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 titles in the series, the game also includes a multiplayer component and the cooperative round-based Zombies mode; all three modes feature omnidirectional movement mechanics, allowing players to sprint, dive, and slide in any direction. Black Ops 6 boasts a four-year development cycle—the longest in Call of Duty history. Marketing for the game began in May 2024, through the release of several live-action teaser trailers and the publishing of fictional advertisements on the front pages of multiple newspaper outlets; a full reveal debuted following the airing of the 2024 Xbox Games Showcase event on June 9. Black Ops 6 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; critics positively highlighted the new omnidirectional movement system and the mission design of the game's single-player campaign.
