Then a mercenary army sinks an oil tanker carrying another 600-ton amphibious tank that leads to the construction of a oil clean up facility off the coast of New York. When the President of the United States visits to inspect the facility a terrorist group calling themselves the Sons of Liberty will than hijack the facility and hold the President hostage. Threaten to destroy the facility which will result in the world's greatest ecological disaster and a nuclear strike unless their demands are met. It will later turn out that the leader of that terrorist group happened to be a former President who fell out of favor of a very secret organization. Underneath is the threat of humanity's existance, a submarine that is 1000x times larger than the ballistic submarines, with a payload of nuclear warheads and more 600-ton amphibious tanks. And yes I have played Metal Gear Solid 2: Sons of Liberty waaaaay too much too.
