The Long Run

200px|right The Long Run is a musical piece included in the Halo: Original Soundtrack. It runs for 2:14.

This song is also heard slightly before, and during, the "Rolling Thunder" Section of Assault on the Control Room, when the player rides through the tunnels of Halo in a Scorpion Tank.

It also plays during the first part of the Warthog run on the level the Maw, and consists of a repetitive drumroll which is designed to underscore the nature of the escape and to make the player feel a sense of urgency.
