Farthest Outpost is a song included in the Halo 3: Original Soundtrack. It contains the tracks Farthest Outpost, No Time for Sightseeing, and Make Them Pay. It plays during the beginning of the Halo 3 level The Ark. The beginning of the song is based mainly on choir and strings. It is similar to the song In Amber Clad from Halo 2. At around 0:40, drums become the dominant instrument. Later on, the melody is taken over by strings again, playing the Arbiter's theme. After that, a section from the songs, Out of Shadow and the Halo 3 version of Perilous Journey, Make Them Pay will play.
The song runs for 5:14.
At the beginning of the Halo 3 version of Perilous Journey, a heavy bass drum is audible in the background playing seven beats before resting and then repeating.
The first part with the drum and bass line starting at 0:46 was a random menu song in Halo 3: Mythic.
