Half-Life 3 speculation reignited by Valve dev mentioning three sweet little rumored codenamey letters amid technical chat about video game noises
Valve composer Mike Morasky casually referenced HLX during a technical panel, reigniting speculation that it may be a codename for Half-Life 3, though no official confirmation was provided.
Valve composer Mike Morasky mentioned HLX during a GameSoundCon panel about game audio, describing it as one of three components used to create HDR in games. The comment came roughly an hour into the discussion, framed as a technical explanation rather than an announcement. Morasky’s remarks were delivered in the context of comparing different implementations of HDR across projects, including Deadlock and HLX.
The acronym HLX has previously surfaced in a Counter-Strike 2 update data string, where it appeared alongside other codenames like HLVR for Half-Life: Alyx. This recurrence has fueled speculation that HLX could be tied to a future Valve project, particularly given the pattern of using three-letter codenames for Half-Life entries. Morasky’s co-panelist, David Feise, appeared to react subtly to the mention, suggesting awareness of the potential significance.
Morasky has a history of referencing HLX in past contexts, though his comments during the panel were not framed as intentional reveals. The exchange occurred during a broader discussion about audio optimization in games, with no direct confirmation of Half-Life 3’s development status. The panel’s technical focus limited the scope of the conversation to audio engineering rather than game announcements.
Former Valve writer Chet Faliszek stated he would not be involved in writing Half-Life 3 if it were in development, adding a layer of ambiguity to ongoing speculation. While the HLX reference has drawn attention, no official details about a new Half-Life title have been confirmed by Valve. The comments remain speculative, rooted in past patterns rather than new evidence.
