To Kill a Demon
From Halopedia, the Halo wiki
To Kill a Demon is a song included in the Halo 3: Original Soundtrack. It plays during the level Tsavo Highway, and includes the tracks To Kill a Demon, Ancient Dust, Punch Through, and Underestimated.
The beginning of the song has the same melody as the middle part of "This is our Land", and is heard during the battle with the Phantoms in the canyon after the broken bridge.
It contains a remake of Rock Anthem for Saving the World from the original Halo, played shortly after the "This is Our Land" section, a remake of Under Cover of Night, and a remake of the Halo Theme, with the rhythm of Farthest Outpost, at the end of the track, heard in-game during the approach to the gates of Voi.
It runs for 3:45.
