Voi

Voi is a current-day market city in Kenya, Africa.

Location
Voi was near New Mombasa, Kenya, and served as the crossroads for railway lines between three Kenyan cities, including New Mombasa and Nairobi before being destroyed by Flood and then glassed by the Covenant Separatists.

Topography
Voi is described in its concept art to be a "worker town", and it is filled with mechanical factories and shoreline buildings. Nearby are the remains of the New Mombasa Orbital Elevator from Halo 2, which are scattered across the level Tsavo Highway (Level). Voi in the mid 26th century is situated around a man-made lake. As a result of the global warming period of the 21st century, the snow melt that supplied Voi with a water supply died off, creating a major water shortage. It was decided to construct a man-made lake to store water from the remaining mountain runoff, this lake was built at what was then the southeastern edge of Voi. By now Voi has grown to such a size that it almost totally surrounds it and a ferry service was constructed to carry cargo and people across the lake. One of the ferries is encountered stranded on a beach during the level The Storm. Along with that, the Voi River still runs through, providing easy transport up and down the river for the industry.

Battle of Voi
The Master Chief, arrives in Voi via Tsavo Highway and joins up with the Arbiter and a large group of Marines. The Battle of Voi begins with the UNSC attacking entrenched Covenant Loyalist forces. Together they destroy many Anti-Air Wraiths, a Scarab, and a Covenant anti-air gun. With the anti-air forces destroyed, Lord Hood's ships begin to attack the High Prophet of Truth's Forerunner Dreadnought, until Truth activates the Portal to the Ark and escapes. After this, a damaged Covenant Cruiser crashes in at the western edge of the city. This ship is full of Flood, and the Master Chief and the Arbiter begin to fight this new threat. They start to move to the downed Cruiser, hoping to destroy it and contain the Flood. As they near the Cruiser, a Covenant Separatist ship arrives, led by Shipmaster Rtas 'Vadum. The ship, the Shadow of Intent, deploys Elite ground forces to assist the Humans. The Humans learn that the Separatists are looking for Cortana, who is supposedly aboard the Flood Cruiser. Separating from the Arbiter, the Chief goes aboard the Cruiser. What he finds is not Cortana, but a damaged message left by her. As he is inspecting it, 343 Guilty Spark arrives to repair Cortana. All Human and Elite forces retreat to the Shadow of Intent as 'Vadum glasses Voi, therefore destroying all Flood in the vicinity and preventing the parasite from spreading any further.

Halo 3
Voi is a key location in Halo 3.

Three successive Halo 3 campaign levels - Tsavo Highway, The Storm and Floodgate, take place in or around Voi. The multiplayer maps Foundry and Ghost Town are also set in Voi. More specifically:


 * Tsavo Highway, the third campaign level, takes place along the Tsavo highway, leading to Voi.
 * The Storm deals mainly with the character assaulting Covenant forces entrenched in Voi.
 * Floodgate deals with clearing the Flood from the city, although the city is eventually glassed by Covenant Separatists.

Trivia

 * The town of Voi was actually first seen in the Halo 3 Announcement Trailer more recently to the launch of the game, the only part seen was the billboard on fire (Floodgate) and the Master Chief emerging from the destroyed elevator out of Crow's Nest which wasn't near Voi at all.
 * There is a SAM launcher similar to the one on High Ground pointed directly at the AA battery.
 * The last movement of the Halo 2 Soundtrack is called "The Road to Voi".
