To Kill a Demon

200px|right To Kill a Demon is a song included in the Halo 3: Original Soundtrack. It plays during the level Tsavo Highway.

Note: The name of the song is most likely derived from the dream of each Covenant soldier to "kill the Demon."

The beginning of the song has the same melody as a part in "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. It runs for 3:42.
