Rock Anthem for Saving the World is a piece included in the Halo: Original Soundtrack.

Appearaces
It is heard in its full form on Silent Cartographer just after the Master Chief has activated the map. The initial part of the piece is later heard at the base of the Control Room on the level Assault on the Control Room. It also begins playing when the bottom of the control room is reached on the level Two Betrayals. It is also considered the main theme for the games, although it only appears in this arrangement on the Halo: CE soundtrack. It does reappear in the Halo 2 soundtrack, on the songs Reclaimer and Unyielding, and again on the Halo 3: Original Soundtrack in the track To Kill a Demon.

It runs for 1:20, but is also listed as being 1:17 seconds long, a reference to the Master Chief.

Trivia

 * The song is the same length as Prepare to Drop and Remembrance, at 1:17.
 * In Halo 3: ODST Campaign, at the Coastal Highway level, before driving the Warthog, if you enter the frontal nearby underground passage, the exact same theme will play. Additionally, in the same zone, there are several rocket launchers with 998 ammo.
