A different version, one that is more true to the original Halo Theme is also featured during the Warthog escape in the level Halo. The song plays at the beginning of The Covenant, and during the Scarab battle. Also, a large part of this song is used as part of the Truth and Reconciliation Suite. Furthermore, this song also seems to be a remake of Unyielding from Halo 2. The end is a soft string melody that fades to a close. It then switches to the Halo 3 version of the Halo Theme. It starts with a piano playing the theme from This is the Hour. It is the third movement of the Covenant Suite. It is heard on the level The Covenant at the start and when you face the two Scarabs.
One Final Effort is a song included in the Halo 3: Original Soundtrack.
