- "Survive the Zombie hordes alone or cooperatively. Repel wave after wave of increasingly deadly Zombies in a number of frightening locales. But be warned: there are more than just Zombies lurking these dark hallways..."
- — Call of Duty: Black Ops game manual description
Zombies, originally known as Nazi Zombies, is a game mode mostly appearing in Treyarch games that first appeared in Call of Duty: World at War. It became highly popular upon the game's release, and returned in its sequels Call of Duty: Black Ops, Call of Duty: Black Ops II and again in Call of Duty: Black Ops III. In Zombies, players face zombies of various nationalities depending on the location of the map, including Germans, Americans, Russians and Asians. Zombies content is only considered canon in its own universe.
Up to four players, eight on Grief, must survive endless waves of attacking zombies, earning points from killing or damaging zombies and repairing barriers. These points can be used to purchase weapons and Perk-a-Colas in the process, or unlock new areas and activate other special objects. Zombies enter the player-accessible area of the map via windows, holes in walls, or climbing out of a "dirt" surface, which are initially barricaded but will be rapidly demolished by zombies. They can be repaired, however, with the exception of the dirt surfaces. There is no limit to the number of rounds; the game will end when all players have been incapacitated or killed by the Zombies, or if the player completes Pop Goes the Weasel on Mob of The Dead, or Little Lost Girl on Origins. Zombies become stronger and faster upon the completion of each round, forcing players to make tactical decisions about point spending and progressing through the map. On occasion, zombies will drop power-ups such as Max Ammo, Nuke, or Insta-Kill upon their death, making the round easier.
Altogether, Zombies consists of seventeen maps; the first, second, fourth, fifth, and seventh feature Nazi Zombies (Nacht der Untoten, Verrückt, Der Riese, Kino der Toten, Dead Ops Arcade), while the third features Imperial Japanese Army (Shi No Numa), the sixth features American civilians, military and scientists ("Five"), the eighth features Soviet scientists, cosmonauts and military (Ascension), the ninth features Siberian sailors and divers (Call of the Dead), the tenth features Himalayan civilians (Shangri-La), the eleventh features Astronauts and American military (Moon), the twelfth features various American civilians (Green Run), the thirteenth map features Russian Spetsnaz and American Zombies of various afflictions, including zombies wearing hazmat suits (Nuketown Zombies), the fourteenth features Chinese civilian and military Zombies, (Die Rise), the fifteenth features American prisoners and guards (Mob of the Dead), the sixteenth features Western barmaids, prospectors and cowboys in a continentally-shifted Angola (Buried), and the seventeenth features WWI era German soldiers and Medieval Templars in occupied France (Origins).
So far, Zombies has a total of 94 playable characters (including various unidentified ones).

Zombies is also known for carrying on the tradition of odd Easter Eggs within Call of Duty games. Some of the maps have "major" Easter Eggs, almost campaigns, which upon completion, grant the player(s) an achievement/trophy, in addition to an in-game reward, usually in the form of weapons or perks.

- Main article: Nacht der Untoten
- "You drove them deep into the heart of Reich. You thought they were dead. You were wrong."
- — Nacht der Untoten description
Nacht der Untoten (German: "Night of the Undead") is the first map of the Zombies Campaign. It is also the smallest and simplest, as there are only three rooms in this map. The Zombies in this map are less deadly than the ones in other maps, as they do not reach through windows and they're the least smart in terms of AI. The Zombies also look more human in this map and they just groan and moan. This was the only map to not include Perk-a-Colas until the September 27, 2011 update that provided every map with Mule Kick, however, this only applies to Call of Duty: Black Ops. Because it is a last minute developer addition, this map simply acts as an introduction to the Nazi Zombies Game Mode and does not advance the Zombie Story Arc; it's more along the lines of an isolated incident for four unnamed soldiers. It takes various design elements from a bunker in the multiplayer map Airfield. The version in Call of Duty: Black Ops features the original power-ups, including the Carpenter power-up (which was first introduced in Der Riese) including the power-up icons, instead of the text and the remaining time at the bottom. Cold War weapons are available in the Mystery Box, zombies can now reach through the windows to hit the players, and a new musical easter egg called "Undone" can be found.
- Main article: Verrückt
- "Electroshock therapy. Chemically engineered beverages. Hordes of Undead Nazis. Find the power to unite and send them back to their graves!"
- — Verrückt description
Verrückt (German: "Crazy/Insane") is the second map in the Zombies campaign. It is based on the multiplayer map Asylum, as they share many traits. The zombies in it are much more dangerous because they can attack through windows and can sprint. This is also the first map to include traps, Perk-a-Colas, and Bouncing Betties, as well as the first map to require the power to be turned on. There are ten rooms in this map, which require points to open. This is the first map where the Mystery Box can be teleported by the teddy bear and reappear somewhere else. This map takes place in Wittenau Sanatorium in Berlin, Germany, and this is the first map to feature different factions. There is a German and American side, each with the faction's respective weapons. When playing with three or four players, they will be split up and have to reunite at the generator room unless two people activate the power, after what the door connecting the two starting areas oen. This map also introduces the PPSh-41, available from the Mystery Box. In the Call of Duty: Black Ops version of this map a new Wonder Weapon, the Winter's Howl, is introduced.
- Main article: Shi No Numa
- "Maggot ridden corpses. Bug infested swamp. Hundreds of undead Imperial Army. Choose your tactic and defend for your lives!"
- — Shi No Numa description
Shi No Numa (Japanese: "Swamp of Death") is the third map in the Zombies Campaign, and is the first not to feature Nazi Zombies. The maximum Zombie running speed has been reduced from a full sprint back to the original running speed, possibly for difficulty reasons. There are five main buildings in this map and four unlockable swamp areas connecting these buildings. Four of the buildings contain only one room, while the main building has three. This is the second map where the electricity does not have to be turned on. This map, along with Shangri-La and Moon, has Perk-a-Cola Machines that spawn randomly. This is also the second map where the Mystery Box can move, with a new feature: a yellow beam above the place which it has spawned. Players can now walk outside of buildings without glitching or cheating and zombies can spawn next to them without bypassing a barrier. The Zipline utility is introduced here, and returns in Call of the Dead. There are now special rounds in which the players ward off Hellhounds, a newly introduced enemy and are awarded with a Max Ammo afterwards. It is also the first map where the individual identities of the players are known. Shi No Numa also introduces a new Wonder Weapon, the Wunderwaffe DG-2, an electricity-casting weapon that can kill up to ten zombies at once, in a chain reaction. This map is also the only one with the Flogger, a manually activated trap. In this map, the Zombies backstory unfolds for the four main characters, Tank Dempsey, Nikolai Belinski, Takeo Masaki, and Edward Richtofen. This is the first map that does not take design on a map built into the game.
- Main article: Der Riese
- "The Giant is rising. Face the might of the Nazi Zombies in their heartland. This is where it all began. This is where the master plan took shape. Is this where it all ends?"
- — Der Riese description
Der Riese (German: "The Giant") is the fourth map in the Zombies Campaign. It takes some features from the multiplayer map Nightfire. It is the first map where zombies can climb over areas and jump down from an area towards the characters. It also introduces the Pack-a-Punch Machine, which for 5000 points upgrades weapons to have increased ammo capacity, more power, higher fire rate etc. It is the second map where the power is required to be switched on. Der Riese is the third map where Perk-a-Cola machines are included, and the second where Perk-a-Cola machines do not spawn randomly. Der Riese is the second map to contain hellhounds, which spawn about every five rounds. It is the first map to have Teleporters, the Monkey Bomb, the Bowie Knife, and the Fly Trap. It is the second map where the identity of the characters are known, and sub-sequentially advances the plot. It is the second to have a small objective, which is turning on the power and connecting the three teleporters to the mainframe to access the Pack-a-Punch machine. Der Riese also features the new "Carpenter" power-up, which boards up all opened windows in the level and award the players 200 points. It is the first of two maps in which Hellhounds spawn alongside Zombies. This occurs after the third Hellhound round sometime after round 16. This map is set in Germany, near Breslau. One can also learn the story behind the zombies by turning on radios' hidden throughout the map by pressing the action button near the radio.

Kino der Toten (German: "Theater/Cinema of the Dead") is the fifth map in the Zombies Campaign, introduced in Call of Duty: Black Ops. The four original characters are playable. It has almost all the features from Der Riese, including the Bowie Knife, Teleporters, Pack-a-Punch Machine, Hellhounds and Monkey Bomb, although the Wunderwaffe DG-2 does not return. A new Wonder Weapon, the Thundergun, makes its debut, replacing the Wunderwaffe DG-2. It is the first map to have purchasable Cold War weapons, as well as the first map to have the new Gas Zombies. It is the third map to require the electricity to be turned on, and is the first Zombies map to not have the Mystery Box spawn in a fixed location. It is also available on the iOS version of Call of Duty: Black Ops Zombies. This map is set in an abandoned theater in Berlin, some time before 1963.

By doing this, the player will also unlock the "Insert Coin" achievement for 5G or a bronze trophy, and can access Dead Ops Arcade from the Zombies menu. This map plays no role in the Zombies plot. 50 levels of Dead Ops Arcade are featured on the iOS version of Call of Duty: Black Ops Zombies.

Double Tap Root Beer doesn't return, but was initially set to appear. Space Monkeys have replaced the Pentagon Thief and Hellhounds. There is a new power-up introduced here, the Random Perk Bottle, which grants the player a random perk. Two new Wonder Weapons made their debut, the Gersch Device and the Matryoshka Doll, both of which are tactical grenades. The Bowie Knife is not in this map, as it is replaced by a Russian counterpart (only for aesthetic purposes), the Sickle which works exactly the same. The four original characters, Tank Dempsey, Nikolai Belinski, Takeo Masaki, and Edward Richtofen return. It is the second map where players can have zombies spawn next to them. It is the only map with the Lunar Lander, a utility that works similarly to the Teleporter. It is the fifth map where the electricity is required to be turned on. This map features Russian cosmonaut, scientist, military and civilian zombies. However, gas zombies do not return. This map also advances the zombie storyline much more than the previous Call of Duty: Black Ops map Kino der Toten. This map includes more radios similar to the ones in Der Riese and the Kassimir Mechanism Easter Egg which advances the story of Samantha Maxis as a demonic being. Characters from "Five" can be heard on this map by using the three red telephones, indicating that the two maps occur simultaneously. The map is based on Launch. Ascension is also available on the iOS version of Call of Duty: Black Ops Zombies.

On November 16 2009, Nazi Zombies was released for the iOS as an application for £6.99 (UK) and $9.99 (US). Originally, only Nacht der Untoten was available to play, but Treyarch confirmed that other maps would be released in the future. Verrückt was released for £2.99 and $4.99 on February 11 2010. The iOS version have lower quality graphics than their console counterparts, but they do include leaderboards, unique Achievements and 3 different control schemes. The game also includes an Aim-Assist like feature, as the camera will snap onto nearby targets, even from the hip. On June 2, 2010, version 1.4 was released, and along with it, Shi No Numa, the third map to be released for the iOS also for £2.99 and $4.99. As of September 30, 2010, version 1.5 was released and includes Der Riese, the fourth map, for no additional payment, new achievements, better zombies AI, improved graphics, the previous two maps were also made free, and made the app itself £2.99 and $4.99.
Call of Duty: Black Ops: Zombies was released for the iOS for £4.99 (UK) and $6.99 (US) on December 1, 2011, and August 2012 on Android. The application features Kino, Ascension, Call of the Dead: Director's Cut & Dead Ops Arcade. It boasts four player online (Local Wi-Fi only on Android) as well as new voice chat, which utilizes the device's internal microphone. It is also the first time one can choose from the four original playable characters. The controls are similar to its predecessor, but appearance has changed drastically to a comic book-style theme based off the consoles version's loading screens. Dead Ops Arcade is unlocked after finding four hidden coins in the main menu screen (similar to how it is unlocked in the console version). It includes 50 levels, 10 more than on consoles, as well as all of the power-ups featured in the original.
Players that bought the Hardened or Prestige editions of the game or the Rezurrection map pack have access to the original four maps. The maps have had updates to their graphics and Cold War-era guns added to the Mystery Box. The four main characters have been added to all of the original maps, replacing the unnamed Marines.
All games come with Kino der Toten automatically unlocked, while "Five" is unlocked once the player completes the campaign on any difficulty. Dead Ops Arcade is unlocked once the player enters a code in the terminal. The First Strike map pack includes the level Ascension, the Escalation map pack includes Call of the Dead, the Annihilation map pack includes Shangri-La, and the Rezurrection map pack includes the level Moon with the four Nazi Zombies Maps from Call of Duty: World at War.
There is a Zombies Mode for the Nintendo Wii edition of Call of Duty: Black Ops. The only map available is Kino Der Toten, in which the graphics are scaled down in quality. A patch hinted to the release of "Five" and Dead Ops Arcade for the Nintendo Wii as it contained images of them contained in folders marked "dlc1", "dlc2", "dlc3", however, they were never released.
Zombie Mode appears on Call of Duty: Black Ops (Nintendo DS), in a similar format to the consoles. The concept of the game and many mechanics are the same, but many changes have also been made, such as an increase in damage from the zombies (able to down the player in one hit at round one), an increase in zombies' health, more points needed to buy weapons and doors (players are awarded more points for kills) and barrier mechanics (cannot be repaired while being destroyed, zombies able to attack when mantling the barrier, barriers are broken down and repaired faster).
- The House — Abandoned house in the North.
- The Facility — Abandoned research facility.
- The Temple — Remotely located temple.
- Overlook — Abandoned outpost.
Zombies Mode returns in Call of Duty: Black Ops II. The mode now supports up to eight-player co-operative in Grief and runs on the game's multiplayer engine, rather than a modified singleplayer engine as in Call of Duty: World at War and Call of Duty: Black Ops. It also supports four-player co-operative split screen.
Additionally, a promotional poster for the game depicts a woman, now known as "Misty", wearing plaid shirt, a trucker hat with the number "1221" on it, a sheathed sword, a Winchester Rifle, and a decapitated head of a zombie.
The story appears to follow a group of four survivors: Abigail "Misty" Briarton, Marlton Johnson, Samuel Stuhlinger, and Russman, surviving the events following the destruction of Earth in Richtofen's Grand Scheme in the American South-West, and must fight the nationwide apocalypse to survive the harsh environment. Elsewhere, U.S. surviving government factions CIA and CDC (Center for Disease Control) must combat each other to gain the upper hand in survival with the zombies.
Later on, this group is teleported to China, where they survive against SDC and Chinese civilian zombies.
In another downloadable map, Mob of the Dead, four mobsters imprisoned in Alcatraz, Finn O'Leary, Albert Arlington, Salvatore DeLuca and Billy Handsome, fight off the endless waves of the undead in the 1930's. This map is the first map to have an actual ending, without being killed by zombies.
In the next map, the 4 original survivors travel to Africa, where they survive in an underground western town against old western zombies.
The final map has the four original characters, Tank Dempsey, Nikolai Belinski, Takeo Masaki and Edward Richtofen meeting for the first time and fighting off zombies at a battlefield in Northern France.
Numerous choices are now given to the player in lobbies such as what round to start on (1, 5, 10, 15 or 20); enabling or disabling Hellhounds; turning power-ups and other "supernatural" advantages (called "Magic") on or off; as well as headshots only. An "easy" difficulty is also given in addition to the original.
Theater mode is also introduced in to Zombies, similar to the one in multiplayer.
The maximum amount of points a player can have in a match is 1,000,000 points.

A ranking system is a new feature that was introduced in Call of Duty: Black Ops II. It has a total of five levels, a bone, a cross bone, a skull, a skull stabbed with a knife and a skull with two shotguns.
There is not a clear explanation on the emblems' requirements, although numbers of ways have been speculated. Generally, consistent good performance is rewarded, including high rounds survived, kills and lack of downs. The player can get demoted to a lower rank for lowering their performance, typically by going down often at low rounds.
The tally marks on the emblem depend on the player's recent activity. The player will get a tally mark each day they play at least one match. Not playing will reduce one tally mark per day.
- In Call of Duty: Black Ops, only a maximum number of 24 zombies can be alive at one time. A larger amount can be alive in Call of Duty: Black Ops II. If a zombie cannot hit a player within a certain amount of time, the zombie dies, allowing another zombie to spawn. In Call of Duty: World at War, only 24 Zombies can be on the map in an entire round, with the exception of Der Riese. This makes getting to higher rounds much easier.
- The music that plays when each round ends on all maps (except in Mob of the Dead, Buried, Origins and the Call of Duty: Black Ops on DS maps) is heard in Hell's Gate, a track from Call of Duty: World at War soundtrack.
