Call of Duty: Modern Warfare is a 2019 first-person shooter game developed by Infinity Ward and published by Activision. Serving as the sixteenth overall installment in the Call of Duty series, as well as a reboot of the Modern Warfare sub-series, it was released on October 25, 2019, for PlayStation 4, Windows, and Xbox One. The game takes place in a realistic and modern setting. The campaign follows a CIA officer and British SAS forces as they team up with rebels from the fictional Republic of Urzikstan, combating together against Russian Armed Forces who have invaded the country and the Urzik terrorist group Al-Qatala, while searching for a stolen shipment of chlorine gas. The game's Special Ops mode features cooperative play missions that follow on from the campaign. The multiplayer mode supports cross-platform multiplayer and cross-platform progression for the first time in the series. It has been reworked for gameplay to be more tactical and introduces new features, such as a Realism mode that removes the HUD as well as a form of the Ground War mode that now supports 64 players. A post-launch update introduces a free-to-play battle royale mode, Warzone, which was also marketed as a standalone title. Multiplayer also supports shared screen multiplayer. This mode includes bots, custom maps, custom game-modes and other creative game-interfering actions.
