From Halopedia, the Halo wiki
Mombasa is a major Earth city in the Kenyan portion of the East African Protectorate. The heart of the city was the prosperous New Mombasa on Mombasa Island. The nearby mainland was the site of Old Mombasa, a comparatively run-down district.
Mombasa underwent dramatic change with the arrival of the interstellar era. In response to increasing demand for cheap orbital access, due to its economic stability and prominent location, Mombasa was chosen to be Earth's first Space Elevator city. The government began construction on one of the wonders of the age: a space elevator (Mombasa's proximity to the equator made it an ideal location) in 2302. This structure served to lift heavy cargo into geosynchronous orbit without expensive booster rockets filled with fuel.
Over the next eleven years the city experienced explosive growth, but nothing compared to what followed. The city grew out as well as up, its urban sprawl unequaled throughout the continent.
Mombasa would change dramatically within the centuries that followed. By 2430, New Mombasa had absorbed the entire island and many of the surrounding towns, which became overrun by residents of Mombasa. The switch of name was never official, and though many of the neighborhoods within direct line of sight to the Mombasa Tether still distributed newspapers and Chatter directories under their previous names, all municipalities within a 74 km radius of the island became referred to as "Old Mombasa."
On October 20, 2552, a small group of Covenant capital ships arrived at Earth. Uninformed of the Human presence on Earth, Regret was outnumbered and outgunned against the UNSC Home Fleet. During the orbital battle, the Prophet of Regret's Flagship broke through Earth's defenses and descended to the atmosphere, and anchored itself above New Mombasa. The Covenant started deploying their ground forces to the city, in search of a Forerunner relic, the Ark Portal, buried under the city.
However, due to a strong UNSC counterattack and the inferior numbers of the Covenant, Regret ordered all of his forces to be evacuated back aboard the Carrier. After this, the ship jumped into slipspace just above the city, releasing a shock wave and pulling multiple city blocks from the mainland with it. This event became known as the "New Mombasa Slipspace Event." In the hours after Regret's retreat, a larger Covenant fleet arrived at Earth. After sending in ground forces and crushing the remaining UNSC resistance in the city, they glassed the area in order to uncover the Portal. In the final days of the Battle in Africa, only smoldering ruins of Mombasa remained.
Following the end of the war, the Unified Earth Government began Project Rebirth to rehabilitate war torn areas on Earth. At some point, the Project started work in Mombasa. The old city hall thoroughfare for Mombasa was to be transformed into the UNSC Memorial Park.
Mombasa Island, where the metropolis of New Mombasa lies, is separated from the mainland by two creeks: Tudor Creek to the north and Kilindini Harbour to the south. Northwest of the island and between the inlets, there used to be a large peninsula, connected to the Mombasa island by the Makupa Causeway.[note 1]
The City Center spans much of the Southeast portion of the island, being divided in multiple walled sectors.[note 2]
While the majority of New Mombasa has been divided to numbered sectors, some districts such as Mbaraki, Kizingo or Kikowani still retain their original names. The original names are often seen in the names of streets or train stations, for example. Some of the districts' names have changed, albeit slightly; areas originally referred to as Tangana and Liwatoni are now referred to as Tanaga and Liwitoni, respectively. The locations of some districts have changed as well. This is the case with most of the districts on the southern side of the island, where the sea has claimed large areas of land.
Leadership and management
Numerous departments existed in Mombasa including; the Department of Health and Human Services, the Department of Housing, the Department of Public Safety, the Department of Recreation, the Department of Streets and Sanitation, and the Department of Utilities and Transportation. The city also maintained a public works department.
The economy of Mombasa is vast, ranging from interstellar/multi-planetary corporations of varying sectors to smaller local Earth businesses.
Corporations in city
The architecture of the city is different depending on the location. Old Mombasa's architecture was an odd hodgepodge of old and new: 16th-century Muslim arcades, aging 21st-century office buildings, looming 26th-century power couplings, old concrete homes secured with computerized locks. Clotheslines strung next to power lines, and mechanical gates set into ancient brick walls. In some areas, newer skyscrapers had found their home.
The culture also seems displaced between the different parts of the city; while New Mombasa was populated with industrial workers and ambitious cosmopolitans, Old Mombasa was considered to be more of an old rundown slum that deteriorates by the day. The denizens of the old city were largely isolated from the residents of New Mombasa; even their dialect was completely different from the standard language.
Mombasa and surrounding areas appear numerous times in Halo games.
Mombasa is one of the locations visited in Halo 2's campaign. It is featured in two campaign levels; Outskirts which takes place in Old Mombasa and Metropolis which mostly takes place in the industrial zone of New Mombasa. Several multiplayer maps take place in the Mombasa area as well. Terminal, Ivory Tower, Tombstone, District, and Turf are all in various locations and various points in the city's history.
Mombasa is not a playable space in Halo 3's campaign. However its ruins can be seen in Tsavo Highway and The Storm across the other side of The Portal. The Mombasa area, specifically the Mombasa Quays, is playable in the map Longshore from the Mythic II Map Pack.
Halo 3: ODST
Save for the very final cutscene, every level of Halo 3: ODST's campaign and every map in Firefight take place in Mombasa. Most prominently, the levels and maps are set in the New Mombasa city center. Mombasa Streets allow players to explore several sectors of the city center. The placement of some landmarks, like the Orbital elevator is different than what is seen in Halo 2.
A mainland portion of Mombasa is playable in the map Breakneck as part of the Anniversary Map Pack. Numerous landmarks can be seen outside the boundaries of the playable space. This version appears to be very similar to ODST's design of the city, though some elements of the city geography do not line up with any known depiction of Mombasa.
Halo: Spartan Strike
The city is seen in the first operation of Spartan Strike; Operation A: Orphic Spear, and in the first half of the last operation, Operation E: Brother's Keeper. All the missions on the first operation and first half of the last one take place in New Mombasa and takes elements from Halo 2 and ODST.
The Mombasa area was first seen during the Halo 2 E3 demo where it was significantly different than designs of the city seen in released media. In the demo, the city was a large tree like structure stretching into the sky. This structure was removed for the final game where the designers wanted the city to feel more real. They then based it more on the actual city using photographs to help imagine what it would look like 500 years into the future.
