The Office of Naval Intelligence (music)

The Office of Naval Intelligence is the ninth track from the first CD included in the Halo 3: ODST Original Soundtrack. It contains the tracks A Heavy Toil, Strong Medicine, Uphill Both Ways, Access Denied, Infestation, and Clear the Air. It is the music for the ONI Alpha Site.

The song starts out much like Roll Call/Duty Bound/Price Paid from the Halo 3 Original Soundtrack, but more urgent, as if enemies are nearby. Around 1:10, the song changes to slow strings. At 2:33, action reenters the song again, in an original combination of drums, cymbals, and bass. At 4:12 we are treated to a section of the song that sounds unnervingly like the beginning of Gravemind from the Halo 3 soundtrack. This goes on until 6:17, where we only hear an eerie synthesized rattling noise over a looping, fluctuating "whorl" sound. At 7:17, a much lighter tribal beat takes over; this continues until the end of the song, where it fades out.
