Call of Duty: Warzone is a free-to-play battle royale and large-scale multiplayer shooter developed by Infinity Ward, Raven Software, and published by Activision. First launched in March 2020, Warzone quickly became one of the world’s most played FPS games thanks to its dynamic gunplay, tactical movement and integration with the Call of Duty franchise.
 

Players drop into massive maps such as Verdansk, Caldera, Fortune’s Keep, Al Mazrah, Urzikstan and more. Each match features up to 150 players, with modes including Solos, Duos, Trios and Quads. Warzone offers a unique Gulag mechanic, allowing eliminated players to fight for a second chance to redeploy.
 

Warzone blends fast-paced Call of Duty gun mechanics with battle royale survival elements. Players scavenge for weapons, armor plates, contracts, killstreaks and cash to buy loadouts or revive teammates at Buy Stations. Customizable loadouts are a core feature, letting players create weapon builds with attachments, perks and tactical gear.
 

The game evolves through seasonal updates tied to mainline Call of Duty titles, including Modern Warfare, Black Ops Cold War, Vanguard and Modern Warfare II/III. Each update brings new weapons, operators, balance changes and limited-time modes.
 

Warzone also supports cross-play and cross-progression across all major platforms using an Activision ID, keeping player accounts unified. Its high-intensity gunfights, movement mechanics (slide canceling, plating, armor breaking) and cinematic presentation make it a leading free-to-play battle royale globally.
