A new Warzone map is a treat for players as we don't get many of them. After Verdansk, players got Verdansk '84 along with Rebirth Island for Warzone resurgence mode. We then received Caldera as the new map that came with the integration of Warzone and Vanguard on December 9, 2021.
We haven't received any new major map for Warzone ever since Caldera, but that is about to change with Season 4. Call of Duty has been hinting at a new Warzone map for quite some time now.
The new map was first teased on June 12, 2022, when the official Twitter account of Call of Duty tweeted the name of the map following a little "fill in the blanks" tease. The name of the new map was revealed to be Fortune's Keep.
Call of Duty continued to tease the new map by sending parts of the new map to different notable content creators, including JGOD, KRNG BearPig, KRNG Espresso, timthetatman, dysmo, rich, and many more. The creators were sent the map pieces in the form of a cake and digital copy to share with the players.
After the reveal of all the pieces, Call of Duty followed by revealing the complete assembled Tac Map of the new Fortune's Keep map coming to Warzone with Season 4. The map is going to be a Warzone resurgence map similar to how Rebirth Island is.
