Half-Life 3 is playable end-to-end, according to a new report from Valve insider Tyler McVicker. The long-awaited sequel, codenamed HLX, has reportedly reached a stage where it can be played from start to finish, with extensive internal playtesting underway.
HLX enters full playtesting phase

McVicker, known for his accurate insights into Valve’s projects, revealed that HLX is being tested extensively by a sizable group. He stated, “HLX is being playtested so religiously and so widely that there are individuals that will just talk.” This level of testing suggests the game is in its final stages of development, focusing on optimization and polish.
Half-Life 3 is not a VR title
Unlike Half-Life: Alyx, HLX is not a VR-exclusive game. McVicker emphasized that the upcoming title is designed for traditional gameplay, making it accessible to a broader audience. This decision aligns with Valve’s intent to return to the series’ roots while potentially incorporating innovative gameplay elements.
Potential announcement and release timeline
While Valve has not officially confirmed HLX’s development, McVicker speculates that an announcement could occur in the summer of 2025, with a possible release in the winter. He noted, “This is the furthest it’s ever been. Period. The game is playable end-to-end, period.” This progress marks a significant milestone in the game’s development journey.
Half-Life 3 narrative and gameplay details remain under wraps
Specifics about HLX’s storyline and gameplay mechanics are scarce. McVicker mentioned that he avoids discussing story-related information to prevent spoilers. However, he acknowledged that some plot details have surfaced due to the extensive playtesting phase.
Valve’s commitment to innovation
Valve has historically aimed to push the boundaries of gaming with each Half-Life installment. While details about HLX’s innovative features are limited, the company’s track record suggests that the upcoming title may introduce new mechanics or storytelling techniques that advance the medium.
The anticipation builds
The news that Half-Life 3 is playable end-to-end has reignited excitement among fans. As the gaming community awaits official confirmation from Valve, the prospect of finally experiencing the next chapter in the Half-Life saga seems closer than ever.
