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 get's 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"
