List of Half-Life 1 music

This article or section needs to be cleaned up to conform to a higher standard of quality because:

The information from Combine Overwiki should be added, such as when the tracks play in the vanilla games.

For help, see the VDC Editing Help and Wikipedia cleanup process. Also, remember to check for any notes left by the tagger at this article's talk page.

This page documents the music available in Half-Life, Half-Life: Opposing Force, and Half-Life: Blue Shift, as well as mods using their content.

Todo: Document Half-Life: Source (and by extension, Half-Life Deathmatch: Source).

Half-Life

The following tracks are available in Half-Life and most first-party GoldSrc games (not in ), as well as mods for them that do not override the vanilla music files.

Note:

• Track numbers based upon original retail CD track IDs, which are also used by target_cdaudio and trigger_cdaudio. Track 1 is a data track in the original retail CD. Album releases use the same track order, but start at 1 instead of 2.
• Track names taken from official album releases, as found on Steam, iTunes, and the official YouTube Music uploads.
• Some tracks were reused in Half-Life 2, either in their original form, or remixed; these have been indicated appropriately below.

Important: Sven Co-op uses a different naming system. All tracks are named Half-Life##.mp3 wherein ## is the CD track number minus one.
