Call of Duty: Modern Warfare 4 is an upcoming first-person shooter developed by Infinity Ward and published by Activision, slated for release on October 23, 2026, for Nintendo Switch 2, PlayStation 5, Windows, and Xbox Series X/S. As the twenty-third installment in the series and the fourth in the rebooted Modern Warfare sub-series, its campaign follows a war between North and South Korea, featuring protagonists Private Park Hyun Jun and the fugitive Captain John Price—who is on the run after assassinating General Shepherd—with missions spanning locations like New York, Paris, and Mumbai. The multiplayer mode introduces 12 core 6v6 maps, a revolutionary dynamic "Kill Block" map with over 500 configurations, and removes hipfire bloom, while adding new movement mechanics like hanging and shimmying. The extraction mode DMZ returns, placing 20 squads in a large "exclusion zone" with dynamic weather, a Forward Operating Base for gear prep, and permanent operator trait trees. Set in the South Korean exclusion zone of Hajin after a nuclear reactor meltdown, DMZ tasks players with recovering abandoned tech, all developed with assistance from Treyarch, Sledgehammer Games, and Raven Software.
