- Fellow developer David Feise appeared to react to the remark before returning to the panel’s subject.

A Valve developer mentioned HLX during a public presentation, renewing attention to rumors of a new Half-Life game. Mike Morasky, a composer and audio artist at Valve, mentioned the codename during a GameSoundCon panel on the studio’s audio systems. Fellow developer David Feise appeared to react to the remark before steering the discussion back to its original subject.
The exchange has since circulated on social media, where fans have linked HLX to the long-rumored Half-Life 3. However, the comment doesn’t establish whether the project is a new entry in the series, what stage of development it’s in, or when Valve might reveal it. The company has not officially announced Half-Life 3 or confirmed that HLX’s the project.
Valve Developer Mentions HLX During GameSoundCon Panel
The remark came during a panel titled Valve’s Approach to an Open and Flexible Audio Engine. Morasky was discussing how the studio handles audio across its games when he referred to the systems used by different projects. “In fact, I think Deadlock has its own version of HDR.
HLX has its own version, and so on and so forth,” Morasky said. The comment drew attention because HLX has been linked to an unannounced Valve project for several years. Feise, who was sitting beside Morasky, appeared to whisper “nice work” after the remark. He then redirected the conversation to audio groups rather than discussing HLX further.
Synth Potato described it as a possible accidental confirmation of Half-Life 3. That interpretation has attracted attention, but the original remark was limited to HLX. Morasky did not identify the project by its rumored title or discuss its gameplay, story or release plans.
GamesRadar+ also highlighted the exchange, including Feise’s apparent reaction. A further moment at the end of the panel reportedly captured Feise telling Morasky, “Good job, you only said HLX once,” to which Morasky replied, “I did?”. The exchange has added to speculation that HLX is an internal project name. However, a developer mentioning a codename does not confirm the project’s final name or nature. Valve has not announced that HLX is Half-Life 3.
Why HLX Has Been Linked to Half-Life 3
Dataminers and Valve followers have discussed HLX since references to the codename surfaced in game files. As PC Gamer previously reported, the name drew attention in early 2024 after it appeared in a Counter-Strike 2 update. Observers compared it to HLVR, the codename associated with Half-Life: Alyx, but that similarity didn’t establish what HLX represented.
The speculation has continued because Valve has not released a direct follow-up to Half-Life 2: Episode Two, which launched in 2007. The company returned to the series with Half-Life: Alyx in 2020, a virtual reality prequel that revisited the franchise’s setting and characters but did not serve as a conventional third mainline entry.
A separate discussion on r/GamingLeaksAndRumours focuses on the hot-mic exchange at the end of the presentation. These posts show the community response, but they don’t provide independent evidence of a release date or an official announcement.
In another recent PC gaming bit, Xodus Nexus added experimental Steam Deck support for PC Game Pass games on Linux, giving players another option for accessing selected Windows games on Linux-based devices.
For now, the GameSoundCon remark adds another public reference to a codename fans and dataminers already follow. It doesn’t confirm whether HLX will become Half-Life 3, whether it will continue Gordon Freeman’s story, or when Valve might reveal it. Until the company provides further details, the project’s identity and release plans remain unconfirmed.
