Under Cover of Night

Under Cover of Night is a song included in the Halo: Original Soundtrack.

It runs for a total time of 3:43.

It was remade as Halo Reborn in the Halo 3 Soundtrack

It is interesting to note the runtime of this piece: 3:43, like 343 Guilty Spark.

It is heard in almost every level of Halo 1, starting with Halo. The song is played near the underground Forerunner base on Halo, near the beginning of the level Truth and Reconciliation after the first sniping part, the part of the Silent Cartographer where the player comes to the Cartographer building for the second time, the Assault on the Control Room when wandering through the innards of Halo, the end of 343 Guilty Spark, certain points in The Library, near the end of the level Two Betrayals, at the start of the Final Run chapter, and in Keyes, while outside the ship.

It is also an Easter Egg in Halo 3 on the map High Ground. It is sometimes heard playing from the radio at the large base.
