In early 2025, there were rumors circulating that Half-Life 3 is in development and nearing completion. Tyler McVicker, a well-known insider, mentioned that the game might be officially announced later this year after a period of silence.
McVicker, known for sharing insights about Half-Life: Alyx before its official announcement, revealed that the new installment in the series is progressing rapidly. Referred to as ‘HLX’ internally, the game has recently undergone updates and improvements, signifying a new stage in its development.
Details about the elusive Half-Life 3 are derived from Source 2 files, accessible through the Counter-Strike 2 update launched on October 15. The company frequently hints at upcoming projects within updates for existing games on the market.
Half-Life 3 ought to be revealed through a straightforward tweet.
The well-known insider reports that according to Source 2 files, the HLX project has been undergoing several months of refinement and enhancement. Valve has recently implemented an automated system that optimizes system resources and makes modifications to aspects such as sound and liquid simulation.

The developer typically initiates these procedures only when confident that a title is prepared for launch. Therefore, Vickers is optimistic about the likelihood of Half-Life 3 being developed and accessible to the public in the near future.
The unveiling of Gordon Freeman’s next journey should not coincide with a significant event like the Game Awards, according to an industry insider. Valve may opt for a strategy akin to the one used for confirming the existence of Counter-Strike 2 through a message in X.

The developer’s track record suggests that if Half-Life 3 is announced, it will quickly be available to fans. It remains uncertain whether the game will follow traditional shooting game conventions or if the company has introduced new gameplay elements to set it apart in the current market.
