Fallout Score

The Fallout score was composed by Mark Morgan for Fallout. On May 10, 2010, it was released together with the Fallout 2 soundtrack on Morgan's Vault Archives album.

Followers' Credo (Thunder)
Followers' Credo plays while the Vault Dweller is in the Boneyard Library (Followers of the Apocalypse base) in Fallout, and while the Chosen One is in the Enclave Oil Rig or in the Guardian of Forever special encounter in Fallout 2.

The track was originally composed for another game, Netstorm. When being added to the Fallout soundtrack, the track was simply retooled to remove the periodic thunder sound effects and deep rumble. This also shortened the song by a full minute from 3:45 to 2:45.
