What Once Was Lost is a soundtrack piece included in the Halo: Original Soundtrack. It primarily uses swamp noises and animal cries as undertones to add to the suspense.


It plays during the start of the level 343 Guilty Spark and during a portion of Keyes when the player goes down into the big room that was encountered after entering the ship on Truth and Reconciliation.
