Metal Gear Solid GBC
Metal Gear Solid is a non-cononical sequel, released for the GameBoy Color. The game is known in Japan as Metal Gear: Ghost Babel, and the name is often used in the West to avoid confusion with the PSX game.
The game focuses on Solid Snake's return to Outer Heaven, where a new Metal Gear, code-named GANDER, is being housed. Snake's mission is to infiltrate the fortress nation again and destroy Black Chamber, an organisation attempting to steal the weapon.
