Solid Snake first locates hostage
Donald Anderson, the DARPA chief. After he informs Snake of Metal Gear REX's deactivation procedure, he mysteriously dies of what appears to be a
heart attack. Following a brief encounter with Meryl Silverburgh, who aids their escape from the base prison, Snake continues on to find the other hostage, ArmsTech president
Kenneth Baker. He is used as bait by Revolver Ocelot, and Snake is challenged to a gunfight, interrupted by the arrival of a mysterious cyborg ninja who severs Ocelot's arm before escaping. Snake is again briefed on the Metal Gear project by Baker; much like the DARPA Chief, he dies of a sudden heart attack just before revealing key information.
Snake then contacts Meryl via Codec, and agrees to meet her in the base's warhead disposal area on the condition he contact Metal Gear's designer, Hal "Otacon" Emmerich. While searching for him, he encounters the giant Vulcan Raven in an
M1 Abrams tank, which he swiftly disables, and locates Otacon in his lab. The cyborg ninja Snake previously encountered reappears, and after a hand-to-hand battle reveals himself to be Solid Snake's former ally
Gray Fox, who Snake believed he had killed years earlier. Before they can settle their score, the ninja vanishes again. Otacon, while safe, is unaware that Metal Gear is to be used as a nuclear delivery system, and breaks down when Snake informs him that he is continuing his family's close involvement with the US nuclear program. He agrees to aid Snake remotely, using special
camouflage to procure information and supplies while remaining unseen. Snake then meets Meryl, and they discuss their differing roles as soldiers. Meryl having joined the military to feel closer to her father, an Army officer killed in action. Ultimately he allows her to accompany him on his mission. Their reunion is brief, and when she is being telepathically coerced by Psycho Mantis to attack Snake,
[26] Snake defeats him by plugging the PlayStation controller into a different port, preventing Psycho Mantis from reading his mind. After they defeated Psycho Mantis, Sniper Wolf ambushes them, wounding and capturing Meryl and eventually Snake in a sniper duel.
While imprisoned, Liquid confirms Snake's suspicion that they are twin brothers.
[27] He hands Snake over to Ocelot, who tortures him,
[28] but Snake quickly escapes, and after being chased to the top of the base's Communications Tower, he encounters Liquid again, in a
Hind-D attack helicopter. Despite being outgunned, Snake shoots it down,
[29] and upon descending the tower is yet again ambushed by Sniper Wolf, and kills her following a second duel. Otacon, enamored with her, is overwhelmed with grief, but continues to assist Snake.
Snake descends into the bowels of the Shadow Moses facility, first cutting through the base forge then down into the warehouses below. Here he encounters Raven again, this time face-to-face, and kills him. Before he dies, Raven reveals that the DARPA Chief who Snake encountered was actually FOXHOUND member Decoy Octopus in disguise.
[30] Shortly after, Master Miller calls and reveals that Dr. Naomi Hunter, a support agent, had given Solid Snake the genetically engineered virus "FoxDie" during his mission preparations, and is sending coded messages into the facility- Campbell swiftly orders her arrest. The virus, designed to kill people with particular genetic markers via cardiac arrest,
[31][32] was responsible for the deaths of Octopus and the Armstech president.
[33] Naomi, struck by guilt, contacts Snake in secret and confesses that she joined the mission to sabotage it, as she is the adoptive sister of the now barely human Gray Fox. However, upon learning of Snake's own tragic past through the current mission, she no longer has the heart to kill him directly, having reprogrammed the virus.
[34]
Infiltrating Metal Gear's hangar and following the supposed procedure to disarm the warhead, Snake unknowingly activates Metal Gear REX,
[35] after which Master Miller reveals himself to be Liquid in disguise. He informs Snake that his entire mission was manipulated by the renegades to allow the launch of the nuclear weapon.
[36] As a parting gift as he boards REX, Liquid explains that they are the product of the 1972
Les Enfants Terribles project, a government sponsored effort to
clone legendary mercenary Big Boss. However, part of the process requires that their genes be altered, Solid receiving all of Big Boss' dominant genes, and Liquid receiving all the recessive genes.
[37][38]
Drawn into battle with Metal Gear REX, Snake manages to disable the machine's sensors with the aid of Otacon, and Gray Fox (who admits to being "Deepthroat") manages to destroy its radome, but is wounded and crushed by its foot. REX is destroyed, but Liquid survives, challenging Snake to a final fist-fight atop Metal Gear, where Snake succeeds and is reunited with Meryl- possibly for the final time, depending on the player's actions (see below). After a protracted jeep-chase with the seemingly unkillable Liquid, Snake finally escapes the facility, and his brother collapses, killed by FoxDie.
[39] Colonel Campbell, briefly ousted from command of the mission, calls off a nuclear airstrike intended to obliterate the evidence of the day's events, and officially declares Snake killed in action to prevent the US Government returning for him in the future. In the immediate aftermath, the player finds out Snake is actually genetically inferior to Liquid
[40] and has an indeterminate amount of time left before FoxDie kills him.
[41]
Depending on the player's actions during the game, there are two possible endings: in one ending, Ocelot kills Meryl and Snake escapes with Otacon, while in the other ending, she survives and escapes with Snake. Meryl's survival is recorded as canon by
In the Darkness of Shadow Moses, a story featured in
Metal Gear Solid 2: Sons of Liberty. A telephone conversation following the credits reveals Ocelot to be a double agent for the
President of the United States, the third Snake
Solidus. Ocelot's intention was to gain Baker's disk containing Metal Gear's specifications and deliver it to the President.
