It also plays in the level "The Pillar of Autumn", after you encounter the first group of Covenant to board the Autumn through the use of the lifeboat airlocks.

The piece has been remade and plays in the Halo 3 level The Ark (Level). It can be found in the Halo 3 Original Soundtrack in the second half of the song Farthest Outpost
