Call of Duty: Black Ops 6 is a 2024 first-person shooter video game co-developed by Treyarch and Raven Software and published by Activision. It is the twenty-first installment of the Call of Duty series and is the seventh main entry in the Black Ops sub-series, following Call of Duty: Black Ops Cold War (2020). Set during Operation Desert Storm, Black Ops 6's single-player story follows rogue CIA operatives Troy Marshall and Frank Woods as they assemble a team of agents to hunt down Pantheon, a paramilitary group with covert ties to the agency. As with previous Call of Duty titles, the game also includes a multiplayer component and the cooperative round-based Zombies mode. Black Ops 6 had a four-year development cycle—the longest in Call of Duty history; a portion of the game's production was spent on rebuilding core aspects of Black Ops within the latest version of the Call of Duty game engine. An omnidirectional movement system was also introduced, allowing players to sprint, dive, and slide in any direction. Marketing for Black Ops 6 began in May 2024, through the release of live-action teaser trailers and the publishing of advertisements on the front pages of multiple newspaper outlets; a full reveal debuted during the 2024 Xbox Games Showcase event on June 9. The game was released on October 25, 2024, for PlayStation 4, PlayStation 5, Windows, Xbox One, and Xbox Series X/S. Upon release, Black Ops 6 received generally favorable reviews from critics, achieved the largest launch weekend in the franchise's history, and was nominated for several accolades. All three modes were met with praise, with critics positively highlighting the new omnidirectional movement system. A sequel, titled Call of Duty: Black Ops 7, was released on November 14, 2025.
