Halo 3: ODST Original Soundtrack

"Overall I think this score is a bit more intimate and personal. We're telling a human story, not a cyborg story. This isn't a space opera but a story that takes place on Earth in one city. Although the player gets to inhabit the shoes of several characters, they still primarily should feel like one person discovering the mystery that lies behind the ruins of New Mombasa."

- Martin O'Donnell to Music 4 Games

Trivia

 * The movement "Orbital Drop Shock Trooper" from the Finale has a runtime of 3:43, a reference to 7 and possibly the eponymous Monitor 343 Guilty Spark. Additionally "Prepare to Drop," named after the game's tagline, has a runtime of 1:17, a reference to Master Chief.
 * Marty O'Donnell was going for more of a jazz perspective. Throughout the soundtrack there are several songs that contain solo saxaphone sections to add to the created atmosphere. In the tracks "Skyline" and "Traffic Jam" however, an electric guitar along with heavier sounding percussion are used to create cinematic moments in the game.
 * The soundtrack won several awards; the Best Original Score at the 2009 Spike Video Game Awards and Best Original Score and Sounds in the Czech Gaming Awards "Invaze 2009".
 * Most of the tracks that play during Mombasa Streets have a film noire flare, due to the jazz perspective used in the soundtrack. This seems fitting, since most film noire movies are about detectives, and The Rookie is, in a sense, a detective.
