117

This article is about the track on the Halo 4: Original Soundtrack. For the main protagonist of the Halo series, see John-117. For the Halo 3 campaign level, see Sierra 117.

117 is the twelfth track of the Halo 4: Original Soundtrack. It serves as one of the main themes of Halo 4, as evident from many other tracks that draw inspiration from it, including Wreckage, Mantis, and Sacrifice. At 6 minutes and 10 seconds in, structures from Halo 3's One Final Effort are invoked.

Its motif is reused in the Halo: The Fall of Reach Animated Series soundtrack Choose Our Weapons and in the Halo 5: Guardians soundtracks Rock and Ice, The Trials, Blue Team, Crypt, and Scavengers.
