Trivia

• Each and every cover of the soundtrack's eleven chapters corresponds with a scenery or element of focus from each respective chapter:
  • The cover of chapter one depicts the lofty Citadel under construction as seen from the balcony of Alyx' apartment block.
  • The cover of chapter two depicts the harrowing sight of a rotting cadavre suspended by tangled wires and Xen flora.
  • The cover of chapter three depicts the "all seeing eye", formed from nearby waste and debris by Gary using Vorti-energy to lead Alyx to his cottage.
  • The cover of chapter four depicts the seemingly unreachable and adamantine Vault at the hearth of the quarantine zone where Alyx is headed towards.
  • The cover of chapter five depicts the main street terrace in the sub-urban area where a Vortigaunt is kept as a living battery for the Vault, soon to be freed by Alyx.
  • The cover of chapter six depicts a combine solider as seen in the holographic agitprop displayed on various building blocks across City 17.
  • The cover of chapter seven depicts the blood-curling and grotesque mutated radge known to the player simply under the byname of Jeff.
  • The cover of chapter eight depicts an antlion found at the overrun Zoo which Alyx passes thru on her way to the Vault.
  • The cover of chapter nine depicts a Combine Advisor who guards the main luggage transported alongside resistance leader Eli Vance.
  • The cover of chapter ten depicts the inner core center-piece of the Vault where a high-importance prisoner is kept.
  • The cover of chapter eleven depicts the ominous G-man in a blurry frame.

• This is the first soundtrack released by Valve to be structured by chapter and order of play within the game, as all preceeding soundtracks have their tracks haphazardly listed.
  • For example Dark Energy within the Half-Life 2: Soundtrack is listed before Requiem for Ravenholm in the commercial track list despite the track first playing the next chapter over. Furthermore the 7th track, Pulse Phase, plays long after the high majority of the later tracks within the actual game.

• Kelly Bailey, despite not working for Valve anymore, has kept contact with Mike Morasky and guided the overall development of the soundtrack.
  • His artistic presence can be most clearly heard in the 72nd and final track of the soundtrack, HIRE.
  • Despite his known contribution to the soundtrack, the wiki is not legally allowed to credit him nor any other platform.

• From Here to There in Under a Second is named after a book that can be found in the game, written by Dr. Kleiner.

• Thirty-Seven After Six refers to a stopped clock outside of Russell's laboratory. This has been confirmed as the source of the name by Mike Morasky in emails.

• In keeping with tradition, a couple of tracks from older Half-Life games have been adapted and remixed for Half-Life Alyx's soundtrack. These tracks include Tri-Vector Pre-Reverberation, Processing Tripmines, and Infestation Ambiance.

• The seventh track "B3PbIBONACHOCTb" from the third chapter, despite apparently trying to approximate Russian, is not written in Cyrillic. This could be intentional in order to maximize compatibility with music systems that do not support Cyrillic characters. It is correctly written as ВЗРЫВООПАСНОСТЬ (Vzryvoopasnost') which can be roughly translated to "Explosion" or "Explosiveness".

• First track of the second chapter and 10th track overall, Quaranta Giorni, is written in Italian and translates to English as "forty days".

• Third track of the 9th album and 55th track overall, Let Me Talk To Your Super-Advisor, is a jest referring to the notorious phrase "Let Me Talk To Your Manager" often uttered by the infamous female archetype colloquially known as "Karen", representing a mean and narcissistic woman who always wants to have things her way and will threaten everyone out of her way. The humorous title is supposed to complement the scene in which a seemingly average woman talks with a bellicose attitude towards a Combine Advisor who could easily end her.

• Track 9 of the 11th album and 71st track overall, Consequences, contains mixed parts of Dark Interval from the Half-Life 2: Episode Two soundtrack.

• The soundtrack contains one song that doesn't appear in the game, the track in question being Exposing Hostile which only appears in the trailer for the game itself and is packaged as the first track of the first album, Entanglement. The game has only 71 tracks which if read backwards spells 17 as a nod to the City 17 sigil present on each and every main cover art for the individually released chapters as well as being the name of the city in which the action of the game takes place.

• The name of the 5th track from the 11th album, Ekpyrosis, refers to an ancient Greek belief which states that the universe exists within cycles and that at the end of each cycle the universe is destroyed and begins anew afterwards. The way this conflagration happens is by the universe being consumed by it's own fire.
