After the Global Economic Crisis causes mass unemployment and political destabilization in China, the PLA seize control of Skira and the vast, newly discovered reservoir of oil there, from the Russian Federation. Peace talks prove useless as both combatants lay claim to Skira due to previous ownership of it. The situation deteriorates quickly and China begins to fortify its northern provinces in anticipation of armed conflict with Russia.
Russia, already countering the PLA on the Chinese mainland, calls to the United States of America to retake Skira from the Chinese. Bound by treaty arrangements made after the end of the Cold War, America agrees and the two biggest armies in the world begin to clash on the island. As the game progresses, the player must fight off enemy forces along with his fireteam and allied soldiers, for example, this could be assaulting a village held by the PLA, suppressing a team pinning down your fellow soldiers, or rescuing downed crews of crashed helicopters from behind enemy lines.
