Video Game / Call of Duty: Zombies
aka: Nazi Zombies

Let's be honest: People don't play CoD:WaW to play CoD:WaW; they play it to play Nazi Zombies.
Nervous Nick,

Four batshit insane grunts take on the undead hordes of the Axis. Or replace the grunts with four historical figures from the 1960s, four horror-genre celebrities, four oddball civilians, four gangsters from the 1930s, four alternate universe, somewhat less batshit insane versions of the grunts, or four murderers from the 1940s who somehow managed to survive the apocalypse, possibly less insane but still pretty Crazy Awesome.

Originally a bonus mode in Call of Duty: World at War and a standalone iPhone/iPod Touch/iPad game where you originally play as one of four silent US marines holed up in a wrecked base near an airfield in Nacht der Untoten, Treyarch's Zombies quickly became the true focus of their Downloadable Content seasons. Originally titled Nazi Zombies, the game mode was retitled as simply Zombies (as the characters were no longer fighting just Nazi zombies). Treyarch's Zombies appears in the aforementioned World at War, Call of Duty: Black Ops, Call of Duty: Black Ops II, and Call of Duty: Black Ops III. The game mode functions as an Endless Game in which the game ends whenever you finally fall to the zombies, gathering points from your survival efforts to spend on new weapons, perks, Pack-a-Punch upgrades and the Mystery Box to help you hold out for longer.

Following the surprise success of Nacht der Untoten, Treyarch committed to releasing a Zombies map in every DLC from then on. The second map of World at War featured Corporal "Tank" Dempsey and his squadron of Marines fighting to escape a Nazi sanatorium in Verrückt, before Dempsey gets captured and forced to join up with the equally crazy Nikolai Belinski, Takeo Masaki and Dr. Edward Richtofen to survive a Japanese swamp house in Shi No Numa, and finally a massive Nazi laboratory in Der Riese, where the zombies were created.

2010's Black Ops saw the debut of Kino der Toten, a map in which Richtofen, Dempsey, Nikolai, and Takeo battle the undead in an abandoned Nazi theater. Other on-disc content included "Five", a map in which you play as John F. Kennedy, Richard Nixon, Fidel Castro, and Robert McNamara as they fend off a zombie outbreak in the Pentagon during the Cold War. The DLC season began with Ascension, featuring Richtofen's crew exploring an overrun Soviet cosmodrome and also featuring the first serious hints towards the larger Myth Arc at play. The second map is Call of the Dead, depicting Sarah Michelle Gellar, Danny Trejo, Robert Englund, and Michael Rooker as themselves fighting off legions of zombies commanded by an undead George A. Romero on the set of the director's latest movie. Richtofen's group later starred in Shangri-La, set in a Himalayan jungle, and Moon, which brought the Black Ops story arc to a dramatic season finale.

The formula got a bit of a shake-up for Black Ops II, released in 2012. Now almost every map had smaller game modes within it, with one game mode advancing the storyline. The first map, Green Run, featured a main story mode in TranZit, and introduced a new crew of characters who would become the main focus of Black Ops II and also starred in the first DLC map, Die Rise, set in a pair of crumbling skyscrapers in China. Side stories included the pre-order bonus Nuketown Zombies, and the acclaimed Mob of the Dead, a mystery revolving around four 1940's gangsters trying to escape an overrun Alcatraz Island. The Green Run group returned for Buried, set in an underground western town in Africa, as they seek answers about the mysterious forces at play. Black Ops II came to a conclusion with Origins, an Alternate Universe story depicting Richtofen, Nikolai, Dempsey, and Takeo as World War I soldiers.

Black Ops III, released in 2015, continued to expand the game mode with even larger maps, mechanics, and a much stronger focus on the Story Arc. The first map, Shadows of Evil, starred four survivors battling zombies and Lovecraftian horrors in Morg City, lured in by the words of an even more shady figure. The main story of Black Ops III began with the pre-order bonus map The Giant, a re-master of fan-favorite Der Riese, which starred the alternate Richtofen and crew as they began a quest to save the universe from unspeakable evil. The crew ventured through the DLC maps Der Eisendrache, a Group 935 castle in the Alps; Zetsubou No Shima, a Japanese island on which horrific biological experiments took place; and Gorod Krovi, featuring a war-torn Stalingrad besieged by giant robots and dragons. The Story Arc came to its' conclusion with the final map, Revelations.

In an unprecedented move, in May 2017, Treyarch would release a fifth DLC pack for Black Ops III known as Zombies Chronicles, which contains remastered versions of 8 classic maps: Nacht der Untoten, Verruckt, Shi No Numa, Kino der Toten, Ascension, Shangri-La, Moon and Origins. A tie-in Zombies comic debuted in October 2016 by Dark Horse Comics, revolving around the main cast of Black Ops II, last seen in Buried.

New iterations of Zombies, developed by Sledgehammer Games and Infinity Ward, debuted in Call of Duty: Advanced Warfare, Call Of Duty Infinite Warfare and Call of Duty: WWII. They are unrelated to the Treyarch series, and thus their tropes should go on their respective pages.

The Nazi Zombies story is very complex; it involves practically everything from the Illuminati to the Third Reich to aliens to the works of George A. Romero. Each map contains tons of little Easter eggs only the most observant of players will find and these little clues often play a bigger role later on. The ongoing Story Arc is also mostly played out through increasingly complex Easter eggs while the backstory is told through audio logs. Word of God is mostly averted as Treyarch almost never has anything to say about the story, leaving fans to try to put the pieces together by themselves. The general synopsis can be found here, put together through said audio logs and Easter eggs. And after the conclusion of the series with Revelations, Treyarch made another unprecedented move and released the full timeline with pretty much every question about the lore answered.

Despite the fact it was originally called Nazi Zombie Army, the Zombie Army Trilogy is no relation to this game, being spun out of a Sniper Elite V2 expansion series instead of a Call of Duty one.

Tropes for this game:

  • After the End: The setting of Zombies in Black Ops II, as a result of Richtofen's Grand Plan in "Moon".
  • All the Worlds Are a Stage: Revelations is incredibly fragmented due to the proceeding events, resulting in a number of previous maps "bleeding" into it. This includes Kino Der Toten, Nacht Der Untoten, Mob of The Dead, Shangri-La, Origins, Der Eisendrache, and Verruckt.
  • All Your Powers Combined:
    • On a musical level, the three singers of the Easter egg songs, Elena Siegeman, Clark S. Nova, and Malukah all collaborate with Kevin Sherwood for "Archangel".
  • Authority Equals Asskicking: John F. Kennedy, Richard Nixon, Fidel Castro and Robert McNamara in Five.
  • Abandoned Hospital: "Verrückt". Actually an asylum, though.
  • An Ice Person:
    • Anyone who gets the Winter's Howl gun (which, as the name suggests, freezes zombies).
    • The Ice Staff and it's upgraded form in Origins.
  • And Now for Someone Completely Different: Generally in effect when a new cast is introduced, or new features.
    • "Five" replaces the original four with real-life figures JFK, Fidel Castro, Richard Nixon, and Robert McNamara. A map later, Call of the Dead features the tale of Danny Trejo, Michael Rooker, Robert Englund, and Sarah Michelle Gellar squaring off with a zombified George A. Romero on a movie set.
    • Black Ops II introduces a system where you can build various tools, devices, and weapons, and introduces a new main cast consisting of Action Girl Misty, Insufferable Genius Marlton, Conspiracy Theorist Samuel Stuhlinger, and Russman. Also, Clark S. Nova and Malukah take over music duties from Elena Siegeman until Origins, where they collaborate.
    • Mob of the Dead is a dark, sombre story of four murderous mobsters fighting to escape an overrun Alcatraz in Purgatory.
    • Shadows of Evil is a map based in the 40s, where four people with dark and gruesome pasts end up fighting off the hordes of Cthulhu. And if you complete the Easter Egg in full, Richtofen from Origins comes and takes away the key to saving the world. It is implied Morg City, where SoE takes place exists in another dimension.
  • And the Adventure Continues: The Origins crew gets erased from existence by Dr. Monty at the end of Revelations, only to change his mind the last minute and have them sent back in time as the legendary Primis heroes, effectively repeating the time loop once again.
  • Apocalyptic Log:
    • Radio transmissions in Shi no Numa, experiment records in Der Riese and film reels in Kino Der Toten. When you play by yourself in Kino der Toten, you hear Richtofen making one last note before they're transported to the theatre during the loading screen.
    • This occurs even more so in, Die Rise. Hidden televisions allow you to hear what just has been going on outside the world... and it is not pretty.
  • Artifact Title: By Black Ops, it's safe to say that the zombies aren't Nazis anymore.
  • Arc Number: 115, the number of the chief periodical element that appears throughout the series.
  • Arc Welding: Found in every map.
  • Arc Words:
    • "You must ascend from darkness."
    • "Beware the Doc" and "Teddy is a liar" for Richtofen's arc
    • "Letting go" first shows up in Mob of the Dead and remains a theme for the final three maps. A savvy fan decoded a cypher on the lyric video of "Where Are We Going" that further points to this phrase: "Let go and the beginning will become the end."
  • Ascended Fanfic:
    "It's a little gun, but it has a long barrel, like my college roommate."
  • Arm Cannon: The Russian Mangler in Gorod Krovi has this as a primary weapon. Shooting and breaking it will cause it to go ballistic and sprint after whoever was responsible.
  • The Atoner: In the original timeline (and the canon ending of the split Easter Eggs), Dr. Maxis took control of the Aether and destroyed the Earth in an attempt to find Samantha in Agartha - but failed to find his daughter, having destroyed Earth for nothing. To help create a better future for the universe, the new incarnation of Maxis helps the Origins crew and directs them along their quest in Black Ops III.
  • Ax-Crazy:
    • Richtofen is a crazed scientist who relishes the blood and gore of his battles with the zombies.
    • Samantha, too, as she's not right in the head after spending who knows how long in the hellish Aether controlling zombies that have killed countless people, and presumably meeting entities like the Apothicons.
    • Billy Handsome is a trained killer who is the most eager for blood out of the Mob crew.
  • Badass Boast: More or less all of the characters do this in-game.
    • Richtofen, especially, has one in his theme song for Tranzit, Carrion.
      Lyrics: I was spawned from eternal night, by infernal right, and I need your carrion. Neurons fire when I violate, pupils dilate, and I feel your carrion. I bring doom and defile light, your entire life, will now cease to carry on! I've returned and I'm not alone, never to atone, and forever carry on.
  • Badass Bookworm:
    • Richtofen, an accomplished scientist in his own right who's arguably the central character of the series.
    • Robert McNamara, who often makes accounting jokes while slaughtering zombies.
    • Marlton in Black Ops II, seeing as he's a bespectacled nerd who still manages to slay zombies with the best of them.
  • Back-to-Back Badasses: A variation in an early trailer advertising Nacht der Untoten, it ended with four nameless American soldiers putting their backs together to cover all angles from the approaching zombies.
  • BFG: Excluding the already massive machine guns that you can hip-fire:
    • The Wunderwaffe and the Thundergun.
    • The Jet Gun may not function as well as the Wunderwaffe and Thundergun, but good lord is it big.
    • Introduced first as a power-up in 'FIVE' is the Death Machine, which is the crown jewel of BFGs as it is a fricking minigun!
      • And you can upgrade it too! It becomes the Meat Grinder and holds 550 rounds per 'magazine'... More Dakka anyone?
    • The Paralyser. A gun so big, you can't aim down sights with it (The Thundergun and Jet Gun also cannot aim down sights.) And it is very useful. (Not quite a gun, but who cares?)
    • In Origins, we now have the water cooled MG08. The fact that is is meant to used by two people, in a static position...
    • In Black Ops III, the Gorgon and the SVG-100 are the biggest weapons you can get out of the Mystery Box and both fire massive .50 caliber rounds.
      Kennedy: As Teddy Roosevelt once said: walk lightly and carry a BFG!
  • BFK:
    • The Bowie Knife, which kills most zombies with one strike before round 10.
    • Danny Trejo wields machetes in the Call of the Dead opening cutscene, but not in-game, unfortunately.
  • Big Bad:
    • Richtofen. He swaps bodies with Samantha in Moon to gain control of the zombies, if you carry out his Grand Scheme.
    • Dr. Maxis takes over as the announcer in Buried, if you listen to his commands. If you stick with Richtofen, Dr. Maxis is gone for good, which may or might be the better choice.
    • In the new timeline forged by the Origins crew, Richtofen and Maxis are working together to save the universe from the Apothicons, horrific entities who seek to plunge the universe into destruction by planting Divinium in all dimensions, making them the Big Bad of the entire series. Their chief enforcer is the Shadow Man.
  • Bilingual Bonus: The soldiers in the "Zetsubou No Shima" intro speak only untranslated Japanese.
  • Blood Bath: Richtofen longs to bathe naked... IN YOUR BLOOD!!!
  • The Bluebeard: Nikolai. Subverted in Gorod Krovi, where it's revealed that Nikolai had only one wife that was killed during the war.
  • Boom, Headshot: Not necessary, but gains you the most points (other than knifing - and since zombies will kill you in one or two hits, and knifing zombies can take up to five swings, this isn't recommended) and uses less ammo. However, on the later rounds, people care less about headshots and more on staying alive. However, headshot damage multipliers still help with the staying alive bit.
    • Characters will often brag aloud about their headshots.
    • One of the Perk-A-Cola machines (Deadshot Daiquiri) gives you a perk that adjusts your quick aim to the head instead of the chest.
    • As of Tranzit, it is possible to gain a 'persistent perk' that increases the power of headshots.
    • Ritchtofen does this to his older self in the cutscene of The Giant.
    • Nikolai also does this to his older self in the end of the Easter Egg for Gorod Krovi.
  • Bond One-Liner: All the time. Nikolai makes shitty ones all the time, and then gets a bit confused on the aspect of it being after a kill.
    "You are dead now! But you were dead before! Ah, fuck you!"
    Nikolai again, in Black Ops: "Do you know how to say 'own' in Russian? OWNT!
    Nikolai also seems fairly adept at rhyming: "Nikolai cannot die! Hey, that rhymes!"
  • Breaking the Fourth Wall:
    • In Kino der Toten, one of Dempsey's "Out of Ammo" quotes is:
      Hey, player! Drop the chips and get me some ammo!
    • And then at the start of Ascension, Dempsey may say:
      Hey, Treyarch, can we get a new objective!?
    • Dempsey has more such "Out of Ammo" lines in Shangri-La, right down to outright mentioning when he'll be saying another "Out of Ammo Line".
    • Again with Dempsey.
      Dempsey: Hey, Player. If you looked at your score, you'd see we weren't doin' so well. And it's YOUR FAULT!
    • Also, Richtofen has this to say:
      I'VE BEEN RECOGNIZED BY TREYAR- I mean the Illuminati!
  • Breather Episode:
    • Nuketown is this for Black Ops II, being the only one that doesn't feature an Easter egg, though you get to listen to Richtofen carrying out his scheme on the Moon.
    • Mob of the Dead takes a break from the Maxis/Richtofen arc and doesn't advance the main plot, but it is in no means Lighter and Softer than the other maps.
    • Call of the Dead is largely a love-letter to horror fans with an all-star cast and an original song written for the game by Avenged Sevenfold, and only advances the main plot minimally through the Easter egg.
    • The Giant, the first proper map for Black Ops III, doesn't contain the tragedy found in every other map of the game and is a trip down memory lane with a remaster of Der Riese.
  • Buffy Speak: Nikolai does this in Shangri-La when low on ammo.
    ''I need one of those floaty green ammo container thingys."
  • Butt-Monkey: Robert Englund gets hit in the face by George A. Romero, thumped on the back of the head by Danny Trejo and karate-kicked onto his back by Sarah Michelle Gellar.
  • Call-Back: Revelations 's intro has one too The Giant 's, someone from the original timeline stands before a teleporter from which the younger Richtofen emerges, before standing in front of them. Similar angles and shots are also used, but whereas young Richtofen reacted to his older self by unceremoniously shooting him in the head, he and Maxis hug instead.
  • Calling Your Attacks: Takeo and Dempsey on Moon. Pokemon style, no less.
  • Celebrity Survivor: Call of the Dead features four celebrities as zombie-killers — Sarah Michelle Gellar, Robert Englund, Michael Rooker, and Danny Trejo. And George A. Romero, but he's a boss zombie.
  • Cerebus Syndrome:
    • The intel in Black Ops reveals that Dempsey and company were guinea pigs for the virus, but instead of turning into zombies, they got stronger and healthier, but were inflicted with Laser-Guided Amnesia. Word of God confirmed that Richtofen is Edward from the messages and he lacks the aforementioned amnesia, and he's the one who infected them.
    • One of the funniest Running Gag's of the series has been Nikolai mentioning his love for vodka and his many, many wives. Gorod Krovi reveals that he only ever had one wife, and after she was killed in an air raid, he became a drunk to forget the pain of losing her.
  • Cluster F-Bomb:
  • Combat Resuscitation: Players who take two hits (four if they have Jugger-nog) fall down and need to be picked back up by a teammate. They can still crawl around slowly and attack with pistols, magically gaining a M1911 if they don't.
  • Cool, but Inefficient: Most of the weapons get straight upgrades that are required. However, the MG42, Browning M1919 and the Wunderwaffe get lackluster upgrades. Of course, machine guns are cool in their own way... not to mention the Wunderwaffe. And not to mention necessary - a low rate of fire will kill you on rounds nearing or past 20.
    • Even a friggin' pistol that shoots grenades, an alien Ray Gun, and a bazooka are worse than the machine guns and the Wunderwaffe.
    • Rebalanced in Black Ops, where the machine guns do less damage, allowing SMGs and assault rifles to compete, even at higher rounds.
    • Shows up in Tranzit, where you build a massive Jet Engine that can suck up zombies and rip them to shreds... however is notably weak compared to other Wonder Weapons and lacks their efficiency.
  • Cosmic Horror Story: After the revelation that the Shadow Man in Shadows of Evil is a servant of an eldritch entity bent on destroying our dimension, the story of the series becomes a race to change history and save the Earth from this otherworldly evil. Revelations reveals that the Apothicons, masters of the Shadow Man, are evil entities from the Dark Aether who seek to bring about destruction to all dimensions by planting Divinium in each dimension. Planting it in the original timeline led to its' discovery at Shi No Numa, and eventually Black Ops II in which both Richtofen and Maxis destroyed the Earth after being guided by the Shadow Man. Now, the heroes are tasked with defeating the Shadow Man and the Apothicons and saving the universe from annihilation.
  • Creepy Child: Samantha. Good god, Samantha. She's spent years killing countless people with the zombie hordes and encountering hellish entities from other dimensions, so she's not put together that well once we get to meet her properly.
  • Cruel and Unusual Death: All the zombies end up dying in cruel ways due to the way some wonder weapons and traps work. Of course, it's not like many people care, they're brain-munching zombies!
    • The Electro-Shock Defenses have been a staple since Verruckt, appearing again in all WAW maps and in some Black Ops maps. They return in two maps during Black Ops III.
    • The flogger is as deadly as it is hilarious - zombies who run into it get ragdolled a great distance away.
    • The fire pit in Kino Der Toten is crucial to certain strategies to reach high rounds.
    • In Mob Of The Dead, one trap put in the way towards the Warden's office consists of two fans that gib any zombie that passes through them. The other trap is located in the Cafeteria and rains pure acid onto the zombies.
    • Traps return in Shadows Of Evil as chains hidden in the walls that launch and shred zombies into bits.
    • In Zetsubou No Shima, one trap consists of two precariously held B-17 engines, which lower down and decapitate any zombie that passes through it when activated. The second trap is a turbofan embedded in a wall that sucks zombies in and gibs them on it's rotors.
    • In Gorod Krovi, flinger traps appear in three locations and, well... fling zombies.
    • Most of the Wonder Weapons cause this, as they usually fire things that no one would want to get hit by.
    • The Wunderwaffe electrocutes zombies and chains lightning towards any other zombie in the vicinity.
    • The 31-79JGb215 is a gun that shoots a ray that shrink zombies into rat-sized bobbleheads. Which you can stomp on or just kick away (which is a lot funnier).
    • The Wave Gun causes a zombie's insides to expand and it to float away and eventually explode on a shower of gore.
    • The Sliquifier shoots a liquid that pops zombies into bits and chains similarly to the Wunderwaffe. If shot in the floor, it causes the zombies to slip in hilarious manners.
    • The Apothicon Servant is an organic Eldritch Abomination weapon that shoots black holes that suck in the zombies and crush them.
    • Taken to a new level with the Bows in Der Eisendrache.
      • The Lava bow traps zombies inside small lava graves, which them erupt like a volcano and burn the zombies into a crisp.
      • And then there's the Void Bow. Shooting a charged shot causes a rip in dimensions to open and mini Keeper demons to appear. They then proceed to EAT THE ZOMBIES ALIVE. Lampshaded by Dempsey.
        Dempsey: Owww! That's a BAD way to go!
      • The Storm Bow creates an electrical tornado that grabs and electrocutes zombies. It has enough force to lift them with the electrical charge!
      • The KT-4 in Zetsubou No Shima shoots a liquid that causes spores to grow in the zombies and make them pop.
        Dempsey: GET PLANTED, FLESHSORE!
      • The new Ray Gun in Gorod Krovi has two guns: One that shoots a Paralyzer-like ball, and a Ray Gun Mark III. Firing the Ray Gun into the ball causes it to create a black hole that disintegrates the zombies.
  • Darker and Edgier:
    • Black Ops II is not as lighthearted as the previous games. There are still some wonderful one liners, but in general, many of the situations in the game are not Played for Laughs. Black Ops III goes even darker, as the series becomes an all out Cosmic Horror Story as the heroes race to kill their original counterparts and save the universe from the ancient evil known as the Apothicons.
    • And topping off this trope is Mob of the Dead, the darkest map in the series, with very, very few lines Played for Laughs. In this map, we also have straight up criminals instead of jerkasses and soldiers as protagonists, including Billy Handsome and Sal DeLuca.
    • Buried is incredibly dreary and solemn. It's clear the crew has gone through hell to get here and they spend the entirety of the map in dark, tight spaces, following the orders of unseen people in the hopes of saving the world. No matter who you help, it's heavily implied the four are killed regardless. Either Richtofen has the world as a plaything, only to be trapped in Samuel's body, or Maxis destroys the Earth for nothing. Even the Easter egg song, "Always Running" is far and away the saddest song.
    • Origins has the original four back, but not the crazy schizophrenic Richtofen, Comically Serious Takeo, crass drunk Nikolai, or Blood Knight Dempsey. Instead, we have a very solemn battle to save Samantha from Agartha.
    • If Shi No Numa was dark enough, Zetsubou No Shima in Black Ops III takes it to new levels. The map's atmosphere is dreary, the only sounds are crickets and what it seems to be screams or moans of pain, and everyone that managed to survive the zombies was killed by giant spiders, not to mention the dreadful experiments that took place in the island.
    • Gorod Krovi takes the four to a destroyed Stalingrad taken over by undead and dragons controlled by Group 935. All that can be seen in the distance is Russian aircraft desesperately trying to kill the dragons and artillery fire all around, alongside moans of pain all over.
  • Daylight Horror: Gorod Krovi, Buried and Shangri-la take place in broad daylight. Kino Der Toten might count, but the action is restricted to the interior of said cinema. Other maps take place either with a heavy fog or a grey sky (Die Rise, Tran Zit, Origins, Ascencion, Nuketown, Call Of The Dead) or during the night (the rest).
  • Deadly Doctor: Guess.
  • Did You Just Punch Out Cthulhu?: The main Easter egg of Revelations ends with the four killing the Shadow Man and banishing his masters back to their dimension with no hope of ever returning, although Maxis and Sophia sadly have to give their lives to help them achieve it however.
  • Deadpan Snarker: Richtofen in Black Ops III is a lot more sarcastic than his... older counterpart.
  • Death by Irony: Each of the original four's death in Black Ops III.
    • The Giant: Edward, who was central to the storyline, manipulated all the characters to further his plans and was the Big Bad of the main timeline, get uncermoniously headshotted by his Origins self as part of a plan he had no idea about in the intro of the map, meaning he is the only one to not have an Easter Egg about his death.
    • Der Eisendrache: Tank, the stereotipical angry gung-ho Marine, who was always ready to fight another day, is barely clinging to life in his stasis pod and die peacefully by his other self merely turning the life support systems off.
    • Zetsubou No Shima: Takeo, who always went about honor and serving the Emperor, got betrayed by the very same Emperor he was following with Undying Loyalty, was the subject of horrible experiments by Division 9 and dies by seppuku, the only way for a samurai to die with some honor.
    • Gorod Krovi: Nikolai, who always joked about killing his numerous wives in violent ways and was always drunk, goes ballistic when his Origins self mention the death of their first and only wife in an air raid, something that they couldn't prevent and wracked them with guilt, tries to kill his Origins self before getting a shotgun to the face.
  • Defcon Five: Played straight. Handwaved with DEFCON ONE locking down critical access to a few rooms, and FIVE releasing enough security to get you some new toys.
  • Deliberately Monochrome: Ascension begins this way. The color only returns when you turn on the power. Lampshaded at the start, right before Gersch requests your assistance.
    • Also, shown at the end of the Ascension side quest/easter egg where Samantha lets out a howl that disorients the players and brings back the monochrome coloring for a few seconds.
  • Depraved Homosexual: The fans suspect Richtofen 1.0 of being this.
  • Diesel Punk:
    • Very much so. Much of the Nazi tech in the game just echoes this.
    • Origins, the last map of Black Ops II, is built on this trope.
    • Shadows of Evil has an explicitly 1940's-style retrofuturistic setting.
  • Does This Remind You of Anything?: Crosses over with Double Entendre, many of the characters are prone to this.
    Nikolai "Taste my Russian steel!"
  • Double Entendre: Nikolai is full of these. Both good and terrible. For some reason they tend to involve Dempsey.
    (on Moon) "Such explosive power in my hands! No dirty thoughts, Dempsey."
    (getting a Shotgun) "Hey! Who wants to try out my new boom-dick!?"
    • And then we have this little gem from Call of the Dead's easter egg:
    Dempsey (to Richtofen after getting the last item): "Kinda sick of me to ask this, but Richtofen, is that a rod in your pocket?"
    • Later maps don't lack those even through the characters are supposed to be more serious.
    Dempsey: "Time to whip out my... little light!"
    Nikolai: "Who wants to play with my monkey? Anyone?"
  • Downer Ending/The Bad Guy Wins: At the end of Buried, which is the last map before Origins, players have the choice of either siding with Maxis or Richtofen. If Maxis wins, he banishes Richtofen from the Aether and uses his powers to open a rift to Agartha, which will destroy Earth in the process. If Richtofen wins, he destroys Maxis' soul, possesses one of the characters, gains full control over the Aether, and uses it to turn the Earth into his personal playground. Thankfully, this chain of events is undone when their Origins counterparts change this timeline by killing the original Richtofen.
  • Drop the Hammer:
  • Drowning My Sorrows: Nikolai would love to be doing this. He can't.
    • What he can't drown, he shoots. Like his first wife. She was bitch.
    • And there's no bloody Vodka in these Perk-A-Cola dispensers.
    • After Call of the Dead, Nikolai finally gets his vodka and makes references to being able to drink from it.
    • Gets a much sadder tone once you complete the Easter Egg in Gorod Krovi. The reason he drowns his sorrows is because his only wife was killed by artillery fire.
  • Eagleland: Tank Dempsey, a cross between type one and two, being an ultra-violent, ultra-patriotic psycho, who nonetheless sticks up for his un-American comrades.
  • Early Installment Weirdness: It can always be weird for players to return to the oldest maps of the series from the newer maps, which are much bigger in scope, for starters.
    • The first map, which was originally just a bonus easter egg anyway, lacked any perks or Pack-A-Punch. The Black Ops edition of it does get the Mule Kick put into it. Furthermore, the playable characters of it and Verruckt are nameless soldiers without any personality. Richtofen and the crew weren't introduced until Shi No Numa.
    • Pack-A-Punch wasn't even introduced until Der Riese, the final map of World at War.
    • The maps of World at War and Black Ops can feel incredibly barren and simple compared to the much more story-driven Black Ops II and III. It wasn't until Ascension that the main plot began to really take shape, and it wasn't until Black Ops II that the plot began to take center stage in the games.
    • Black Ops II and III also feature far more gameplay elements such as the Buildables, bows, and staves, whereas World at War and Black Ops were pretty straightforward with their guns and Wunder Weapons.
  • Earworm: The Pack-A-Punch jingle:
    "Friends, neighbors, ladies, gentlemen, if you're feelin' underpowered, I'll help you make amends.
    Just stick your weapon in the slot, and let it change your luck.
    Few things in life are guaranteed, but I promise this won't suck
    Punch your fists into the air and raise a rebel yell!
    There's lots of bad 'uns out there you need to send to hell!
    With Pack-A-Punch, I have a hunch, all your problems will be gone, but if you end up on the ground, sing a country western song.
    Pack-A-Punch (Everybody)! Pack-A-Punch (Yee-haa)! Pack-A-Punch! Pack-A-Punch! Pack-A-Punch (Everybody)! Pack-A-Punch! Pack-A-Punch(YEE-HAA!!!)Pack-A-Punch (WAA-HHAAAW)!"
    • Most of the Perk-A-Cola machines account for this, too.
  • Earth-Shattering Kaboom: Two. One in Moon where you blow up the Earth and another in Der Eisendrache, where you return the favor. Though technically that last one counts as an example of Detonation Moon.
  • Easter Egg: There are three types of Easter Eggs - Radios that serve as the backstory of Group 935, Dr. Maxis, or other important characters; ones that activate original music created exclusively for the map; or major Easter Eggs that directly affect gameplay and the storyline.
    • Black Ops II splits the story Easter Egg into two, as during the maps you can choose to complete an Easter Egg for either Richtofen or Maxis. The culmination of the main Black Ops II storyline has two different endings: Richtofen's side, where Richtofen causes Dr. Maxis to simply cease to exist, and then joins a character in their body, or Dr. Maxis' side, where Maxis throws Richtofen out of his spot as the "Demonic Announcer" and then starts to destroy the Earth to get his daughter Samantha back.
  • Earn Your Happy Ending: After eight years of maps and a battle across time and space, Richtofen, Dempsey, Nikolai, and Takeo are save the universe from the Apothicons and kill the Shadow Man. Despite initially wishing to destroy them, Monty agrees to send them back in time to become Primis, four revered warriors who led the first battle between humanity and the Apothicons. The crew lives out the rest of their days as heroes, saving the Earth from the Apothicons again, and ultimately, completing the cycle so that one day, they will save the universe in Revelations again. The cycle is complete, with the heroes achieving their destiny and true place in the universe.
  • Easy-Mode Mockery: In easy mode of Black Ops II, all Easter Eggs are disabled, save for the musical ones. These things can only be done on Original difficulty.
  • Elaborate Underground Base: Der Riese, though parts of it are on the surface.
  • Eldritch Abomination: The Apothicons. They are the true main antagonists of the series, bringing destruction and chaos to all dimensions, and are utterly alien in appearance and power. The Keepers as well, althrough they happen to be creatures hellbent in keeping the balance of the dimensions and aiding in the purge of the Apothicons.
  • Enemy Mine: One bloodthirsty American Marine and one always drunk Red Army soldier fight zombies alongside a mad Waffen-SS doctor and one fanatical Imperial Japanese officer. Cool.
    • In the trailers Dempsey and Takeo team up, despite them being direct enemies. Same goes for Richtofen and Nikolai.
  • Endless Game: If this mode DOES have an ending, it's most likely not what you would expect.
    • Which turns into Canon Discontinuity which each new map. Just when you think they're all dead, the teleporter overuse takes them to a new place. Except, maybe, for Five.
      • And then in Call Of The Dead the original cast shows up trapped, and you can help free them.
      • Subverted in Mob of the Dead, if you carry out the Easter Egg to completion.
      • And again in Origins.
  • Exactly What It Says on the Tin: Well, except for Shi no Numa and Five, which are Japanese zombies and zombified White House/CIA/American zombies. It's now simply Zombies Mode in Black Ops, subsequent games, and the iOS ports, due to the fact you don't fight just Nazis anymore.
  • Everything's Worse With Space Monkeys: In Ascension, you are attacked by cosmonaut undead monkeys.
  • Even Evil Has Standards: Applied to Nikolai and Richtofen, in that their respective factions are scared shitless of them. Especially Nikolai, who scared Stalin.
  • Evil Laugh:
    • Dempsey does this occasionally, but Richtofen indulges in this very often.
    • Expect to hear the announcer do this a lot when the Mystery Box is moved.
      Dempsey: 'Oh just when I thought we were getting along, box!'
  • Evil Sounds Deep: Averted with Dr. Richtofen, who has a high-pitched voice in spite of being a Nazi Mad Scientist.
  • Evil vs. Evil:
    • Mob of the Dead, where four, blatantly obvious criminals fight against hoards of the undead, led by an evil guard in Alcatraz. Yes, that Alcatraz.
    • Maxis vs. Richtofen, where the former wants to destroy the Earth, and free Samantha, and the latter wants to heal the Earth, and make it his own plaything, making the lives of whoever is still alive, complete hell. Either way, the result is crappy.
  • Face Death with Dignity: WW2!Takeo at the end of Zetsubou No Shima 's Easter Egg accept his fate and commit seppuku, with Takeo being the one actually killing him, contrasting with WW2 Dempsey who die while in stasis in Der Eisendrache and WW2 Richtofen who is summarily executed in The Giant 's intro.
  • Face–Heel Turn:
    • Richtofen in Moon, not that he was good to begin with, what with attempting to kill his partner, Dr. Maxis, and his daughter, Samantha Maxis, before the events in Der Riese, and brainwashing the other characters and using them as experiments, among other things.
    • Dr. Maxis pulls one in the Buried easter egg, by becoming the announcer and planning to destroy the world.
  • Feed It a Bomb: The Margwa in Shadows of Evil is only vulnerable when it has a mouth open, at which point you need to feed it bullets until the head explodes. Do this three times and it will die.
  • Feel No Pain: Zombies, being zombies, do not react in pain to the weaponry that hit or dismember them - they keep coming unless they die. They'll even generally crawl after you if you've knocked their legs off.
  • Foe-Tossing Charge: The Gauntlet of Siegfried in Gorod Krovi can allow you to pull one of these, crossing over into Megaton Punch territory as you hit your targets with enough force to both reduce them to Ludicrous Gibs as well as send them flying.
  • Film Noir: "Shadows of Evil", is explicitly going for this. Its characters are all Film Noir archetypes like "the Femme Fatale", "the Cop", "the Magician", and "the Boxer".
  • Fire-Forged Friends: Well, not friends, but as they are under increasingly serious attack, the characters will act more like a team. (At least they say they will. Whether they do or not is up to the players.)
  • Flaming Sword: The Keeper Sword in Shadows of Evil is wreathed in flame, similar to the Keepers.
  • Foreshadowing: Everywhere. For some notable examples:
    • The fly trap easter egg in Der Riese feels like a horror movie where you communicate with an unseen demonic force. Come Moon, it's revealed that's exactly what you're doing: whoever's soul is within an alien device is taken to another dimension, the Aether, where they can control the Zombies. Richtofen knew this all along and only in Der Riese did he realize it was all just a game to Samantha.
    • On the Wii version of Kino, one can find a very poor quality video clip revolving around the Great Leap Forwardnote . In Black Ops II, the first DLC map is in a location called "Great Leap Forward" in Shanghai, China.
    • Takeo muses in Ascension that the zombies are the greater threat than Richtofen and resolves to focus on the former. In a way, he's right: whatever force controls the Zombies and is the source of power behind whoever is the Demonic Announcer is a far greater threat than Samantha, Richtofen or Maxis. This evil entity turns out to be the Shadow Man and the Apothicons.
    • In Nacht, Der Riese, Ascension, and Shangri La, the Moon is clearly visible. You can just see a red smudge that grows more and more visible with each map. The final map of Black Ops and the Wham Episode of the story takes place on the Moon.
    • In Shangdi La, Takeo and Dempsey both realize Richtofen is up to something big. Turns out in Moon, everything so far has been a part of his grand scheme to take over the Zombies.
    • Some of the survivors of Black Ops II seem to realize Maxis intends to destroy the Earth, although considering all the insanity and hysteria of the apocalypse, the player probably didn't take them too seriously. They should have.
    • The translated cypher on the lyric video for "Where Are We Going" - "Let go and the beginning will become the end." - revealed what the final map would be like - a return to the original six major characters during the first zombie outbreak, which (for now at least) seems to wrap up the story and has the characters finally reaching the fabled [[spoiler:Agartha.
    • In the trailer of Der Eisendrache, Dempsey calls the titular map "a suicide mission". He ends up being the one to kill his WW2 self at the end of the Easter Egg.
    • All over the place in recent maps, where ciphers delivering clues about next maps are hidden.
    • The voices Richtofen and other characters have been feeling since the beginning of the series? Revelations strongly implies this to be the voice of the Shadow Man, who's bent on letting his masters, the Apothicons, destroy this dimension.
    • Notice how the plot of the series really started when a meteor of Element 115 landed in the swamps of Shi No Numa? That's because Element 115 is a material created by the Apothicons, who speak to whoever comes in contact with it via the Shadow Man and direct the listener towards bringing about the destruction of their dimension for them. Richtofen and Maxis eventually destroyed the Earth in the original timeline after the insanity of exposure to Element 115.
    • In Mob of the Dead, Weasel complains that he can't get the name "Nikolai" out of his head for some reason. Later, the opening cinematic of The Giant uses the Mob of the Dead round music when 2.0 Richtofen emerges from the teleporter. Later, the same cue is used during the first trailer for Revelations. In the end cutscene, after the Apothicons are defeated, Richtofen reveals that he took vials of blood from the Mob gangsters, as their dimension had been sealed off from the Apothicons, creating a paradox that allowed the crew to survive the resetting of the universe.
    • In Origins, we see strange statues in the likeness of the crew in the Crazy Place. Ultimately, the Origins crew is allowed to live out the rest of their days as the heroes and leaders of the human-Keeper alliance to fend off the Apothicon invasion in Primis, making it clear why there were statues of the crew in the Agarthan place.
  • Forgot to Pay the Bill: Nikolai sometimes says this in Kino der Toten.
    "Who didn't pay electric bill?"
  • Four Is Death: Takeo when finding a nesting doll on Ascension:
    "One becomes two becomes three becomes... Death?"
  • Frickin' Laser Beams:
    • If a gun fired bullets before you upgraded it in the Pack-a-Punch, chances are, it'll now fire lasers.
    • The Ray Gun technically counts, but it's more like O-shaped beams of death.
    • The Mark II variant plays straight as, well, a laser.
  • Gambit Roulette:
    • Richtofen used the group to help him find Samantha so he could switch bodies with her and gain control of the zombies.
    • Dr. Maxis had a counter plan. Now existing as a digital entity, he had recordings instructing the party how to weaken Rictofen. That was the destruction of the Earth's atmosphere, essentially loosening Rictofen's control over the zombies on Earth.
  • Gatling Good: On the map Five, you can find a power-up which gives you the Death Machine, a portable minigun with unlimited ammo, for a limited time.
    • The Death Machine serves as a power-up for the rest of the Black Ops maps. As of Der Eisendrache in Black Ops III, it is also avaliable in all Black Ops III maps and can also be summoned with a specific Gobblegum.
  • Giant Mook: Most of the "Boss Zombies" fall into this category, including George A. Romero, Brutus (aka the Warden), the Panzer Soldat, the Margwa, the Trasher and the Russian Mangler.
  • Ghost Town: Considering that Buried is set in an underground, mostly-abandoned ghost town, and you'll wonder why they built it there in the first place.
  • Greater-Scope Villain: Throughout the series it's been hinted that there's a larger evil force behind the zombie mayhem, greater than Richtofen or the Maxis family. The final Revelations DLC map from Black Ops III confirms that the Shadow Man and the other Apothicons were behind it all from the beginning.
  • Groin Attack: This happens to Nikolai.
    "Oh No! It's biting area is closer to my fun fun area!"
  • Griefer: Actually encouraged in a game mode called Grief, where two teams must compete to win, despite being technically co-operative. You have actively sabotage the other team to survive, as you can't directly attack the opponents.
    • 1. Using an EMP Grenade while you're using the Mystery Box. It cancels the spin and you don't get your points back!
    • 2. Using said EMP, however now on the Pack-A-Punch not only powers it off, but will get rid of whatever gun was in it. Massive trolling.
    • 3. Blocking you from using the Bus by blocking the doors. Good luck running through the fog with no idea where to go with those bloody denizins coming after you...
  • "Groundhog Day" Loop: Important to the Mob of the Dead map's storyline. The four mobsters intended to escape Alcatraz using a plane constructed by Weasel, but infighting caused Sal, Billy and Finn to turn on the former and kill him on the prison roof; a crime for which they would be exectued via electric chair. They ended up in the Afterlife, where they attempt to recreate their escape while fighting zombies. Save for Weasel, the mobsters cannot recall what exactly happened, but regain their memories (if the map's Easter Egg is performed), in which case, they kill Weasel and die once more, repeating the cycle. The cycle can be broken if Weasel successfully defeats the others, at which point he is freed from his repeated deaths.
  • Guns Akimbo: When you upgrade your pistol, you'll gain two of them. They both spit out grenades. Nixon also wields two shotguns in the intro to the first Black Ops Zombies map.
    • Again in Moon, where the Wonder Weapon Wave Gun can be taken apart on a whim to become a dual wield shock gun.
    Ritchofen: "Double the pleasure, double the pain, double the DAMAGE!"
    • In Zetsubou No Shima, the Marshall 16 Dual Wield is avaliable from the mistery Box.
    • In Gorod Krovi, the GKZ-45 Mk. III are basically two experimental weapons: one that fires clouds that slow down zombies, similar to the Paralyzer, and a Ray Gun Mark III in the other hand. Firing the Ray Gun into the cloud of the GKZ turns the cloud into a Gersch Device-like black hole. The NX Shadowclaw semi-automatic crossbow is also avaliable in Dual Wield version.
  • Ghostapo: This is what happens when you expose alien metals to undead Axis soldiers.
  • Healing Shiv:
    • A literal example in the form of the Pack-A-Punched Ballistic Knife, the Krauss Refibrillator. You can revive downed players by stabbing or shooting the blade at them.
    • In Gorod Krovi, the NX Shadowclaw Dual Wield crossbow does this once upgraded.
  • The Heavy: Richtofen is the most prominent antagonist for Black Ops and Black Ops II. However, in Black Ops III, the Shadow Man takes this position as he's the most prominent antagonist representing the true antagonists of the franchise, the Apothicons.
  • Hellhole Prison: Mob of the Dead's Alcatraz is portrayed as this, showing massive amounts of decay, shoddy repair, and overrun with zombies covered in razor wire, and impaled with chunks of wood. Though considering that this is while the group is in purgatory, it's understandable.
  • Heroic Mime: The soldiers in Nacht der Untoten. Thankfully, the other levels avert this completely.
  • Herr Doktor: Richtofen.
  • Honor Before Reason: Takeo Masaki. To the point he has a proverb related to honor tattooed on the insides of his eyelids.
    Takeo: Argh! Your foul odor dishonors my sinuses.
  • Incredibly Lame Pun:
    • Nikolai is fond of these.
      Nikolai: And the limbs go flying! How's that for an ARM-y?! Get it? With the arms?...(no one answers) ...fuck you.
    • Rictofen also does this... In a more funny, sinister way.
      Richtofen: He can't fight now... He's being... DISARMED! Ahahahaha!
    • Lots of them in newer maps.
      Dempsey, upon seeing a Trasher: "He's like a boar! A... vegetaboar!"
      Dempsey, when turning on the Giant Eye Laser: "He's got his eye on you, maggot addicts!"
      Ritchtofen after turning on the Electric Trap: The extreme voltage I conduct will amplify my resistance to the current hellspawn circuit, ehehe... That's enough electricity puns, moving on.
      Nikolai: It crawls like baby... Hellpiglet! Hehe, see what I did there?
  • Infinity +1 Sword: All the way back to the very first map, Nacht der Untoten, the Random Weapon Box would occasionally give you a Ray Gun, which could usually kill zombies in 1 hit, even on higher rounds. Shi No Numa gave us the Wunderwaffe which took out multiple zombies with one shot. The last World At War map, Der Riese, gave us the Pack-A-Punch machine, which upgraded your weapons into super-enhanced death machines. Even the weakest weapon, the M1911, turned into an automatic grenade launcher when put into the machine.
    • Slowly gets subverted the higher the round number due to the zombies getting more health every round. The subversion is why the Bowie Knife was introduced in Der Riese, and THAT gets subverted after a while.
    • And then the Thundergun in Kino der Toten, which is always a one hit kill. And then the Winter's Howl on Five, and they get subverted eventually, too! But that's only due to ammunition reasons.
    • Then there's the Wave Gun in Moon, which follows the Thundergun in being a one hit kill. But not only that, but it can be taken apart to make a dual wield version that is also a one hit kill!
    • The pistol inside the bus in Tranzit, usually one hit kills zombies with its three round bursts, costs less than most other weapons, and is available right from the start.
    • Probably the king of all these weapons is the Sliquifier from Die Rise. Originally thought by the fans as an absolutely terrible new Wonder Weapon, the Sliquifier has proven that it is the greatest Wonder Weapon yet. There's a video in which a player kills 91 zombies in a single shot.
    • In Tranzit, the superweapon was a Jet Gun that worked on a cooldown and shredded zombies to bits. It wasn't that great. With the release of Buried, we receive the Paralyzer. Insanely quick cooldown, slows zombies to a halt and kills them in seconds, massive range, and you can fly in the air with it? Sign me up!
    • In Shadows of Evil, you make some sort of Eldritch Abomination gun that shoots black holes. It's like having ten Gersch Devices!
    • In Der Eisendrache, it is possible to obtain a bow by feeding three dragons. The bows can be upgraded to bows that draw in power from elements: the Storm Bow, the Void Bow, the Wolf Bow and the Lava bow.
    • In Zetsubou No Shima, the KT-4 and it shoots a liquid that makes spores grow in zombies and makes them explode, similar to the Sliquifier.
  • Innocuously Important Episode: Mob of the Dead is a self-contained story depicting four mobsters trying to escape from an overrun Alcatraz, dealing with their own demons and whether or not they deserve redemption for their crimes. Only in Black Ops III does it become apparent that this standalone map is actually perhaps the key to everything. The map revolves around breaking the "cycle" of the mobsters' tenure in Purgatory. Furthermore, the pocket dimension of Mob of the Dead has been sealed off from the influence of the Apothicons, the main antagonists of the series. The Origins crew ventures here to take blood samples from the mobsters, which creates a paradox that saves them from Dr. Monty's reset button upon the final defeat of the Apothicons. This visit to Alcatraz not only saves the heroes lives, but saves the entire universe, as Monty is convinced to send the crew back in time to the first battle with the Apothicons on ancient Earth, which will one day lead to Monty seeking out the same four men again in the present. The Origins crew takes their true place in the entire universe, and complete the cycle, allowing Monty and the rest of reality to move forward from the evil of the Apothicons.
  • Insane Troll Logic: Maxis's plan to save the world from zombies: blow it up, at least at first glance. He was actually out to destroy the Earth's atmosphere and strike a critical blow to Richtofen's power over the Aether.
  • Interactive Narrator: All the player characters can hear the Demonic Announcer. Leading to these lovely exchanges:
    Demonic Announcer: FETCH ME THEIR SOULS!
    Nikolai: "Oh, no! They're going to fetch our souls again!"
    Dempsey: Fetch my grenade, Devil-voice!
  • Jungle Japes: Shangri-La and Zetsubou No Shima.
  • Kill It with Fire: Flamethrower + Nazi Zombies = Good times, but Flamethrowers are useless unless someone's got the Insta-Kill power-up.
    • Flamethrowers are useful if you have the Double Tap perk, because the increased fire rate means that the zombies burn up a lot quicker. Pack-A-Punching it adds nitrogen cooling to your flamethrower, making this much more practical.
    • Black Ops III allows a second pack-a-punch for all bullet-firing guns, and one of the secondary bullet types is Blast Furnace. Once triggered, it sets all zombies in the vicinity on fire.
  • Knife Nut:
    • Everyone in Der Riese once they get their hands on a Bowie Knife, which looks more like a short sword.
    • Misty from Tranzit is a self admitted knife nut, and was a six-time knife fighting champion.
    • The Origins characters in the newer maps once they buy a Bowie Knife.
      Demspey: Welcome to the one-stop maggot spillin' brain muncher chop shop. Proprietor: Tank Dempsey!
  • Lampshade Hanging:
    • Some of the characters will comment on the finding of the musical Easter Eggs being just that. They'll also get pissed off every time the Mystery Box chucks up a Teddy Bear instead of a weapon.
    • After an explosive caused by Nikolai leaves a zombie alive, but legless, he will make a remark on how players do this to be free to run around the map and do whatever:
      Look, I just made a new pet. I'll take it for a walk for about five minutes while the rest of you dick around.
      Dempsey, when out of ammo: Hey, player! Drop the chips and get me some ammo!
      • It gets more and more explicit as the DLC maps come in, with the last one hanging these after almost every power-up pickup.
    Dempsey, after picking up a nuke: "Gotta love how that doesn't hurt us. Wait, is my hair falling out?!"
    • The Call of Duty games brought in "quick scoping", that is, use a sniper rifle scope for a millisecond for a kill. Get one to Sarah in Call of the Dead and she will bring this up.
  • Large Ham: Pretty much everyone after a kill.
    Dempsey: I'm gonna do a jig on your insides, maggotsack!
    Nikolai: "No, it's my Vodka! MINE! MY OWN!"
    Richtofen: "The Doctor prescribes you... PAIN!"
    Takeo: "Your blood will rain on me!"
    Kennedy: "Forgive your enemies, but NEVER, EVER, forget their names!"
    McNamara: "Consider yourself, ITEMIZED!"
    Castro: "Only I can punish crimes of such MAGNITUDE!"
    Nixon: "Get your hands off me, HIPPIE!"
    Misty: "Oh ho, you're done, BITCH!"
    Richoften: "I DRINK YOUR PAIN!" *slurping sounds*
    Dempsey: "I WILL CUT YOU BAD! REAL BAD!"
    Ritchtofen, when knifing a zombie: "SILENCE!!!"
    Takeo: "You? Kill me? NOO! I KILL YOU!"
  • Lethal Joke Weapon: The Golden Spork in Mob of the Dead. As ridiculous as this sounds, it's more lethal than the Galvaknuckles. Yes, a spork is more deadly than electric brass knuckles! Holy crap! To specify, the Golden Spork is five times more deadly than the Galvaknuckles. Getting it requires using the acid infused Blundergat in the laundry room after mixing the spoon in the bathtub of blood. A laugh later, and go back to bathtub. Have fun using it to Curbstomp zombies.
  • MacGuffin: Each maps has one or several of those, necessaries to complete it's Easter Egg. The Summoning Key can be considered as one of to the entire Black Ops III storyline.
  • Mad Scientist: Richtofen.
  • Magic Music: In Origins, gramophones and records can apparently open up entire tombs, and open portals to another dimension.
  • Magikarp Power: That Pack-A-Punch machine can turn your somewhat useless weapon, into a slaughtering machine, save for a few exceptions.
  • Meaningful Name:
    • "verrückt" means "crazy" in German.
    • Nacht der Untoten, which means Night of the Undead in German, and Shi no Numa, which is Japanese for Zombie Swamp or Marsh of Death... and you fight Japanese Zombies in it.
    • Kino der Toten in Black Ops roughly translates to Theater of the Dead, which is appropriate considering it's a Shout-Out to Inglourious Basterds.
    • Ascension is a Soviet rocket launch facility, complete with cosmonaut training device and zombie astro-monkeys.
    • Call of the Dead, combining Call of Duty and Night of the Living Dead (1968) (the latter of which was directed by George A. Romero, who shows up as the final boss of the level).
    • Mob of the Dead has 'Icarus'. A plane that is supposed to fly the Mobsters out of Alcatraz, crashes on the Golden Gate Bridge.
    • Buried is named for the character's situation - they have to decide to follow either Richtofen or Maxis, but they overall don't have the best of hopes anyway. No matter who they help, they all die in the underground town, unable to return to the surface.
    • Der Eisendrache is German for "The Iron Dragon", named after the dragons you have to feed, and that it is the motif of the long gone king.
    • Zetsubou No Shima translates from Japanese to "Island of Despair". Considering what happens in the island...
    • Gorod Krovi translates directly from Russian to "City of Blood."
  • Mood Whiplash: A lot of the musical easter eggs by Elena Siegman. Often, they change from normal singing to furious screaming in the blink of an eye. For example, in "Beauty of Annihilation":
    Bring me down... WITH 7.62 AND HIGH VELOCITY!!!
    Bring you down... WITH 7.92 AND NO IMPUNITYYYYY!
    • The songs themselves can do this; having a playlist of all the songs on random and you can go from a quiet solemn song (Always Running) to a screamo (Paredolia + Coming Home) and back to a 'soft' grunge song (Lullaby for a Dead Man) within a ten minute span.
  • More Dakka:
    • Pack-a-Punching your guns in Der Riese onwards often includes a gigantic increase in firing rate. It even turns some semi-auto weapons into full-auto weapons. However, trying to compensate for a lack of accuracy in this manner will just cause your ammunition reserves to run dry. (although the lack of accuracy becomes a problem because headshots in the later rounds are the only way to quickly kill a zombie.)
  • Ms. Fanservice:
    • Sarah Michelle Gellar is wearing tight leather pants and a crop top that bares her midriff, which was originally her costume for the movie she was filming with Romero and the others.
    • Misty wears a plaid shirt tied into a note leaving most of her belly exposed, and wears short-shorts as well.
    • Jessica in Shadows of Evil was purposely trying to emulate this since she was performing in a burlesque show before she was abducted and cast into the apocalypse of Morg City.
  • Multiple Head Case: The Margwa in Shadows of Evil has three heads. All three have to be destroyed to kill it.
  • The Multiverse: The Black Ops III zombies arc is the original crew's attempts to erase the zombies from all realities, and save it all from the Apothicons, ancient evils that seek to destroy all realities.
  • Mythology Gag:
    • In Origins, the steps to the Easter egg are the steps of Reznov's plan during the Black Ops campaign.
    • "Gag" might not be the right word, considering the mood of the scene, but WW2!Takeo's fate is eerily similar to Reznov's.
    • In Revelations, the license plate of the truck in the spawn area reads "M 45 ON", which is L33t L1ng0 for "Mason", the protagonist of the first Black Ops.
  • Multiple Endings: Keeping with this trope being used for the campaign, the storyline of the Black Ops II season employs this. Both Richtofen and Maxis are asking the main characters to aid in their quest to take firm control of the world or heal it, respectively. The canon ending is the Maxis ending, in which he reveals he was Evil All Along and used you to attain ultimate power to destroy the Earth. The (now confirmed as of 2017) non-canon ending is the Richtofen ending, where Richtofen assumes ultimate power over the Aether, kills Maxis, and Earth is now his personal plaything. Samuel also becomes the unwilling mortal host for Richtofen's soul whenever he likes.
  • Names to Run Away from Really Fast: All the upgraded weapons sound scary. Well, except for the PTRS-41, which is called The Penetrator.
    • The Dingo becomes the Dire Wolf once pack-a-punched.
    • The SVG-100 turns into the Ikken Hissatsu. Which is Japanese for "To annihilate in one blow".
  • Nazi Nobleman: Averted in Richtofen's biography, which makes reference to this trope, saying he gained influence amongst German's high-class, but disagreed with the Nazi Party (though mostly because he considered them not evil enough). He did join the army to fulfill his sadism, however. And also Averted with Group 935 as a whole, as Maxis joined with the Nazi party to further their agenda, but Maxis is strongly implied to have stalled as much as possible so as to not hand their advanced weaponry over to the Third Reich.
  • Nice Job Breaking It, Hero!:
    • The Call of the Dead cast, unbeknownst to them. They gave the Vrill Device to Richtofen, who would use it to take control of the zombies in the Aether, and this would lead to the Earth's destruction.
    • No matter who the Green Run group help, they only make things worse. If Richtofen succeeds, the Earth remains as is, and Richtofen ends up trapped in Samuel's body and seems doomed to die with the other three. If Maxis succeeds, he destroys the Earth and everyone still on it. The worst part? He still fails to find Agartha..
    • Richtofen and the crew all manage to save their 1.0 versions and create the perfect world... Then Maxis fiddles with the Summoning Key and gets tricked by the Shadow Man. Who then proceeds to unleash his overlords on the perfect world that Richtofen worked so hard for. Dr. Monty admits it's not really Maxis' fault, as he doesn't actually have a soul since he only had his brain to work with.
  • Nazi Zombies: Trope Namer. It was originally titled "Nazi Zombies", and involved the players surviving hordes of Nazi zombies; but the Nazis stopped appearing starting in Call of Duty: Black Ops, and the game mode was renamed "Zombie Mode".
  • Ninja Pirate Zombie Robot:
    • Japanese Zombies!
    • Flaming exploding zombie dogs!
    • Russian Cosmonaut Zombies!
    • Mutant Jumping Space Monkeys!!
    • Now completely and utterly crushed by not one, not two, but THREE 1000ft tall giant robots in Origins!
    • Now summoned by the spawn of the Apothicons, complete with turning into tentacle monsters and making living guns that shoot black holes!
    • And now including zombies and tidbits from ALL maps in one single place alongside Eldritch Abominations you couldn't imagine in your worst nightmares!
  • Nintendo Hard: The game is a lot harder to play solo, especially if you aren't intimately familiar with the maps and zombie behavior. There's a huge emphasis on headshots and all the players are Two-Hitpoint Wonders. Black Ops takes things a step further by making it much harder to hold up in one spot, introducing ankle-biting gas zombies, and nerfing the machine guns. If you know how to properly lead the zombies, though, it's a lot easier to get high scores playing alone than it is with groups. In later games, there is a way to lower the difficulty, at the cost of being able to do the Easter egg.
  • Not the Fall That Kills You:
    • Done in Mob of the Dead, where the mobsters end up crashing into the Golden Gate Bridge support beam with their makeshift airplane and fall to the ground below, they just merely get dazed as a result. Justified, they are not in the real world, they are in purgatory.
    • A little purge from the giant robot and the player falls a great height in Origins, 1000 ft. They survive of course. Handwaved somewhat with this quote.
    Richtofen: The initial test subjects did not survive the purge sequence, hence the addition of the velocity compensator.
  • Powered Armor: What the Panzer Soldat technically wears.
  • Ooh, Me Accent's Slipping: Nikolai in Der Riese, albeit for one line:
    Nikolai: His head is waist high, Dempsey, (suddenly losing Russian accent) don't get too excited!
  • Our Zombies Are Different: They're made via "Element 115" or repeated teleportation, and don't need headshots. Their eyes glow and move faster over time, and they're somewhat controllable.
    • In fact, later zombies can survive for short times without their heads. At a late enough round, you could have an armless, legless, headless zombie still making its way towards you.
    • With the right application of 115, they can be turned back into regular humans. This includes George Romero, but only for a short time.
  • Pet the Dog: Richtofen is noticeably empathetic towards the Hellhounds when they come knocking at the door. Considering Nazi Germany had a surprisingly humane policy on animals... That, and the fact that he helped create the first Hellhound, which he used to kill Maxis and Samantha by locking them into the room it had appeared in. At least, that's what everyone, including Rictofen thought. Turns out, they were teleported to the Group 935 base on the Moon.
  • The Power of Rock: Well, technically, Rock was far from invented yet in 1918, but a Gramophone and some records are needed in Origins to open up specific areas, all which are very important to creating the map's wonder weapons.
  • Precision F-Strike: The end of "Archangel".
    I am the end
    a fucking archangel
  • Pyrrhic Victory: Both sides in the original timeline have variations. If you follow Maxis, Richtofen's threat is no more, but Maxis is arguably worse, with him destroying Earth outright. If you follow Richtofen, he will be excited, but he will soon realize how dangerous the battlefield is again, how he gets bored, and how there is a stench.
  • Poison Mushroom: The Tombstone perk cola in Black Ops II, which gives you a quick suicide if downed.
  • Porky Pig Pronunciation
    Dempsey: "Gotta link up this terra... er, tele... bah... machine."
  • Power-Up:
  • Power Up Letdown:
    • The Death Machine in some Black Ops maps can be this on later rounds when you realize that it doesn't do that much damage and makes you unable to run. And then you realize you can't buy things or revive people when you have it...
      • Averted with the Black Ops 3 version of the Death Machine, which tears through crowds regardless of round.
    • The Nuke powerup instantly kills every zombie on the field and awards all players 400 points each. The problem with this is that the number killed are usually worth more than the points the powerup gives you, it makes attempts to activate secrets on the map harder by possibly ending the round (leaving one or two zombies alive is often used to extend a round indefinitely for this purpose) or killing zombies that players need to directly kill for certain reasons, and in the early rounds you can grab it by accident simply because it's cheaper and earns more points to knife zombies than shoot them.
  • Psycho Electro: Dempsey's more... fond of the Wunderwaffe than the other characters, as well as the Storm Bow in Der Eisendrache.
  • Rasputinian Death: Nikolai notes the ability for a zombie to keep coming at you with arms, legs, and even a head blown off in one of his quotes.
    Nikolai: "What are you? Fucking RASPUTIN?! Just die already!"
  • Recycled IN SPACE!: The Rezurrection map pack features a new map on the moon.
    • Also in that map is an achievement called 'Perks in Spaaaaace', which is unlocked once you've had all 8 perks at some point in the game (not necessarily all at the same time)
  • The Reveal:
    • Moon reveals that Richtofen has been using the other three to help him enter the Aether and take control of the zombies.
    • Buried reveals that Maxis has been plotting to use the survivors of Earth to help him take Richtofen's place in the Aether, only to destroy the Earth so he may reach Agartha and find Samantha.
    • The Giant sets forth the new direction for the story, and that the Origins crew is from an alternate dimension from the one up to Buried. They are also systematically killing their original timeline selves to prevent the original timeline from happening.
    • Gorod Krovi reveals that Dr. Monty is an omnipotent being who has tried to keep the universe in balance, and is going to help the gang save it.
    • Revelations has already set forth a ton of reveals just in the pre-release material, unsurprising given the title of the map. The ending of Origins was actually set in a reality inside the Aether, created by Dr. Monty as a safe haven for new incarnations of the original four and the Maxis' after all the horrors they've faced. Furthermore, the Apothicons are unveiled as the true main antagonists of the series, as they are beings of pure evil who seek to destroy the universe by sending Element 115 to all realities - and the element corrupts any who come into contact with it, and in the original timeline's case, led Richtofen and Maxis to destroy the Earth. The Shadow Man is properly identified as the chief enforcer of the Apothicons, who now are about to conquer the Aether and destroy the entire universe.
  • Revolvers Are Just Better: Played straight, and subverted. The revolver is a good weapon and a good choice for early rounds... but later on, its low rate of fire and the zombies' increased health is a crippling weakness.
    • Completely played straight in Transit onwards, where the revolver Executioner is massively more powerful than most of the weapons in the box, even the Ray Gun!
    • And in Buried, we get a new revolver by the name of the Remington New Model Army. It's damage against the body is above average, and it has a decent reload time. However, it gets massive damage multipliers with headshots. Said multipliers rise even higher when the weapon is upgraded.
  • Rule of Cool: Why are you fighting as a crazed Nazi, a drunken Russian, an honor-obsessed Japanese soldier, and an even crazier American? Why are there miniature grenade launchers and electric guns? Who cares?
    • Alternatively, why are you fighting zombies as John F. Kennedy, Richard Nixon, Robert McNamara and Fidel Castro in the Pentagon? I think you know exactly why.
      • Gets better when celebrities are thrown into the mix.
      • And why is Sarah Michelle wearing a sleeveless cut off shirt in the middle of Siberia?
      • And eventually, mobsters fighting zombies in Alcatraz.
    • The weapons themselves. Started from the Ray Gun and now we got cluster grenades disguised as a Russian nesting toy and a miniature black hole generating bomb along with elemental based weapons.
  • Running Gag: When attempting to purchase something he doesn't have enough points for, Nikolai will make references to a stripper who took his money:
    Nikolai on Kino der Toten: What?! That stripper must have stolen my money!
    Nikolai on Ascension: That stripper DID take all my money!...bitch....
    Nikolai on Shangri-La: Where does all my money go? Vodka, she is cruel mistress. (which, in itself, is a Running Gag)
  • Set Right What Once Went Wrong: Richtofen's goal in the Black Ops III storyline is stopping himself from accessing the MPD in all realities.
  • Scenery Gorn: Nuketown Zombies is pretty much Nuketown from the first Black Ops...given a very destructive makeover.
  • Screams Like Alittle Girl: Nikolai does this in Shangri-La.
    Aah! It almost made me woman!
    • Nikolai actually does this a lot, particularly when something comes close to hurting, um... his "Little Nikolai".
  • Semper Fi: Tank Dempsey. Oo-fuckin'-rah.
  • Sequel Difficulty Spike: Black Ops II 's zombie mode is a few orders of magnitude harder than the one in the original Black Ops, especially on Solo. Zombies get stronger and faster much earlier on, and the smaller levels and narrower corridors make it much more difficult to form zombie trains. Black Ops 's zombie mode was already more difficult than World at War 's, as each weapon had been nerfed, and machine guns were less viable.
    • Played straight with Black Ops III. The zombies run faster and are able to attack MUCH faster than in previous games - to the point that being trapped is basically a death sentence, and one running zombie is a HUGE threat. To not make it downright impossible, players can now take three hits without Juggernog. Not that it helps...
  • Sequel Escalation: Each of the DLCs' settings and atmospheres become progressively more over-the-top.
    • Black Ops' first Zombie Mode map features John F. Kennedy, Richard Nixon, Robert McNamara and Fidel Castro fighting zombies in the Pentagon during JFK's presidency days/weeks after the Cuban Crisis.
    • Ascension brings the group from a Nazi theater to a Russian rocket base.
    • And as for Call of the Dead, well........
    • And now the final Zombies map being produced for Black Ops has Tank, Nikolai, Takeo, and Richtofen fight zombies on a base on the surface of Earth's moon. If that isn't absurdly over the top then I don't know what is. About as over the top as the Earth blowing up.
    • Black Ops II has TranZit, one of the biggest Zombie Mode maps to date, featuring interconnected areas that also serve as smaller maps. The premise behind said map counts as it shows the very destructive aftermath of Richtofen's antics in Moon.
    • Now we have Die Rise, which is also an incredibly large map, and expands greatly on the after affects of Moon and the conflict between Doctor Maxis and Richtofen's plans.
    • And after that, "Mob of the Dead." This is the largest zombies map to date, with a boss who can shut down perks and the box.
    • The final map, "Origins:, takes place during World War I, in a Dieselpunk France, is the largest map to date, features a tank you can ride on, and a skyscraper-sized robot.
    • Black Ops III starts relatively tamely with ''Shadows of Evil, where you fight zombies in a 40s city. And then the aliens shows up. And then you fight a servant of the ancient evil the maps have been foreshadowing since the beginning.
      • The Giant: Did Richtofen just got killed by his Origins self, saying it's to "secure a better tomorrow"?!
      • Der Eisendrache: Well, there goes the Moon remake.
      • Zetsubou No Shima: Zombie-eating plants, player-eating zombie-plant hybrids, and gigantic spiders. Have fun sleeping!
      • Gorod Krovi: Dragons! Nazi flying drones! Ultra-advanced German AI! More giant robots! Giant Russian zombies with arm cannons!
      • Revelations: Now we combine all maps in one huge frankendrabble in a fight to save the ENTIRE universe and all of existence as it is known from an abominable, tentacle-wielding ancient evil.
  • Serial Escalation: This secret on Ascension. It requires a LOT of time and is extremely difficult to do on a regular room unless you know exactly what you're doing.
    • Every subsequent Zombies map has even more elaborate Easter Eggs, culminating in the destruction of the Earth.
      • As of Black Ops III, the Origins characters are in a mission to destroy all of their WW2 counterparts to avoid the collapse of dimensions, and creating a perfect world for them to live away from all the fighting.
  • Silliness Switch: The main campaign of World at War is serious. As you might have guessed, this isn't. Well, eventually.
    • And then it becomes progressively darker.
    • The trailers and teasers for Nazi Zombie maps and Dead Ops Arcade are pretty serious.
    • At the end of Black Ops after hearing a solemn quote from JFK, the game cuts away to JFK joking about said quote with Castro, Nixon, and McNamara just before the zombies attack.
    • Dead Ops Arcade takes the cake though. If the bleeptune music and the helicopter and tank power-ups weren't a big enough clue, maybe the spacesuit gorilla will tip you off.
    • With the Earth blowing up in ''Moon'', it's safe to say that the tables have turned.
    • Extremely averted in Die Rise, where the beginning of a new 115-related plague and the absolute rule of Richtofen are shown.
    • Averted again in Buried, if you listen to Maxis, he becomes the Demonic Announcer, and tells you that he plans on destroying the Earth to be with Samantha. Listen to Richtofen, and he jumps into Stuhlinger's body.
    • Black Ops III moves the story firmly into that of a Cosmic Horror Story, as it becomes a desperate battle against the Apothicons, who are trying to destroy the universe.
  • Shotguns Are Just Better:
    • The Executioner. A shotgun revolver that has a lot of spare ammo. Even better upgraded.
    • The KSG in Origins. It still fires slugs, which gives it massive range for the weapon, and when upgraded, you have more ammo than the rest of the shotguns. Add a reflex sight, fast mag, and massive stopping power (Even better with Double Tap II) and you've got the one weapon you can use for the rest of the game.
    • The 205 Brecci and the Haymaker 12 in Black Ops III. Pack-a-punched, both have around 120 plus shells available and utterly annihilate anything in it's way - to the point that most zombies simply become red mist. Hell, even the KRM-262 pump shotgun is amazing once it's pack-a-punched.
  • Shout-Out:
  • Slippy-Slidey Ice World: "Call of the Dead", taking place in an icebreaker stuck in, uhm, ice.
    "I really didn't dress for the cold."
  • Small Girl, Big Gun: Buffy addresses this upon picking up a Death Machine.
    Sarah: Huh, this gun's bigger than me.
  • Smurfette Principle: Lampshaded/invoked in Black Ops by Dempsey.
    "Maann, I wish we could trade Richoften for a hot chick. I'm getting lonely here..."
    • However, it's played straight in Call of The Dead, with Sarah Michelle Gellar being the only female.
      • And after completing Richtofen's Grand Scheme on Moon, Samantha Maxis becomes the the second female character playable in Zombies via a soul transfer with Richtofen.
      • Played straight again with Black Ops II's Zombies mode, wherein Misty is the sole female character.
      • Also played straight in Black Ops III's Zombies, where Jessica Rose is the token female.
  • Sociopathic Soldier: All of the speaking soldiers enjoy the slaughter far too much.
  • Soul Jar: The Summoning Key can be used as this, catching and preserving the soul of the recently deceased.
  • Soviet Super Science: In the first Black Ops DLC map, Ascension.
    • Also in Gorod Krovi, where it shows they became advanced enough to create mechs and arm cannon prosthesis in masse.
  • Smoking Is Cool: Fidel Castro. He lampshades it.
  • Standard FPS Guns: In addition to the standard Call of Duty weapons, the Wunderwaffe fills the role of the electricity gun.
  • The Starscream: Richtofen to Maxis during their time in Group 935. Maxis refuses to allow Richtofen's experiments with the teleporters to continue, convincing Richtofen to work behind his back. Eventually Richtofen decides Maxis is unfit to lead 935, especially after declining to mass-produce his prized invention, the Wunderwaffe. Maxis had his reasons, as he truly had no intentions of giving such powerful weapons to the Third Reich, who were funding them at the time. Things probably would not have gotten so bad if Maxis had bothered to explain this to Richtofen...
  • Time Travel: First seen when Element 115 overloaded the teleporter in Der Riese to send our heroes to the future.
    • The basis of the entire storyline. Includes Temporal Paradoxes, Alternate Timelines, and more.
    • And again in Call of the Dead, when they managed to reach modern times.
    • The time bomb does the exact opposite in Buried, it send players back in time, to the point when it was set down. If you lost your entire team, *click* they're back with all of their weapons back.
  • Third-Person Person: Nikolai seems fond of this.
    "Nikolai will put their brains on the outside!"
  • This Is for Emphasis, Bitch!: The upgraded M1911 pistol is called the C-3000 b1atch35.
  • Those Wacky Nazis: Richtofen is a mad doctor. His former buddy, Doctor Maxis, was much more level headed, though still a Nazi.
    • Actually, Group 935 is a worldwide group and preceded the Nazi party. They simply decided to help the Nazis by giving them some of their Wonderweapon technology in exchange for funding.
  • Unstable Equilibrium: If you can avoid getting knocked down, get headshots consistently, and Pack-A-Punch your weapons to stay in the game, you'll rack up a nice buffer of points and the zombies can be very easy to kill even in rounds 20-30. Conversely, getting downed forced you to rebuy perks while being chased by zombies, and dying in a round forces that plus the Pack-A-Punch, which will cost a lot of points that are harder to earn without those features. Combine that with the cost of reloads and the ever-increasing strengths of the zombies, and it can become borderline impossible to keep playing.
  • Unusual Euphemism: Nikolai uses a couple of these in Shangri-La.
    "Aah! That was too close to my hammer and sickles."
  • Unwitting Pawn:
    • Dempsey, Nikolai, and Takeo as of the events during Moon.
    • As are the Green Run group.
    • The ''Origins' group is this for a while until Richtofen reveals his plans of killing their WW2 counterparts to avoid the collapse of the dimensions.
  • Villain Song: "Not Ready To Die" appears to be Dr. Richtofen's. A number of the series' songs seem to apply to Samantha, but "115" appears to be the main one and the one the fits the trope most.
  • Vitriolic Best Buds: Everyone insults everyone, but they'll help them, anyway. In fact, the characters themselves are programmed with different reactions to their teammates. They each have one teammate who they are friendly and hostile to, as well as one who they do not react to at all. For example, Dempsey likes Takeo, does not react to Nikolai and hates Richtofen.
    "Fidel's down. EVERYONE POINT AND LAUGH!"
  • Verbal Tic: Tank Dempsey says "Oorah" more times than the combined "Hooahs" of Modern Warfare 2!
    • He also calls ammo "gun juice", which happens a lot when you run out of ammo or get max ammo, resulting in-
  • Vodka Drunkenski: Nikolai, obviously. Lampshaded.
    Nikolai: Nothing is more dangerous than a drunk Russian with an MG!
  • Wham Episode:
    • The Easter Egg on Moon, Richtofen's Grand Scheme.
    • Buried. Dr. Maxis' Easter Egg makes everything worse, with the further destruction of Earth.
    • Der Eisendrache. Ritchtofen reveals that he is hunting their older versions to hopefully save all dimensions from the zombies.
    • Gorod Krovi. Dr. Monty finally shows himself and reveals some future plans.
    • Revelations. The Shadow Man is the enforcer of the Apothicons. And he's loose in the perfect world.
  • Where It All Began: Happens in each season.
    • The World at War season concludes in Der Riese, the original base of Group 935 where the zombies were first created by humans.
    • The Black Ops season concludes in Moon, which is where Richtofen first used the teleporter years ago, and where he learned of the Aether and first came into contact with it.
    • Black Ops II concludes with Origins, which details how the Origins incarnations of the characters met - though it's also literally the jumping off point for a new timeline of the story.
    • Black Ops III and potentially the entire series concludes with Revelations, which takes place not just in a map partially made of an amalgamation of Nacht, the first ever map, but also centers around "The House", a perfect dimension created by Monty to restart the universe from. In a way, the series begins in a house, and ends with The House.
  • Your Costume Needs Work: In Call of the Dead, George A. Romero tells a real zombie to get back to hair and make up because they "don't look dead enough". Said zombie is missing his lower jaw and is very decayed.
  • Your Princess Is in Another Castle: Moon's description makes it seem like it's the last map... Then Richtofen's Grand Scheme kicks in....
  • Your Head Asplode: Headshotting zombies with most guns will cause their head to explode into a mess of rotten gunk. Although if the zombie is strong enough, it'll likely just piss them off, but given that they don't survive for long without their heads and can be killed with a single shot from anything in such a state it isn't too much of a problem.
  • Zombie Apocalypse: Implied via radio messages.
    • It's reached the Pentagon during JFK's term as President.
    • Outright shown in Black Ops II. The main storyline is about surviving one.

Alternative Title(s): Nazi Zombies
