Zanzibar Land is a nation-state in the Metal Gear universe led by Big Boss, established as a continuation of his original soldier nation, Outer Heaven. They are the antagonists of Metal Gear 2: Solid Snake.
Zanzibar Land emerged from a war for independence against the Commonwealth of Independent States. Zanzibar emerged victorious, with help from mercenaries. This prompted the war to become known as the "Mercenary War". Big Boss wanted Zanzibar Land to be the culmination of the Outer Heaven movement, and thus made it a home for all soldiers, even former enemies. War orphans were also taken in to become "fine soldiers" themselves.
Zanzibar Land soon began fortifying its military arsenal, raiding nuclear disposal sites across the world to obtain nuclear weapons that were still intact. The nation-state soon began a conquest of its neighboring countries at will, marking its growth into a world superpower. With Metal Gear D as created by Dr Madnar, and an army comprised of mercenaries, Zanzibar Land became one of the world's only nuclear powers at a time of disarmament and peace.
Operation Intrude F014
In December 199, Zanzibar Land kidnapped the biologist Dr. Marv, who had developed OILIX, a much needed new fuel, and planned to hold the world hostage by controlling the supply of oil, along with the threat of nuclear war, in an era known as the Zanzibar Land Disturbance. This prompted Solid Snake to be sent in to rescue him. Several mercenaries fought Snake, and some, such as Black Ninja and Gray Fox, knew him when they were on the same side. Gray Fox would later attempt to kill Snake with Metal Gear D, but it was destroyed. After Snake seemingly killed Big Boss, Zanzibar Land quickly collapsed.
- According to the Metal Gear Solid 4: Guns of the Patriots novelisation, Zanzibar Land was originally known as Tselinoyarsk, the setting of Metal Gear Solid 3: Snake Eater, the first chronological appearance of Big Boss.
- Many of the soldiers and mercenaries have a cult-like worship of the nation and Big Boss, with soldiers standing to attention for the full duration of it's national anthem. and many of the mercenaries, including former enemies such as Kyle Schneider speak with awe of Big Boss.
