This will be the first time that a Zombies storyline has continued across different studios with Sledgehammer and Infinity Ward trying their hands at the mode in WW2 and Infinite Warfare, respectively. With Treyarch working on the Zombies mode for the upcoming Call of Duty: Vanguard, it has already been confirmed that game's Zombies story will be a prequel to what we have seen in Cold War.

Samantha Maxis, a pivotal character from the original story, is caught in the middle as she slowly becomes a weapon, with her allegiances being tested at every turn. The forces within this unknown world have plans of their own, however. The story so far in Cold War has seen two factions, Requiem and Omega, attempting to use this alternate dimension known as the Dark Aether in a new arms race.

Cold War's "Dark Aether" storyline is a soft reboot of the original "Aether" story that most fans of Call of Duty are familiar with that ran from World at War all the way to Black Ops 4.
