Two years after Shadow Moses, Otacon received an anonymous tip from someone calling him or herself "E.E." (the initials of Otacon's younger stepsister) that a new Metal Gear, codenamed Metal Gear RAY, was being developed by the U.S. Marine Corps., and was being sent via a Marine vessel disguised as an Oil Tanker.
The tanker was, however, quickly taken over by a group of Russians led by Colonel Sergei Gurlukovich. Snake met Gurlukovich's daughter Olga on board the tanker, but proceeded to defeat her in a gunfight; however, she promptly disappeared afterwards. Snake quickly made his way into the tanker's interior and, as per his mission orders, secured photographic evidence of the new Metal Gear. Neither he nor Otacon could have predicted the reappearance of Revolver Ocelot on the tanker. Ocelot proceeded to sink the vessel and steal RAY. Thanks to the photographs taken by a U.S. Army CYPHER, the Patriots framed Solid Snake and Philanthropy in a smear campaign for the deed, simultaneously exposing them to the public and destroying their reputation.
