Perk-a-Cola

Perks-a-Cola machines are fictional vending machines found in the Zombie levels Verrückt, Shi No Numa, and Der Riese. Each drink gives the player an added perk to help them survive. Three of the four perks are based on Second-Tier perks, the last one is a modification of the perk Last Stand.

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

- Juggernog Jingle

Juggernog is one of the four perk-a-cola perks in the Zombie maps. Juggernog increases your health, meaning that it takes more than 2 zombie slashes to down you. This actually increases it to about 6 slashes, which is very important in most scenarios such as during double-digit levels. According to the machine, the nog is made with real eggs and the catch-phrase is "Take a tug on that sweet, sweet Jugg." This is also the only Perk-a-cola machine not shown in the trailer. This perk costs 2500 points to buy. Judging by the fact that it is made with eggs and it is sweet (according to the jingle) it most likely tastes like eggnog. In Verrückt it is in the starting room with German weapons and in Der Riese the perk is on the left of the bridge and near the Bouncing Betty spawn. When the player is buying the perk, be careful as there are two windows next to the machine and many players get ambushed.

Quick Revive Soda
"Whenever things, been draggin you down, grabs you by the hair and pulls 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

Quick revive soda is one of the four Perk-a-Cola perks. The soda makes the player revive other players about 4X faster. As said by the machine, it's ice cold. Also, it's the only Perk-a-Cola machine not based off the tier 2 perks from multiplayer. It is essential in later levels when people are going to be downed INCREDIBLY often and reviving team-mates is crucial in zombie infested environments marked as "No-man's land". This perk costs 1500 points to buy, making it the least costly of the four. In Der Riese, the machine is located right of the Bowie Knife buy-point and near the cave's entrance, and in Verrückt it is in the starting room with American weapons. It is a modified version of Last Stand. Many players have noticed that if two teammates get downed next to each other they have been able to revive them both at the same time.

According to the characters (see Shi No Numa/quotes), this perk tastes like fish, delighting Takeo and angering Dempsey. What Nikolai and Richtofen think of it isn't known, but ask whether they want to help the others.

Double Tap Root Beer
"Cowboys can't shoot slow (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

The third perk, Double Tap Root Beer, makes all of your weapons shoot faster. It is based on the multiplayer perk Double Tap. Unlike most, this is the most common Perk-a-cola to get, but also one of the most useless. It increases rate of fire and Bouncing Betty speed like "Double Tap", however most weapons are at the peak of their ROF (Rate of fire). This perk costs 2000 points to buy. Judging by its name, it tastes like Root Beer. In Der Riese, the perk machine is on the right of the bridge if you are facing away from the Pack-A-Punch machine and is on the left balcony next to the bouncing betties in Verrückt.

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

Speed Cola is based off the perk "Sleight of Hand" and is incredibly useful in later levels where reloading an LMG takes a long time. It also allows you to put up barriers even faster, but the time between individual boards is longer to balance it out. This, combined with every other perk, will ultimately lead to success. This perk costs 3000 points to buy, making it the most expensive of all perk a colas to purchase. Judging by the name, it tastes like Coca-Cola or Pepsi. The machine is located in the room between the right balcony and the kitchen in Verrückt and in the middle of the map and next to the FG-42 in Der Riese.

Amm-O-Matic
The Amm-O-Matic is an unused 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. The stairway is visible on the Der Riese Map, somewhere near Juggernog, but it seems that the idea was scrapped at the last second by Treyarch. Judging by its name, "Amm-O", it probably had something to do with the players' weapons' ammo. This could have possibly been a perk similar to Bandolier or a larger magazine.

This could have been a new machine like the pack-a-punch machine becuse in der riese a player can now upgrade a weapons ammo for 4500 which only works for weapons bought of the wall. The Amm-O-matic could have been a machine that would uprade a weapons ammo.

Trivia

 * In the Verrückt, there is always an advertisement for a Perk-a-cola machine near another Perk-A-Cola machine.
 * When downed, you will lose all your perks, which usually leads to people buying Juggernog first, just so they can live as long as possible with the other perks they have.
 * After buying a Perk-a-cola, a small jingle will play. For Juggernog it plays 'reach for Juggernog tonight', for Quick Revive it plays 'you need a little revive', for Double Tap it plays 'reach for the root beer shelf' and for speed cola it plays just the tune with no lyrics.
 * Every Perk-A-Cola machine in Verrückt states that one bottle will cost 10 cents. But in Shi No Numa, the machine states how many points its perk costs. Although in Der Riese, the machines go back to stating that the drink cost 10 cents, while they still cost 1500 to 3000 points.
 * It is unknown why cola machines are in an Asylum deep in Germany, nor why they are also in a swamp in the Pacific (unknown island). However, the idea of soda machines in a factory is at least possible.
 * One of the posters has a picture of a face on it, which could be a member of the Treyarch team.
 * In Verrückt,an on-screen prompt will tell you how much any given perk costs., but in Shi No Numa,a sticker on the machine itself displays the price
 * Unlike in Verruckt and Der Riese, where the vending machines' locations were fixed, the perk-a-cola machines in Shi No Numa will be randomly generated in each of the four huts. This can make obtaining neccesary perks difficult.
 * On Shi No Numa, you can get the achievement or trophy, Perk-a-Holic, for possessing all four perks at the same time.
 * In Shi No Numa after Richtofen says something about a root-beer shelf, when Dempsey gets the same perk-a-cola he might say "Gah. What on earth is a root beer shelf?".
 * The power needs to be manually turned on for the machines to be used in Verruckt and Der Riese while the machines appear on when they spawn in Shi No Numa.
 * Many players believe that "Juggernog" is the most important perk and is the key to surviving longer.
 * Refraining from using any perk-a-cola machine until round 20 in Der Riese will give the player the Trophy/Achievement Perkaholics Anonymous (It could be considered the opposite of its Shi No Numa equivalent, Perk-a-Holic.)
 * If you look at the Perk-a-Cola machine Speed Cola it appears to have a only 3 or 4 left, but in reality it has an unlimited amount.
 * The name "Perk-a-Cola" is a play on the famous brand "Coca-cola."
 * When buying the Double Tap Root Beer, the characters sometimes say things about root beer shelves. For example Tank Dempsey may say "Yeah partner, i'm thirsty." in response to the jingle lyric "Are you thirsty partner?"
 * After your character finishes drinking the bottle, he will burp and throw away the bottle. However, they keep the bottle cap.
 * If you prone under a Perk-A-Cola machine in Der Riese you will get 25 or 30 points for free.This only works on each Perk-A-Cola machine once, and is probably due to people leaving spare change under the machine.
 * Lots of the machines have blood spilt on them and even handprints, making them a bit gruesome. When they play tunes, however, most players feel they bring a brighter side to the game.
 * Sometimes when one of the machines plays it's jingle the same jingle can be heard at the other machines as well.
 * Even though Jugger-Nog is probably the best perk of the four, it costs less than Speed Cola, probably due to the fact that Speed Cola has a more noticeable effect on the player and is most effective on the most popular weapons like the MG42, M1919 and Wunderwaffe DG-2 and their upgraded variants.
 * The real-world equivalents of these drinks are: Eggnog, Coca-Cola, Soda and Root Beer.
 * Some players have to choose whether to upgrade their weapons or buy perks on Der Riese, as both are costly.
 * On Der Riese, Quick Revive is the only perk that cannot be purchased immediately after activating the power, as it is behind a door that has to be bought open. Juggernog, Speed Cola, and Double Tap can all be found after activating the power without having to open any doors. This is unusual because the best perks can be found easily after the power is activated.
 * Some players where hoping for Bandolier and Stopping power to be buyable Perks, addimitedly both would be quite useful.
 * In Shi No Numa, there are a lot of glitches that involve running and jumping into Perk-a-Cola machines, most of which have been patched now.
 * It is possible that these machines are powered by Element 115. Verruckt could have 115 but there is no facts or theories to prove such stuff. If the machines are powered by 115, it can be assumed that the Wunder-waffe DG 2 could have been invented after the events in the asylum.
