"Atlas's new pet broke out of the lab and infested an entire compound. Fight with up to 4 players to survive against endless waves of mutant zombies!"
— In-Game Description

Outbreak is the first (chronologically the second) Exo Zombies map featured in Call of Duty: Advanced Warfare. This map takes place in a secret Atlas research facility that has been overrun by zombies.


In Outbreak, the player first starts out with no Exoskeleton, an Atlas 45, and 4 frag grenades. They must open doors to get to the Exo Testing Room to obtain the exoskeletons. Most areas of the map have a power switch that needs to be activated in order to turn on the different Exo Upgrades located around the map, which are similar to Perk-a-Colas from Treyarch's Zombie mode. The randomized 3D Printer, which is similar to the Mystery Box from Treyarch's Zombies, has five locations, but only one is active at a time. There are two Upgrade Stations, which are also similar to the Pack-a-Punch Machine from Treyarch's Zombies, that allow weapons to be upgraded up to 20 times (25 upon the easter egg completion). There is also a Decontamination Zone, which will cure players that have been infected by Hosts.

The starting area features a Bulldog and MK14 printer for 500 credits each, similar to the starting weapons in Call of Duty: Black Ops and Call of Duty: Black Ops II.



The starting location, located outside the facility. The Courtyard is a quite large and open area, with a bus located in the center of the zone. Zombies spawn from three areas on the rooftops, from three windows and from below the bus. There are two doors in this area that can be opened for 750 credits each, leading to the Administration and the Main Hub.

Weapons available:


  • Power Switch, behind the player when spawning. Gives access to the Exo Medic upgrade.
  • Exo Medic - 500 credits (solo)/1500 credits (multiplayer), by the door to the Administration
  • the crashed Warbird's black box that's required for the main easter egg on Outbreak

Main Hub[]

The Main Hub is the center of the facility. It is a large, circular area with a smaller circular booth in the center. Zombies will fall from the rooftop, and can be chained by making a circle around the middle booth, or go through the booth to entercept the player(s). The Main Hub has three doors, one connecting it to the Courtyard, and two others connecting to the Morgue and the Hold.

Weapons available:


  • Power Switch, in the booth
  • 3D Printer - 1000 credits per use, location in the booth
  • Exo Slam - 2000 credits, on the wall near the door leading to the Administration


The Morgue is a large area, comprised of a small hallway connected to the Main Hub and the Administration, and a larger room, connected to the Exo Testing room. Zombies will spawn from multiple windows here.

Weapons available:


  • 3D Printer - 1000 credits per use
    • in the hallway (initial spawn)
    • Below the staircase leading towards the Exo Testing Room
  • Power Switch, on a wall facing the staircase
  • Exo Reload - 2000 credits, close to the HBRa3 in the upper level of the Morgue

Exo Testing Room[]

The Exo Testing Room is the central part of the map. It contains the exoskeletons for players. It is a large area with catwalks around most of the room. Zombies can be chained by running around the catwalk, but it may be tough with a number of possible entrances and the gap. It is connected to the Morgue and the Hold. In order to obtain the exoskeletons, the player(s) must turn on the power generator near the Morgue entrance. Once done, the security glass will be disabled and the exoskeletons will be available for free.

Weapons available:


  • Power Switch - Below the Morgue entrance
  • 3D Printer - To the right of the staircase leading towards the Morgue
  • Trash Chute - Next to another staircase leading towards the catwalks, leads the payer to the Courtyard
  • Upgrade Station - 2500 credits per use, spawns only upon completing the easter egg, in the main room. Can only be used to upgrade a Mk 20 weapon to Mk 25


The Administration is a room located between the Morgue and the Courtyard. It is where the Decontamination Zone can be found, in a corner close to the Courtyard door. The area is rather narrow, and players may easily end up stuck at higher rounds here. Zombies will spawn from multiple windows here.

Weapons available:


  • Upgrade Station - 2500 credits per use, close to the Decontamination Zone
  • Trash Chute - facing the Upgrade Station. Takes the players to the Exo Testing Room


Located between the Main Hub and the Exo Testing Room, the Holding area is an area with narrow corridors and a larger room with holding cells. It can be accessed from both the Main Hub and the Exo Testing Room. There is also an upper level, which can chain zombies. Zombies will spawn from multiple windows here.



  • Upgrade Station - 2500 credits per use, in a small room close to the Main Hub door
  • Power Switch - in the same room as the Upgrade Station
  • 3D Printer - 1000 credits per use, in the room to the left when entering from the Main Hub
  • Exo Health - 2500 credits, in a room behind the holding cells room, next to a staircase
  • Exo Soldier - 1750 credits, in a room near the Exo Testing Room door

Easter Eggs[]

Main Quest[]

Main article: Game Over, Man!

The Main Quest in Outbreak is Game Over, Man! which involves the four survivors' attempt to call in a rescue chopper for evacuation.

Musical Easter Egg[]

The musical easter egg of the map is Ride of the Valkyries from Richard Wagner's Der Ring des Nibelungen which can be activated by interacting with three items on the map, with a few notes from the song being played when done correctly:

  • The first item is in the Administration. It is a wrench sticking out of a crack in a white wall next to a sign near the MP11.
  • The second item is in the Exo Testing Room. It is a bonesaw on a table behind two mostly closed doors.
  • The third item is in the Holding, in one of the rooms on a bed with a corpse. The item looks like a flat iron.

Opening Scene Transcript[]


A view of the front yard of the Atlas research facility is seen, as Oz narrates.

Oz (narrating): When Atlas dropped the bomb, they... hoped it would finish the war. Instead, it unleashed a freak show like no one's ever seen.

The scene then shifts to a prison, showing an unnamed Atlas soldier attempting to escape a horde of zombies, with Gideon aiding him from a Warbird after reaching the prison's courtyard. As Gideon looks at the zombie horde swarming the prison, he is suddenly pulled out of the Warbird by a zombie.

Oz (narrating): Three platoons were sent in to cage their new pet. Two came back in body bags. An acceptable loss by Atlas standards.

The scene then shifts to the Atlas research facility, at night. Oz is seen doing clean up duty.

Oz (narrating): Then they brought them here... for research. Gotta get a return on your investment.

Oz then notices streaks of blood, coming from several broken glass casings, as well as three dead bodies. The scene zooms in on one of the casings. A hand suddenly appears, and cracks the glass.

Oz (narrating): No one bothered to tell the rest of us.

The scene switches to Lilith, who is working at her desk. An alarm then sounds, drawing Lilith's attention.

Lilith: What the hell? There is no Sub-Level 6.

The monitor in front of Lilith displays "Access Denied".

Lilith: *sighs* Execs do love their secrets.

She begins to type on the virtual keyboard. The screen then says "Access Granted". A second screen to her right then displays security footage, showing a zombie eating an Atlas employee's guts.

Lilith: Oh no.

The zombie notices the security camera, and lunges at it. The scene then switches to Kahn, who is viewing the same footage in his office. He then picks up his phone.

Kahn: You gotta be fucking kidding me. (on phone) Arlene, get me security.

Kahn looks outside, and sees a the second level of a building block in the facility explode.

Kahn: No, all of it!

The scene then switches to Decker, who is helping the Atlas employees evacuate.

Decker: This is a Code 3 evacuation. Remember the drill! Stay together, and try to-

Decker then sees the zombie horde coming toward him.

Decker: Son of a bitch!

Decker then makes a run for his life as the zombies swarm in. The scene shifts to a view of the facility, with explosions across all floors. Zombies are shown running amok, outnumbering the remaining Atlas operatives.

Oz (narrating): No warning... No backup...

A Warbird arrives at the landing zone, but is then attacked by multiple zombies.

Warbird Operator: Approaching the landing zone and-

Oz (narrating): No one left...

Warbird Operator: What the hell!?! Get it off! Get it-AGGGHHHHH!!!

The Warbird then crash-lands as Oz, Lilith, Decker and Kahn arrive for their evacuation.

Oz (narrating): ...But us.

The camera then zooms in on Oz.

Oz: I fucking hate the Atlas Corporation.

The four survivors prepare their pistols.
