The Half-Life 3 rumor mill just got a fresh log on the fire, and this time it came straight from a Valve employee's mouth. At a recent GameSoundCon Q&A, Valve music designer Mike Morasky was casually breaking down audio work on the studio's games when he name-dropped the codename "HLX" out loud, then seemed to catch himself mid-sentence.
Here's what Morasky actually said while comparing audio systems across projects: "Deadlock has their own version of HDR, HLX has its own version, and so on and so forth." He trails off right after, and Valve sound designer David Feise is seen leaning over to whisper "nice work," which, yeah, reads less like a compliment and more like a colleague watching someone step on a rake in real time.
"HLX" isn't a new name to anyone who's been following this saga. Dataminers spotted it in Valve files back in 2021, and Valve insider Tyler McVicker (who also clipped and shared this latest slip) has been tracking it ever since, at one point claiming the project was "playable, end-to-end" and could land before the end of 2025. That obviously didn't happen, and the herd has heard "Half-Life 3 is basically here" enough times by now to know better than to set a calendar reminder.
What this moment does confirm, beyond HLX still being alive and apparently needing its own custom audio work, isn't much. But after Valve's first Episode 3 attempt died around 2009 and a full sequel reportedly got scrapped in 2013 or 2014 for running on an unfinished engine, even a half-second slip from a sound designer is enough to get the internet buzzing again. At this point the real race isn't Half-Life 3 versus Half-Life 2: Episode 3, it's Half-Life 3 versus the heat death of the sun.
