Call of Duty

Call of Duty is a first-person shooter video game series and media franchise published by Activision, starting in 2003. The games were first developed by Infinity Ward, then by Treyarch, Sledgehammer Games and Raven Software. Several spin-off and handheld games were made by other developers. The latest game, Call of Duty: Modern Warfare 4, was released on October 23, 2026. The series originally focused on a World War II setting, with Infinity Ward developing Call of Duty and Call of Duty 2 and Treyarch developing Call of Duty 3. Infinity Ward's Call of Duty 4: Modern Warfare introduced a modern setting and proved to be the breakthrough title for the series, creating the Modern Warfare sub-series; a Modern Warfare remastered version was released in 2016. Two other entries, Modern Warfare 2 and Modern Warfare 3, were made. The sub-series received a reboot with Modern Warfare in 2019, Modern Warfare II in 2022, and Modern Warfare III in 2023. Infinity Ward has developed two games outside of the Modern Warfare sub-series, Ghosts and Infinite Warfare.
