Story
The story takes place between Metal Gear Solid and Metal Gear Solid 2: Sons of Liberty, after Revolver Ocelot has leaked technical information on Metal Gear REX to the world. As a counter-measure, Solid Snake and Otacon form Philanthropy, an anti-Metal Gear organization whose goal is the complete eradication of all Metal Gears. Otacon quickly receives his first lead on development of a new Metal Gear. AI programmer Dr. Victoria Reed has agreed to reveal new details on the Metal Gear in exchange for assistance in her escape.

Midway through the mission however, it turns out Victoria Reed means VR. Snake finds out the Otacon he is talking to is part of a giant VR simulation. Otacon from the outside world then breaks in and helps guide Snake out of the VR simulation. Snake fights "The Commander" on top of a VR Metal Gear Rex. After defeating him, Snake wakes up to unnamed voices speaking. They say that while Snake did prove useful, he failed to provide them with the battle data they needed for the Project, and they instruct someone to erase all memories of the simulation and dump him back where they kidnapped him. One unnamed voice then says that they already have the second test subject lined up. One of the voices then says, "...Let's see if Jack can do better."
