Five years after the 'World Federation' was established strife and war are still on the rise. In order to keep the peace the Federation Armed Forces, part of the Federation Police, build fully armed, bipedal Mechs also known as 'Metal Heads'. The Metal Head's success causes a heavy militarization of the countries of the Federation. A sudden and chaotic revolution led by terrorists, armed with their own fully armed Mechs, breaks out and the terrorists take control of a whole country. The player character (in a Metal Head) is sent in with his team to liberate the country's capital. The player character starts in a small border town and works his way in to reach the capital.
