Unless You Mean to Shoot in the Halo: Combat Evolved Anniversary Original Soundtrack.Into the Breach of More Than His Share as a remix in the Halo 3: ODST Original Soundtrack.The track has been arranged into the following: In the level The Maw, while the John blows up the engines of the UNSC Pillar of Autumn.In the level Keyes, when Captain Keyes orders John and Cortana to pull out.In the level 343 Guilty Spark, when John and the Marines are leaving the Flood containment facility.In the level Assault on the Control Room, briefly when John first commandeers an M808B Scorpion, when he encounters the tunnel entrance guarded by two Type-26 Wraiths, and when he battles the Plasma Rifle-wielding Sangheili Zealot.

In the level The Silent Cartographer, when John-117 comes to the Cartographer building for the first time.In the level Halo, when John-117 finds the last group of Marines in the Forerunner structures.The piece was primarily written by Michael Salvatori with additions from Martin O'Donnell. The rest of the sound is produced by a combination of drums, auxiliary percussion and hand-clapping, which is usually unheard of in many tracks written for Halo. It is composed nearly entirely of percussion, only having a deep bass note towards the middle of the piece and some vocals at the end of the piece.
