Call of Duty: Warzone is a free-to-play Call of Duty game developed by Infinity Ward and Raven Software for the Xbox One, PlayStation 4 and Windows.
Warzone is a component of Call of Duty: Modern Warfare and integrates content from Call of Duty: Black Ops Cold War and Call of Duty: Vanguard. The game featured three main modes, a Battle Royale mode, a Plunder mode, and a Resurgence mode added with the Season One of Black Ops Cold War.
With the release of the sequel Call of Duty: Warzone 2.0 on November 16th, 2022, the servers of Call of Duty: Warzone temporarily remained offline and returned on November 28th, 2022, with the game relaunched as Call of Duty: Warzone Caldera, only with the Caldera map with Battle Royale Solos and Quads playlists. On June 22nd, 2023, it was announced Warzone Caldera would be shutdown on September 21st, 2023.
In Battle Royale, players fight to be the last team standing. Warzone was released with squads of three players but on March 17th, a solo mode was added to Battle Royale followed by a 4-player Quads mode on April 8th. In addition to the loot found on the map and dropped by eliminated players, players can collect Cash to buy equipment or killstreaks from Buy Stations. Squads can also take on Contracts to get loot and Cash.
In Plunder, squads race to collect one million in cash. Each match only lasts 30 minutes. Unlike Battle Royale, players have unlimited respawns and redeployments and can spawn with their own loadouts and Field Upgrades.
Introduced with the Season One of Call of Duty: Black Ops Cold War, Resurgence takes place on Rebirth Island or Fortune's Keep and works similarly to Blackout's Down But Not Out mode. As long as a teammate is alive, players can redeploy after a countdown. They can redeploy 15 seconds after being killed during the first playzone and 39 seconds during the second and third playzones until the Rebirth Countdown runs out after 9 minutes and 15 seconds. After the timer has run out, players being killed will no longer be able to redeploy. Killing a player will also temporarily highlight their teammates on the mini-map.
