No Stone Unturned

No Stone Unturned is the third track from the second CD included in the Halo 3: ODST Original Soundtrack. It contains the tracks Cast Aside, Nox Aeterna, and Marching On.

It is played in the Halo 3: ODST campaign level Mombasa Streets, right after the flashback level NMPD HQ. The second and third section are played randomly during Mombasa Streets. A remix of Nox Aeterna is sometimes played during Halo: Reach Firefight matches.
