Voi

Voi is a current-day market city in Kenya, Africa, and is also set to be part of the plot of Halo 3.

Location
It is nearby Mombasa, Kenya, and serves as the crossroads for railway lines between three Kenyan cities, including Mombasa and Nairobi.

Topography
Voi is described in its concept art to be a "worker town", and is filled with mechanical factories and shoreline buildings. It also houses an enigmatic system of "tethers", arcing semicircles of thick metal that belt into the air. These tethers are also associated with The Road, and can be seen or are part of the outskirts where The Road takes place.

Halo 3
Two successive Halo 3 campaign levels - Assault and Last Stand, are set to take place in Voi. This was authenticated when hackers were able to hack the source code of the Halo 3 Beta.

The Road, the third campaign level and the one immediately preceding Assault, is widely believed to be the fighting of the player along one of the roads or railway tracks between Voi and Mombasa. The second campaign level, Holdout, is believed to take place in the outskirts of Mombasa.

Assault is believed to be the character assaulting Covenant forces entrenched in Voi. Last Stand, according to the hacking of the Halo 3 Beta code, is associated with the Flood, and it is believed that after dispatching the Covenant forces of Voi, the character must defend Voi against the Flood.

Trivia

 * In Volume Two of the Halo 2 Official Soundtrack, it featured a song titled "Road to Voi".
