Zanzibar Island referrs to An eastern region of the continent of Africa on Earth comprising Zanzibar Island and several adjacent islands off the northeast coast of Tanzania.
Once a tropical paradise, Zanzibar is now a small abandoned township off the coast of Africa about 20 clicks north of New Mombasa, which was the Covenant's main incursion point in their attack on Earth in 2552. It housed one of the 49 large power generators that powered various facilities around that area before it was decomissioned. It is one of the many various battlegrounds of the Covenant's invasion. Survivors of the initial assault call it "Hell on Earth".
Wind Power Station 7, also known as Camp Froman, is located on the island of Zanzibar. It has been all but decommissioned. It serves as a mute reminder of the late 25th century's attempt at re-nationalization.
This area is the location of the multiplayer level Zanzibar.
