The story takes place in a fictional near-future, where a radical leader has staged a coup d’état in the Middle East, and an “Ultranationalist” movement has instigated a civil war in Russia. The events of the conflicts are seen from the perspectives of an American Marine and a British SAS commando, and are set in multiple locations, including the Middle East, Azerbaijan, Russia, and Prypiat, Ukraine.
