Half-Life: Blue Shift soundtrack

	This article has been cleaned up as part of the Cleanup Project, and has its review pending.
	After review, it will be given a safe, good or featured article status.

There is no proper Half-Life: Blue Shift soundtrack, as the Half-Life soundtrack by Kelly Bailey for the Dreamcast version, and Opposing Force soundtrack by Chris Jensen for the Windows port were reused.

Trivia

Originally, the Steam versions of Blue Shift and Opposing Force did not use their original soundtracks, but instead the Half-Life soundtrack by Kelly Bailey. This was, however, corrected when both games converted into the SteamPipe distribution system.
