It happened again: a Valve employee said “HLX” in public, and the Half-Life 3 rumor engine roared back to life. On October 21, during a GameSoundCon panel about how sound and music work in Source 2 — featuring Valve sound designers David Feise and Carlye Nyte alongside longtime Valve composer Mike Morasky — Morasky was asked about the engine’s open, flexible sound system and how it connects with other parts of the engine. His answer, as spotted by longtime Valve reporter Tyler McVicker, name-dropped two Valve projects:
“And in fact, I think Deadlock has their own version of HDR. You know, HLX has its own version, so on and so forth.”
Deadlock is Valve’s live shooter. HLX is not the name of any officially announced Valve game.
Why Three Letters Set the Internet on Fire
HLX is believed by fans to be the internal, non-public codename for the yet-to-be-announced Half-Life 3. Unless you’ve been following the last few years of Valve datamining and leaks, you’d have no idea what it is — because it has never been officially announced, teased, or even hinted at by the company. Fans only know about HLX thanks to over five years of datamining other Valve games for updates on what is reportedly the next mainline entry in the Half-Life series. The string first surfaced in early 2024 inside a Counter-Strike 2 update, bearing a very strong resemblance to “HLVR” — the codename that turned out to be Half-Life: Alyx. So hearing a Valve employee just casually say “HLX” on stage, in front of people and cameras, is, as Kotaku puts it, “kind of wild.”
Nineteen Years of Waiting
It’s been 19 years since the release of Half-Life 2: Episode Two, and yet the clamor for a Valve game with a number “3” in its title never dies. What makes this slip different from the usual annual rumor cycle — “Winter is closing in, The Game Awards are coming, and somebody at Valve said HLX,” as PC Gamer sighs — is the context around it. Eurogamer notes it follows “a swell of reports suggesting Half-Life 3 isn’t just real, its development is well underway.” And the HLVR precedent matters: the last time dataminers caught an internal codename, Half-Life: Alyx shipped months later.
Valve has said nothing, of course — it never does. But for a studio whose audio director apparently keeps HLX’s HDR pipeline in mind alongside Deadlock’s, the slip is the closest thing to confirmation the Half-Life 3 faithful have gotten in years.
