Devils... Monsters...

Devils... Monsters... is a song included in the Halo: Original Soundtrack. It runs for 1:32.

It repeats several notes many times, with carefully placed variations designed to surprise the listener. Parts of this song are used in later games in the Halo series, most notably for the Halo 3 boss fight with 343 Guilty Spark in the song Halo Reborn.

The name of the song is a reference to The Flood, as it plays in the Library and for many of their other appearances. You can listen to it here: []
