The complete soundtrack for the Halo Reach Campaign, exactly the way it's heard while playing.
All music composed by Martin O'Donnell & Michael Salvatori.
All tracks mixed and arranged by me.

Track 05: Nightfall
1. Recon (includes opening cinematic) 0:00
2. Hostiles 3:56
3. Personnel Issues 6:35
4. Keeping What I Steal 9:01
5. Howling Dark 11:59
6. Riverbed 13:45
7. Lone Wolf Part 1 16:09
8. Dark Zone 17:44
9. Lone Wolf Part 2 18:22
10. At Dawn 20:23
11. Closing cinematic 21:05

Notes:

At 2:15, the voice in the background is singing part of the OST track “Ashes”.

In my opinion, Hostiles and Lone Wolf are the two most glaring omissions from the OST.
