portal which leads between the Canal and the Rift in Shadows of Evil.
 * Only obtainable via Der Wunderfizz in Der Eisendrache and Gorod Krovi.
 * Can be obtained for free after defeating the Giant Spider in Zetsubou No Shima.

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.

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 does.

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 Minions 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, or Unquenchable GobbleGums to obtain more than four perks.

Trivia

 * The original four perk machines are based on old soft drink vending machines. Juggernog resembles an old Coca-Cola machine, Speed Cola resembles an old 7up machine, Quick Revive resembles an old Pepsi 5 cent machine, and Double Tap resembles an old 6 cent 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. This is a joke as to how a quarter can sometimes be found under a vending machine.
 * In Shadows of Evil, The Giant, Der Eisendrache, and Zetsubou No Shima going prone in front of the perk machines will give 100 points.
 * On Shadows of Evil and Der Eisendrache, this method will not work for Stamin-Up; it is unknown whether this was intentional or merely an oversight. However in Gorod Krovi, it is possible to acquire the points, they are on the back-right corner of the machine (A location that was inaccessible in the aforementioned maps).
 * The amount of points that the player will get by going to prone in front of perks is not affected by Double Points.
 * Two of the machines on The Giant don't work properly when going prone in front of them, the machine near the Trip Mine wallbuy has the points on the right side of the machine, and the machine near Teleporter B has the points on the other side (The back of the machine) - the perk can also be bought from that side.
 * Only four perk machines will give 100 points on Zetsubou No Shima; both of the machines dropped by cargo plane, the one connecting Spawn and Lab A has the points on the right side of the machine, at an awkward angle, the one by the ICR-1 wall-buy behind Lab B, and the one in the main bunker.
 * 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'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 hand print 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.
