Call of Duty: Warzone's story is a sprawling, multi-game narrative connecting Modern Warfare (2019), Black Ops Cold War, and Vanguard, focusing on the fictional city of Verdansk, torn apart by shadowy organizations like Perseus and Al-Qatala, leading to the rise of the Armistice alliance, its betrayal by Victor Zakhaev, and a massive chemical/nuclear conflict culminating in Verdansk's destruction by nuclear strike and the emergence of Zombies from a Soviet ship, all while linking past Cold War operations to present-day global chaos through characters like Captain Price and Adler.
