What Once was Lost is a soundtrack piece included in the Halo: Original Soundtrack.
Appearances
It plays during the outside portion of the level Template:Levelname, and also during a portion of Template:Levelname. It adds to the tension the player feels before and after discovering the Flood. It primarily uses swamp noises such as animal cries, with undertones to add to the suspense. The soundtrack itself creates much of tension to suit the dark mood of the level.
