was taken offline, the original Call of Duty: Warzone was re-launched under the new name Caldera.

During the game's downstream period, developers encouraged players to play "War Zone 2.0" for free.

As promised, the original War Zone has been quietly re-launched as Caldera, although as Isaac said before, in maintenance phase.

Caldera requires a standalone installation, and the Royal Four and Single Team are the only pairing modes. The in-game store has disappeared, but any purchases or unlocks are still accessible. COD points can be transferred between all games, but only the content and process of Modern Warfare 2019, the original War Zone, Black Ops: Cold War and Pioneer can be accessed in Caldera.

players have expressed their dissatisfaction with the deprived experience of "War Zone". Popular map Rebirth Island and wealth keeping is no longer available. Others want to see the raiding mode join Caldera.

The official website of Call of Duty has remained silent on Caldera's release, probably to continue to push players into Warzone 2.0. "War Zone 2.0" also has its own problems. On weekends, cheaters allow the boat to fly and use the vulnerability to brush experience points.
