Operation Flashpoint: Red River

Players take control of Outlaw-2-Bravo, a US Marine Corps fireteam, during a fictional conflict in Tajikistan in 2013. A terrorist group known as ETIM launches mortar attacks on a US FOB in Afghanistan, prompting the US to launch operation Enduring Shield and invade west Tajikistan. Later, the People's Liberation Army of neighbouring China intervenes and attacks both American and terrorist forces.

The game also offers the choice of playing the campaign cooperatively.
