Valve's Mike Morasky Says 'HLX' Out Loud at GameSoundCon and Half-Life 3 Fans Lose It Over One Slip

By CriticalPixel · 2026-10-25

Valve has spent the better part of a decade training people not to believe a single thing about Half-Life 3, and then one audio designer at a conference undoes the whole policy by accident. During a Q&A panel at GameSoundCon, Valve's Mike Morasky was explaining how the company handles sound, mentioned that Deadlock uses a particular type of high dynamic range audio, and added that HLX uses its own kind of HDR. IGN picked up the clip and ran it, which means the codename dataminers have been chewing on since Half-Life: Alyx just came out of a Valve employee's mouth in public. For a company that treats silence as a business model, that is a rare crack in the wall.

What Morasky Actually Said

The talk is called Valve's Approach to an Open and Flexible Audio Engine, it was streamed on October 21 through the ProaVirtual channel, and it runs just under 70 minutes. It is a technical session for audio people, and the HLX line is a throwaway aside about how HDR is handled in different projects. According to IGN, once the letters left his mouth Morasky pretty much stopped talking, and a colleague sitting next to him quietly said "nice work." Whether that was a joke at his expense or ordinary panel banter is impossible to tell from the outside. What he did not give anyone is a genre, a platform, a release window or a single line about gameplay.

Why Three Letters Matter

IGN explains the background: dataminers have found references to a project called HLX in Valve related files for years, and the working assumption is that it means Half-Life 3, because nobody has been able to tie the name to any other Valve project. Until now that was inference built on file names. VGTimes points out that this appears to be the first time anyone from Valve has said the codename out loud in public, and also claims this is the third time Morasky has let slip that a new Half-Life exists. We could not verify that third-slip claim on our own, so treat it as VGTimes' count rather than a settled record. Even without it, a named Valve audio designer comparing HLX to Deadlock in the same breath is more than a filename in a leaked build.

Here is the careful reading. IGN says the mention does seem to confirm that HLX is a project still in active development at Valve, which is a real step up from a rumor that might have been a dead folder. It does not confirm that HLX is Half-Life 3, and it does not say the game is close. Our own inference, and only that, is that a project with its own HDR audio treatment is far enough along to have engine level decisions made for it, but Valve has plenty of internal projects that never ship. Half-Life: Alyx launched on March 23, 2020, and its ending set up Gordon Freeman's next adventure with a massive cliffhanger, so players have now waited more than six years for the follow up.

How the Internet Took It

Replies under IGN's post read like a fanbase that has been burned before and cannot help itself. One reply joked that Valve's whole marketing plan is one composer saying three letters. Another said that accidentally mentioning Half-Life 3 should count as early access. A third admitted to being fooled by Half-Life 3 too many times and still being hyped, and another called a codename slip the most Valve thing ever while pointing out that it is still not a release date. We only sampled a handful of replies, so this is a vibe check and not a consensus, but the mood is hope with a lot of scar tissue on top.

The CriticalPixel Take

Valve is the only company on earth that can turn a footnote in an audio talk into a global news cycle and then say absolutely nothing for the rest of the week. There is no trailer, no date, no store page and no statement, and that silence is a choice. Fans are doing the free marketing, the dataminers are doing the free leak work, and Valve gets to keep the mystery without lifting a finger. That works well for Valve and badly for anyone who wants an actual answer.

IGN floated The Game Awards as a possible reveal window and then called it a longshot, which is the right amount of caution. Treat this as a confirmation that something with the HLX label exists and is alive, nothing more. If Valve ever wants to make fans believe a Half-Life announcement, it can do it with one trailer. Until then, the only thing to watch for is a Valve statement, new files showing up in Steam database updates, or another conference talk where somebody forgets the unwritten rule.

For now the situation is simple. Half-Life 3 is still unannounced, HLX is still an unconfirmed codename, and a man talking about HDR audio gave the community its best accidental clue in years. Keep the hype on a leash, keep your wallet closed, and enjoy the show.
