Summary. Call of Duty: Modern Warfare 3 continues the series' reboot, offering a variety of multiplayer modes, a campaign, and Zombies mode.

Treyarch, the lead developer behind the Black Ops sub-series, were also tasked with creating a Zombies mode for Modern Warfare III, making it the first Modern Warfare title to feature a Zombies mode.

Russian Ultranationalist Imran Zakhaev, who plans to return his homeland to the times of the Soviet Union, draws international attention away from his plans by funding a coup d'tat in an unnamed Middle Eastern country, organized by a local separatist leader named Khaled Al-Asad.

The game's story follows the United States Marine Corps (USMC) and the Special Air Service (SAS), who take on missions to fight against a separatist group in the Middle East and an ultranationalist group in Russia. Development began after an online petition requesting a Modern Warfare remaster began circulation.
