Since this went a bit under the radar, if you're interested, you should definitely watch the new developer commentary by Dario Casali (a developer from Valve) which made a whole dev commentary playthrough of HL1 for its 25y anniversary!

Years and years of silence and then... boom! A full one hour documentary and content update. It's incredible to even think about it. Happy Birthday to my favourite videogame ever.
