Half-Life fans have a fresh reason to get excited. Valve composer and audio designer Mike Morasky publicly mentioned HLX, the codename widely linked to a potential new Half-Life game, during a GameSoundCon panel. The reference came while he was discussing Valveโs audio technology and comparing how different projects use it.
Hearing the name from a Valve developer has renewed speculation around Half-Life 3. However, Moraskyโs comments leave the projectโs actual identity open.
In brief:
- Mike Morasky mentioned HLX during a GameSoundCon discussion about Valveโs audio engine.
- He referenced the project alongside Deadlock while discussing HDR audio systems.
- Fellow Valve developer David Feise appeared to respond with a quiet โnice work.โ
- HLX remains associated with Half-Life 3 through datamines and reports, with no official confirmation of that connection.
Mike Morasky References HLX Alongside Deadlock

The moment happened during the Q&A portion of a panel titled โValveโs Approach to an Open and Flexible Audio Engine.โ Morasky was answering a question about voice count when he brought up how individual projects handle their audio systems.
After explaining that Deadlock has its own version of HDR, Morasky added:
โHLX has its own version.โ
His colleague then appeared to whisper โnice workโ before moving the discussion along, suggesting attendees speak with the developers afterward about the broader topic.
The exchange quickly became part of the story. According to reports, his colleague also teased Morasky near the end of the panel for mentioning HLX only once. Whether the reference was an accidental slip remains open to interpretation.
HLX Is Linked to Half-Life 3
HLX has appeared in datamined Valve game files, prompting speculation that it refers to a new Half-Life project. Fans and reports have connected the codename to Half-Life 3, although Valve has yet to publicly confirm what the project actually is.
Morasky discussing HLX alongside Deadlock gives fans a direct developer reference to examine. His wording suggests familiarity with the projectโs audio setup, but it provides little insight into its scope or how far development has progressed.
Morasky offered no release date, gameplay details, or explanation of the HLX name. The panel therefore leaves the biggest questions unanswered, including whether the project will carry the Half-Life 3 title.
