Perk-a-Cola

Perk-a-Colas are a feature that can be found in all Zombies maps, except for Dead Ops Arcade, and the Call of Duty: World at War version of Nacht der Untoten and also Bus Depot. 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 same machines spawn on fixed locations on each map, with the exception of Shi No Numa, Shangri-La, Moon, Nuketown Zombies and Die Rise, where the Perk-a-Cola machines will randomly spawn at a spawn point, with some exceptions. All Perk-a-Cola machines require the power be turned on before they can be used. Exceptions to this are the Black Ops version of Nacht der Untoten with Mule Kick, all maps on solo containing Quick Revive, Shi No Numa, where there is no power switch; TranZit, where they can be powered by a Turbine and purchased, but will not take full effect until the power is turned on; Mob of the Dead, where each Perk-a-Cola machine must be individually powered through Afterlife before it can be used; and Origins, where each Perk-a-Cola machine must first be powered by its corresponding Generator before it can be bought. Except for Mule Kick.

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, or successfully uses Tombstone Soda or Who's Who.

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 250%. Therefore, in order for a player to be downed, it will take four hits (six quick hits when combined with the similar Perma-Perk on TranZit, Die Rise or Buried) instead of only two from normal zombies and Space Monkeys, or five instead of three from Hellhounds, Crawler Zombies and Minions. George A. Romero will down the player in two hits without Juggernog, three hits with it. The perk costs 2500 points, and is considered by many to be the most important perk to acquire. It is located in:

According to the machine, it is made with real eggs. Every character enjoys its taste (with the exception of Nikolai Belinski in Der Riese with a remark about it being the worst vodka he's tasted). All of the characters in Mob of the Dead appear to dislike its taste. It mirrors Juggernaut.

Speed Cola


"Your hands are slow, your movements 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 decreases reload time by 50% and allows barriers to be built 60% faster (except 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. It mirrors Sleight of Hand.

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 the player's revive time by 50% in co-op, and allows the player to revive themselves in solo (in Call of Duty: Black Ops and Call of Duty: Black Ops II) by automatically taking effect when the player goes down, and temporarily granting them Mustang & Sally (Boomhilda in Origins) 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. 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 and ''Call of Duty: Black Ops II. ''Quick Revive is not featured in Mob of the Dead due to the addition of the Afterlife. It is located in:

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) increases the player's fire rate by 25%, and in Call of Duty: Black Ops II also enables bullet weapons to fire two bullets per shot (twice the pellets on shotguns), effectively doubling damage. This can either be a blessing or a curse; while the player can potentially kill zombies faster, the ammo consumption can grow too big 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 further increasing the weapons' lethality. 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.

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. Bring 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 costs 2000 points. Its locations are: According to the characters, it has a sour taste. It mirrors Marathon, Lightweight, and Extreme Conditioning.
 * Near the AK-74u in Ascension, also next to one of the Mystery Box locations.
 * Behind the lighthouse in a small building near the Stakeout in Call of the Dead
 * In any of the rooms below ground in Shangri-La (changes place with Double Tap Root Beer, PhD Flopper and Deadshot Daiquiri)
 * In Tunnel 11 near Semtex in Moon
 * Ground floor of the bar in Town (in TranZit)
 * Outside the bar in a small corner near M14 in Town (in Survival)
 * End of the hedge maze in Buried, near Pack-A-Punch.
 * Can also be obtained in Buried as a persistant upgrade by running through the hedge maze without stopping.
 * In the area to the left of the Church in Borough.
 * By Generator 5 in Origins
 * Also, it's available via Der Wunderfizz orb in Origins if not yet purchased.

Most characters, with the exceptions of the Misty, Marlton, Stuhlinger and Russman, comment on how sour it tastes.

PhD Flopper


"PhD, the night-time scene. PhD, the streets of mean. PhD, the things I have 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 normally 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. It mirrors Lightweight Pro and partially Flak Jacket. 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.
 * Near Lunar Lander Д (nearest to MP5K) in Ascension
 * Under the lighthouse side entrance (near MP5K) in Call of the Dead
 * In any of the rooms below ground in Shangri-La (changes place with Double Tap Root Beer, Stamin-Up and Deadshot Daiquiri)
 * In the bio dome in Moon
 * The Library area (Mob of the Dead spawn area) in Cell Block
 * It is unavailable but can be seen in both Die Rise and Mob of the Dead
 * Visible with Mule Kick in the docks near the Tower Trap in Mob of the Dead
 * Visible on one of the floors when falling down the starting room elevator in Die Rise.
 * Can be obtained in part as a Persistent Upgrade in Buried
 * Can be obtained through Der Wunderfizz orb in Origins

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 sniper rifles). Deadshot Daiquiri was first introduced in Call of the Dead. It costs 1500 points on consoles, and 1000 on PC (as PC does not support auto-aim, giving less benefit of the perk). It is located in:
 * On the lighthouse catwalk next to the zipline in Call of the Dead
 * In any of the rooms below ground in Shangri-La (changes place with Double Tap Root Beer, Stamin-Up and PhD Flopper)
 * Top floor in the laboratories in Moon
 * Roof access room in the Infirmary next to the room with the Uzi and Hellhound wall in Mob of the Dead
 * In the Cafeteria in Cell Block
 * Can be obtained through Der Wunderfizz orb in Origins
 * Out of all the Perks-a-Colas, Deadshot Daiquiri is the only one to hint that it might contain alchohol, and would thus reduce the players' effectiveness. However, the effect is the opposite of what one might expect.

According to the characters, it has a very sweet taste, even resembling yogurt and strawberries to Takeo Masaki and Samantha Maxis (respectively). It mirrors Steady Aim and partially Grip.

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, in 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 not equal, so they say. But some and 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. It partially mirrors Overkill. None of the Green Run Group contemplate on it's taste.
 * In the starting room, next to the M1A1 Carbine in Nacht der Untoten
 * In the first cell block near Thompson in Verrückt
 * In the starting room, near Gewehr 43 in Shi No Numa

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 (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 a somewhat brief period of time. 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, though it can be guessed it has a poor taste from the name and ability alone. It very slightly mirrors Second Chance, in that it allows the player to kill him/herself, though this is the only trait that the two perks share.
 * In the room available after turning on the power in the Power Plant (in TranZit)
 * In the alley leading to Double Tap Root Beer II in Town (Survival only)

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 gap), 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: Its taste and characters' opinions of it are unknown. It has virtually nothing in common with any known multiplayer perk, as no perk exists in multiplayer that could allow someone to spawn a second version of themselves while down, or revive themselves.
 * 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. 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 dependant on the amount of rounds left when reloading. Replacing an almost full clip will produce a very small blast, whereas replacing an empty clip will produce the largest possible blast. It is only found in Mob of the Dead and Origins. It has no jingle beyond the unusual chiming noises all perks make in the map.
 * Is near the above entrance to the Gondola, and is also next to a crafting station.
 * Can be obtained through Der Wunderfizz orb in Origins

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.

As with all perks in Mob of the Dead, the characters use quotes used for all of the other Perk machines, so no-one comments on the taste of the drink (though, obviously, it can be assumed it tastes like cherry). Electric Cherry has no Multiplayer counterpart.

Vulture Aid Elixer
"I was looking for redemption, I was looking for a sign. I was searching for an answer, be it yours or be it mine. I was hoping for some insight, I was looking far too hard. I was searching for the wrong thing, now I don't know where to start! I spy with my little eye, something beginning with V! It's Vulture Aid, and it's not too late! Get Vulture Aid!"

- Vulture Aid Jingle

http://www.youtube.com/watch?v=sq53GYd9IFM Vulture Aid Jingle

Vulture Aid bestows four unique effects to the player. It costs 3000 points. This perk is also necessary to complete either the Richtofen or Maxis side of the easter egg.

When a player has Vulture Aid:


 * They will be able to see perks, wall weapons, places to draw chalk wallbuys, 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 perk partially mirrors both Scavenger and Engineer. No-one comments on it's taste.
 * 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 new machine in Origins 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 from a nearby generator to function properly. As of Origins, the list of perks/object it can produce are:
 * Juggernog
 * Quick Revive
 * Double Tap Root Beer
 * Speed Cola
 * PhD Flopper
 * Stamin-Up
 * Deadshot Daiquiri
 * Mule Kick
 * Electric Cherry
 * Teddy Bear

Amm-O-Matic


Amm-O-Matic is a canceled vending machine in Shi No Numa and 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 games 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. It is not known if it will appear in future projects. 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: Black Ops, 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 showing of 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 eight perks. 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. Tombstone Soda also allows the player to get more than four perks; the player must buy the wanted perks before collecting the tombstone, which gives the player the previously owned perks along with the newly bought ones.

In Die Rise, killing all of the Minions with 100% accuracy (or using the Trample Steams 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 killing a certain number of the Ghosts. The player also acquires all seven perks upon completion of the "Mined Games" easter egg on Buried.

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.

Trivia

 * 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.
 * Bumping into a Perk-a-Cola machine will make the sound of glass bottles clacking against each other.
 * It is impossible to sprint, interact with other utilities and go prone while drinking a perk. The player is free however, to rebuild barriers.
 * The Perk-a-Cola machines are powered by electricity, but require a relay of Element 115 inside to be powered for a purchased drink to take effect.
 * When the player buys the Perk-a-Cola, the jingle is shortened and only its ending can be heard. They play the songs randomly if the player goes near the machines throughout the game.
 * Speed Cola, Stamin-Up, Mule Kick, Tombstone Soda and Electric Cherry are the only machines where the player can actually see the drink in the machine.
 * An unusable Juggernog bottle can be found on the table near the pool in the multiplayer map Villa in 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 the cola in Call of Duty: Black Ops, the third-person animation used seems to be a re-use of the animation for using the radio. The character will put the bottle up to his head and make talking motions.
 * When drinking in the Wii version, the bottle does not come close to the character's lips.
 * 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. Origins kept the new HUD icons upon its release however the other maps retained the old icons.
 * Like in Mob of the Dead, none of the perks play their original jingles. In Origins, simply playing a whistle in it's place (with such a device to make the sound attached to the side of the machines). The whistle varies from machine to machine (from a light train-like whistle for Quick Revive to a deep, bass-like tune for Speed Cola).
