After putting an end to Big Boss and his army at Outer Heaven, Solid Snake must infiltrate Zanzibar (Zanzibarland) in Central Asia. Snake is ordered to retrieve a captured scientist that holds the key to the world's current energy crisis. Metal Gear 2: Solid Snake greatly improves the stealth gameplay from the original and the story is introduced with more detail than the first game.
Snake meets up with a few familiar characters from the first game along with some new faces. Metal Gear 2 marks the first appearance of the new commander of FOXHOUND, Roy Campbell. McDonnell Miller also serves as another contact for Solid Snake. Metal Gear 2 was originally released for the MSX in Japan and has only been released in North America in Metal Gear Solid 3: Subsistence along with the original Metal Gear.
This game is also known as Metaru Gia Tsū Soriddo Sunēku in Japan.
