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.

Reorchestrated versions
It is reorchestrated 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.
 * End of To Kill a Demon in the Halo 3: Original Soundtrack; at the ending of the Tsavo Highway level.
 * Beginning section of Follow our Brothers in the Halo 3: Original Soundtrack.
 * Beginning section of Halo Reborn in the Halo 3: Original Soundtrack.
 * 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.
