Under Cover of Night

Under Cover of Night is the tenth piece included in the Halo: Original Soundtrack.

Overview
The song consists of a slow synth melody with a more complicated bass line interweaved. There are no drums in the song until 1:45, before which the bass provides the rythm. After the drum beat is added, occasional chants can be heard.

Appearances
The track can be heard:
 * In the level The Truth and Reconciliation, when John-117 and Fire Team Charlie make their way around the ridge.
 * In the level Two Betrayals, when John-117 arrives at the final canyon.
 * In its original form in Halo Legends short film Homecoming, when Daisy-023 discovers her flash-clone.

Remastered versions
It is remastered into the following:
 * In Amber Clad in the Halo 2: Original Soundtrack as an inspired piece.
 * Wage of Delta Halo Suite in the Halo 2: Original Soundtrack as a background melody, which was then remixed into Delta Halo Suite in the Halo Legends: Original Soundtrack.
 * Beginning section of Follow our Brothers in the Halo 3: Original Soundtrack.
 * Beginning section of Halo Reborn in the Halo 3: Original Soundtrack.
 * End of Kill a Demon in the Halo 3: Original Soundtrack; at the ending of the Tsavo Highway level.
 * Cloaked in Blackness in the Halo: Combat Evolved Anniversary Original Soundtrack.

Trivia
The soundtrack appeared as an easter egg in Halo 3 on the multiplayer map High Ground. It is sometimes heard playing from the radio at the large base.

Under Cover of Night and its versions have almost always appeared in relation to a Keyes. The Halo Combat Evolved appearances appear near a mention or focus of Captain Keyes. Every post-Combat Evolved appearance directly features Miranda, or invokes her (In Amber Clad). In Homecoming, the music plays in a scene where Miranda's mother appears.
