Mombasa Streets

Mombasa Streets is the first campaign level of Halo 3: ODST.

The level starts 6 hours after the drop, in the occupied city center of New Mombasa. It is a freely explorable open world environment.

Some time after the Rookie wakes up, exits his pod and starts to explore the city, the Superintendent will contact him via a public phone and upload a map of the city to his VISR navigation database. The map shows points of interest, such as "beacons" of the Rookie's squad mates, which trigger additional flashback missions. The Superintendent will also guide the player into the right direction using the city's plentiful digital signs and billboards.

Trivia

 * This level marks the return of the Brute Plasma Rifle.
 * This "Level" is not really a level, as it is the entire open world of the night time sessions of the campaign. Most likely, you can Free roam and search around for Covenant patrols.
 * This level is the only level in Halo 3: ODST which does not unlock an achievement upon beaten on normal or above. This is probably because of the fact that this is a free roaming level.
 * This is the first level where you play as the Rookie.
