Outer Heaven

Outer Heaven is a gigantic, impenitrable fortress 200km north of Galzburg, South Africa. It was founded by a legendary soldier, and is the location where Metal Gear TX-55 was built.

During Operation Intrude N313, rookie FOXHOUND agent Solid Snake infiltrated Outer Heaven, and succeded in rescuing the missing agent Gray Fox and destroying Metal Gear TX-55. Outer Heaven was destroyed in 1995 when it's self destruct sequence was activated after Metal Gear was destroyed.

The legendary soldier who built Outer Heaven turns out to be FOXHOUND commander Big Boss. Outer Heaven was planning to achieve military supremacy over the western nations with the development of Metal Gear TX-55 (presumably so Outer Heaven would be able to oppose the Patriots, though that's just mere speculation.

Big Boss took the ideal of Gene's Army's Heaven to create Outer Heaven with the use of Gene's funds,plans,and resources on a single film after defeating him during the rebellion in South America. It is unknown if Big Boss was bought into Gene's speech about A Calling or he was hypnotised by Gene's speech to create Outer Heaven. Sources are still unclear about the incident before Big Boss came back to America in late January 29, 1971 after defeating Metal Gear in South America.
