Call of Duty: Warzone

Call of Duty: Warzone is a free-to-play battle royale video game that serves as a major component of the globally recognized Call of Duty franchise. Originally launched in 2020, the game was developed through a collaborative effort by internal studios including Infinity Ward and Raven Software. As a digital software product, its development and maintenance occur across various global locations, primarily in the United States, where the lead studios are headquartered.

The brand has undergone a significant ownership shift in recent years. While the Call of Duty series was created by Activision, the parent company Activision Blizzard was acquired by Microsoft in a historic transaction completed in October 2023. By 2026, the brand is fully integrated into the Microsoft Gaming ecosystem, operating as part of the Xbox division while maintaining its presence across multiple platforms including PC and PlayStation through long-term licensing agreements.
