Lone Wolf (2:23) fades in with low strings and muted percussion.
The tribal percussion has reprises in Belly of the Beast (from the later track Long Night of Solace) and Special Delivery (from the later track The Pillar of Autumn). The piece plays in the first campaign level Noble Actual and in the The Battle Begins trailer. The piece ends with strings and vocals playing the melody in repeat before fading out. The melody repeats in variation before percussion instrument changes but plays the same rhythm.
After another drumroll and a brief bass section, a tribal percussion enters in repeat, accompanied by strings and vocals invoking the Halo Theme. The Battle Begins (3:10) open with a drumroll and a male choir.
