Call of Duty: Warzone received a new update on November 4, which brings a few small fixes in the patch notes and gives players a brief glimpse of the recently announced Warzone Pacific map called Caldera. The new map will arrive with Vanguard’s Season 1 of content on December 2, but players can now view it in Verdansk by using a Red Door.
Warzone’s Red Door feature mostly works the same as before. These are the bright red and randomly spawning doors that emit a humming effect when close by. Interacting/opening one of these doors leads to a hallway of Red Doors, and there are usually 3 or 4 Red Doors in the corridor. All but one of the doors has a lightning effect around it, and players want to choose the one without lightning to get transported to a secret room filled with loot. Now with the update, players who use a Red Door will get a brief look of the Caldera map as they warp to the secret room.
