The Front Mission saga focuses on the conflict over Huffman Island, located in the neutral zone between two superpowers known as the Oceania Community Union (O.C.U.) and the Unified Continental States (U.C.S.). Tensions between the O.C.U. and the U.C.S. spark the First Huffman Conflict in 2070, a two-year war ending with a ceasefire agreement that divides the island into two territories. After many years of relative peace, the sudden destruction of a U.C.S. military factory triggers the Second Huffman Conflict in 2090. 

Experience the war from the perspective of Royd Clive, the leader of the O.C.U. mercenary outfit "Canyon Crows" or Kevin Greenfield, the commanding officer of the U.C.S. Special Forces squad "Black Hounds". Battle through missions against wanzers, tanks, attack helicopters, and giant mobile weapon platforms, and unravel the true reasons behind the war over Huffman Island.
