"Here at Broken Arrow, it is our Mission to Prepare for Humanity's Future and Open New Worlds..."
— Mission Briefing
Alpha Omega is the seventh Zombies map featured in Call of Duty: Black Ops 4, and the thirty-first map overall. The map was released on July 9th, 2019 on PlayStation 4, and was released on July 16th, 2019 for Xbox One and PC. It serves as the penultimate map of the Aether Story.
Alpha Omega is a reimagined and remastered version of Nuketown Zombies. Set at the Broken Arrow facility prior to what was thought to be a nuclear explosion that leveled the testing site, Alpha Omega greatly expands on the original predecessor, adding new areas such as the other houses before the cul-de-sac, and allowing players to access the large underground bunker and research facility that resides below the surface. Players will have the ability to play as both Primis and Ultimis characters, though there cannot be two of the same character, such as a Primis and Ultimis Dempsey being present. The map also re-introduces the Ray Gun Mark II, this time with the ability to be upgraded into four variants, each of which possess their own special abilities. The Galvaknuckles from Call of Duty: Black Ops II also return in this map, costing 5000 points as opposed to the original 6000.
The central Easter Egg for Alpha Omega is Electromagnetic Awakening Party which tasks the combined forces of Primis and Ultimis to begin to enact the plan of Primis Nikolai from his reading of the Kronorium, Beginning at a nuclear test site in Nevada.
Several different four digit codes can be inserted into Rushmore, which can be used to activate small hidden easter eggs.
The player can activate Sergeant A.D.A.M., who acts similar to the Civil Protector from Shadows of Evil. He can be activated by finding the four authorization codes and inputting them into Rushmore.
Operation Toy Soldier Code - On a clipboard beneath the world map in the Operations house. This one is always the same 7626.
Sawyer Code - On a desk to the left of the Saug 9mm, in the corner on the other side of the room to the left of the door to the street, and upstairs on the console at the back of the room in the APD Interrogation house.
McCain Code - Under a stack of papers on a console next to the blast doors within the APD Control. Melee or shot the stack of papers to reveal the code.
Pernell Code - In the drawer of the desk on the second floor of the Yellow House. Requires a key to open, which can be found in a key box in the small office in Solitary.
Shooting off all of the A.D.A.M. heads around the map will cause the next round to consist only of A.D.A.Ms. After completing this round, the player will be rewarded with a free perk, which can be collected in front of the Nuketown sign.
Knifing off all of the A.D.A.M. heads around the map will summon a "weeping angel" A.D.A.M., who will constantly follow the player around, but will freeze in place when looked at. This particular A.D.A.M. is immune, and will only disappear by reuniting it with a female A.D.A.M. in the Generators. From there, the two will enter the upstairs shed and reward the player with a self-revive.
Knifing off all of the A.D.A.M. heads around the map with Galvaknuckles will spawn an A.D.A.M. next to the Pack-a-Punch Machine. Upon aiming at it, the player will trigger a jumpscare of an A.D.A.M. head.
There is a lone A.D.A.M. located in the desert behind the Green House, and aiming at it with a sniper scope will trigger a jumpscare.
It is revealed in the final cutscene that while it was severly damaged by it, it was not the nuclear explosion that destroyed Camp Edward, but rather Samantha, who destroyed the entire facility upon emerging from a teleporter upon witnessing her father's death.
If the player uses Theater Mode and remains aboveground when the nuke goes off, it will come to light that nothing has changed.
