The claim
'HLX', a codename first found in 2024 game files, is an active Valve project, widely assumed to be a new Half-Life game.
Why we rated it Rumor
On Oct 22 Valve composer Mike Morasky mentioned 'HLX has its own version' of Valve's audio HDR system during a GameSoundCon panel, and a co-panelist's reaction suggested it was a slip. That is the first time a Valve employee has said the name publicly, so the project likely exists, but nothing confirms it is a game, let alone Half-Life 3, or when it might be announced. Half-Life rumors have a long record of not panning out.
