Epilogue is the eleventh track (Disc 2 Track 4) included in Halo: Reach Original Soundtrack, and plays in the Halo: Reach campaign level Lone Wolf. It is composed of Spartans Never Die (0:00-0:55), Omega (0:55-2:08), and Hymn for Reach (2:08-4:30).
Spartans Never Die
Spartans Never Die (0:55) is a piano solo of the first theme from the later track Ghosts and Glass. The piece plays in the opening cinematic, with the final notes leading into the campaign level's opening gameplay moments.
Omega (1:13) features an eerie ambience by low strings, accompanied by male choir singing a dissonant melody. The piece plays when Noble Six’s helmet takes permanent damage during gameplay, and continues into the ending cinematic, up until the Spartan’s helmet is shown discarded in the dusty ground.
Hymn for Reach
Hymn for Reach (2:12) opens with high strings playing a sad, but hopeful, melody. The choir joins as the melody repeats for the first time. When the melody repeats for a second time, the instruments and choir enter a higher register at the end. High strings then take over for a serene and delicate bridge, playing in solo until the other instruments return for an uplifting finish. The piece plays in the final cinematic, when Catherine Halsey recites a eulogy to Noble Six, and it is revealed that Reach has returned to a habitable state in 2589. A shortened strings-only version of the piece was featured as Wing and a Prayer (from the earlier track New Alexandria), and the melody was used as a remix for the later track We Remember.
