Well, the first part of the game, the "Tanker" chapter chronicles the events after Solid Snake, Otacon, and their organization, Philanthropy, obtain classified information that a new prototype of Metal Gear is being transported under cover of an oil tanker to an unknown destination. Armed, Snake infiltrates the tanker to keep it from falling into the wrong hands, but something goes wrong. Russian terrorists board the tanker while all of the marines are in the hold. Snake sneaks to the hold. He watches as the Commander of the Terrorists(Gurlukovich) tries to steal Metal Gear Ray but Revolver Ocelot(with Liquid Snake's arm) double-crosses him and steals is for "The Patriots." The tanker sinks, ocelot gets away, Snake is presumed dead.
