Call of Duty: Black Ops 6 is a first-person shooter co-developed by Treyarch and Raven Software, published by Activision in October 2024. It is the seventh entry in the Black Ops sub-series, set during the early 1990s Gulf War era. The game features a single-player campaign, competitive multiplayer with an omnidirectional movement system allowing players to sprint, dive, and slide in any direction, and a cooperative round-based Zombies mode. It had the longest development cycle in Call of Duty history at four years, during which the team rebuilt core Black Ops systems in a new shared engine.
