Soundtrack
David Bowie, who had some input on the storyline and game's design, makes two cameo appearances within the game, although not as himself; first as Boz, a game character who's a revolutionary wanted by authorities, and secondly as the nameless lead-singer of the fictional musical group, "The Dreamers", who perform illegal concerts in Omikron. In addition, select tracks from his (then) upcoming 'hours...' album were written specifically for the game then rewritten for the actual album release. For instance, the intro song New Angels of Promise changed the chorus lyric Omikron to Suspicious Minds.
The game's soundtrack is a main feature as well, featuring songs by Bowie and Reeves Gabrels (most of which appeared on 'hours...' or as B-sides on the associated single for the song "Thursday's Child") in addition to the primary composition work by Xavier Despas. Most of Bowie's songs are then available (in-game only) for later listening either if the player opts to "buy" the recordings or simply walk into an apartment that already has some of the music laid out in plain view or in hidden compartments. Bowie's wife Iman also makes a cameo as one of the numerous Omikronian citizens the player can "reincarnate" into.
