What is the name of the Alaskan island where the original Metal Gear Solid takes place?

The original Metal Gear Solid takes place on Shadow Moses Island.

Shadow Moses is a fictional island in Alaska that contains a nuclear weapons disposal facility. In 2005, the special forces unit FOXHOUND seizes the facility and threatens to launch a nuclear strike using Metal Gear REX. Solid Snake is sent to infiltrate the island and resolve the crisis.

The island is more than a backdrop: its snowy terrain, industrial buildings, underground corridors, and communications towers shape the game’s stealth challenges. Players move between outdoor and indoor areas while gathering keycards, rescuing hostages, and confronting FOXHOUND members. Shadow Moses is often remembered as one of the series’ most important locations, and it is revisited in altered form in later Metal Gear stories and references.
