It wouldn’t be a Call of Duty game without a Zombies mode, and that is exactly what Vanguard is getting courtesy of Treyarch.
The four-person co-op mode continues and expands on the Dark Aether story first experienced in Call of Duty: Black Ops Cold War. Set in World War 2 in the ruins of Stalingrad, Vanguard’s Zombies experience finds mortals bonding with Dark Aether entities to gain power.
According to the storyline, it all started with the opening of the Dark Aether gateway at Projekt Endstation where a Nazi experiment went wrong and caused a hole to form in the dimensional veil.
