A Walk in the Woods is a piece included in the Halo: Original Soundtrack. It was remade as Heretic, Hero in the Halo 2: Original Soundtrack, as "Another Walk," part of Released, in the Halo 3: Original Soundtrack, and as Walking Away in the Halo: Reach Original Soundtrack.
The only two levels in Halo: CE in which it can be heard is Assault on the Control Room, after the land bridge with two Banshees. It continues until the player reaches the bottom floor and Cortana tells the player to commandeer the Ghosts, and in Two Betrayals, during the cutscene after the last pulse generator is destroyed, until Cortana transports both her and John out.
The piece is dominated by synthetic woodwinds and a bass, which together start off solo before being joined by a steel drum at 00:16. Starting at 00:29, the woodwinds begin to fade out, allowing the drums to begin dominating the piece with a pulsing, regular beat. At 00:38, the winds join back in, re-establishing the melody of the piece. At 01:07, the melody fades out again, to be replaced by contrasting beats on cymbals; at 01:13, the melody returns, now with the cymbals laid over it to lend a secondary beat to the piece. At 01:43, the melody fades out for good, allowing the piece to gently conclude with cymbals sounding over the consistent pulse of the drum.
