Story
Following
the events on Shadow Moses Island, Metal Gear's top-secret technology has
somehow been leaked into the black market through the machinations of Revolver
Ocelot. As a result, countless variations of Metal Gears have sprung up in every
corner of the globe, making the weapon an increasingly common component of the
armed forces and nuclear powers.
In the midst of all of this, Solid Snake, now a member of the anti-Metal Gear
group "Philanthropy," has learned that a new prototype Metal Gear has
been developed by the U.S. Marines and is being transported in secret to an
unknown destination.
To learn more about this new machine, Snake must infiltrate the transport,
rumoured to be disguised as a tanker, as it makes its way down the Hudson River.
Just as Snake is about to begin his mission, however, the ship is seized by a
mysterious and well-armed group bent on stealing the new Metal Gear for their
own, nefarious purposes.
