Caldera

Caldera is a map available for Call of Duty: Warzone. The map was released on December 8th, 2021 with Season One of Call of Duty: Vanguard replacing Verdansk as the main map for Warzone.

History

As part of an operation for a possible front in the Pacific, the Germans invaded the island of Caldera in 1939 and occupied it for several years. As part of Project Phoenix and the advent of the Fourth Reich, Nazi scientists began the development of Nebula V on Caldera and the nearby islands with the intent to use the chemical weapon against the Allied Powers using V-2 Rockets

In December 1944, the SOE launched Operation Vulcan after rumors of German activity on Caldera. Carver Butcher oversaw the operation, personally transporting Task Force Trident led by Francis Lanakila and comprised of Isabella Reyes and Lewis Howard to the island. However, the Germans spotted the plane and shot it down. Carver ordered Trident to jump out while he crash-landed on a beach. The task force regrouped and began looking for Butcher who discovered a hidden bunker near the crash site. Inside the bunker, they discovered intel regarding Nebula V and learned of a stockpile hidden within a medieval castle in the Alps.
