  • 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"
