Behind the scenes
- The music was made with old equipment, including an analog 4-track recorder.
- Several tracks were cut from the soundtrack. One of them, titled "Mishaps In The Reactor Chamber Part 1 - Track 03", was reused by Jensen for the Half-Life 2 E3 2002 trailer. Jensen uploaded the tracks on his SoundCloud account in 2014 at the instigation the wiki after having been contacted several years prior about his credits for the music of the Half-Life 2 E3 2002 trailer. They have been removed since then.
