Valve Slip-Up Confirms HLX Project

Mike Morasky, Valve's veteran sound designer, slipped a reference to HLX during a Game Sound Con panel on Oct. 22, 2026. He was explaining how Deadlock's HDR audio differs from HLX's own HDR system before abruptly stopping. A nearby colleague whispered, "Nice work," sparking speculation that Morasky may have revealed an ongoing Half-Life 3 codename. Datamining earlier this year had already unearthed HLX references, leading fans to equate it with the long-rumored third entry. The slip suggests Valve still develops HLX, but no release date has surfaced, and it could be years away. If HLX is Half-Life 3, its turnaround after Alyx could hint at a Game Awards debut, but that's a longshot.
