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, Sacrifice and Majestic. 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.
