Metal Gear Solid: The Twin Snakes

Metal Gear Solid: The Twin Snakes is an action-adventure stealth video game co-developed by Silicon Knights and Konami Computer Entertainment Japan for the Nintendo GameCube video game console in March 2004. The game is a remake of Metal Gear Solid, originally developed by Konami Computer Entertainment Japan for the PlayStation in 1998.

The Twin Snakes features graphical improvements over the original, new cutscenes written and directed by Ryuhei Kitamura, and gameplay functions originally introduced in the sequel Metal Gear Solid 2: Sons of Liberty. The game includes a revised translation with re-recorded voice acting using almost all of the original English voice cast. The game was met with positive reception.

Plot
The year is 2005, six years after the downfall of Zanzibarland. A renegade genetically-enhanced special forces unit, FOXHOUND, has seized a remote island in Alaska's Fox Archipelago codenamed "Shadow Moses", the site of a nuclear weapons disposal facility. FOXHOUND threatens to use the nuclear-capable mecha, Metal Gear REX, against the US government if they do not receive the remains of Big Boss and the ransom of $1 billion within 24 hours. Solid Snake is forced out of retirement by Colonel Roy Campbell to infiltrate the island and neutralize the threat.

Snake enters the facility via an air vent and locates the first hostage, DARPA Chief Donald Anderson. Anderson reveals that Metal Gear REX can be deactivated with a secret detonation override code, but dies of a heart attack. Colonel Campbell's niece Meryl Silverburgh, held hostage in a neighboring cell,  helps Snake escape. Snake locates another hostage, ArmsTech president Kenneth Baker, but is confronted by FOXHOUND member Revolver Ocelot. Their gunfight is interrupted by a mysterious cyborg ninja who cuts off Ocelot's right hand. Baker briefs Snake on the Metal Gear project and advises him to contact Meryl, whom he gave a PAL card that might prevent the launch, but he too dies of a sudden heart attack.

Over Codec, Meryl agrees to meet in the warhead disposal area on the condition that Snake contacts Metal Gear's designer, Dr. Hal "Otacon" Emmerich. En route, Snake receives an anonymous codec call warning him of a tank ambush. Snake fends off the attack from Vulcan Raven and proceeds to the rendezvous, where he locates Otacon. The ninja reappears, and Snake realizes it is his former ally Gray Fox, believed dead. Otacon agrees to aid Snake remotely using special camouflage to procure information and supplies.

Snake meets Meryl and receives the PAL card. As they head for the underground base, Meryl is possessed by psychic Psycho Mantis and pulls her gun on Snake. He disarms her and defeats Mantis, who informs Snake that he has "a large place" in her heart. After they reach the underground passageway, Sniper Wolf ambushes them, wounds Meryl, and captures Snake. Liquid confirms Snake's suspicion that they are twin brothers. After being tortured by Ocelot, Snake is confused to discover Anderson's body in his cell, seemingly dead for days. He escapes, makes his way up the communications tower, and fends off a Hind D helicopter attack from Liquid. As he emerges onto a snowfield, he is confronted again by Sniper Wolf. He kills her, devastating Otacon, who was infatuated with her.

Snake continues to REX's hangar and is ambushed again by Raven. After Snake defeats him, Raven tells Snake that "Anderson" was, in fact, FOXHOUND disguise artist Decoy Octopus. Infiltrating Metal Gear's hangar, Snake overhears Liquid and Ocelot preparing the REX launch sequence and uses the PAL card, but this unexpectedly activates REX. Liquid reveals that he has been impersonating Snake's advisor Master Miller and that FOXHOUND has used Snake to facilitate REX's launch. He and Snake are the product of the Les Enfants Terribles project, a 1970s government program to clone Big Boss. He also reveals to Snake the government's true reason for sending him: Snake is unknowingly carrying a weaponized "FoxDie" virus that causes cardiac arrest in FOXHOUND members on contact, allowing the government to retrieve REX undamaged.

As Liquid, in REX, battles Snake, Gray Fox appears, destroys REX's radome, and is killed. Snake destroys REX and defeats Liquid, then escapes with Meryl or Otacon via a tunnel, pursued by Liquid in a Jeep. After their vehicles crash, Liquid pulls a gun on Snake but dies from FoxDie. Colonel Campbell, briefly ousted from command, calls off a nuclear strike to destroy evidence of the operation and has Snake registered as killed in action to stop the US government searching for him. Naomi Hunter, who injected Snake with the FoxDie virus, tells him that he has an indeterminate amount of time before it kills him. Ocelot calls the US President; he was a double agent whose mission was to steal Baker's disk of Metal Gear specifications.
