When Does the Warzone Map Change?
Although the Pacific Update also brings plenty of Call of Duty: Vanguard content to Warzone, including new weapons, operators and vehicles, the biggest draw by far is the new map: Caldera. This tropical island sports 15 named points of interest for players to explore, each with its own personality and loot profile.
The Pacific Update and the Caldera map have two different start times based on whether or not one has paid for a retail copy of Vanguard. Following a delay, Vanguard owners will be able to jump into Caldera and the rest of the update starting Dec. 8, but the rest of the world will have to wait for the full release the following day, on Dec. 9.
