After years of endless “is it coming or not?” debates, Half-Life 3 is once again making headlines and this time, the rumors sound more convincing than ever. Sources close to Valve claim that a mysterious project codenamed “HLX” has entered the optimization phase, with the first trailer reportedly in production.
The strongest hints of progress come from recent technical updates to the Source 2 engine, which focus on faster loading times, refined physics, and improved enemy AI reactions. These kinds of changes typically suggest that a game is entering its final polish stage when the foundations are done, and only finishing touches remain.

While it’s not officially confirmed that HLX is Half-Life 3, insiders say the codename has been used internally for years. Reports indicate that internal testing is underway, most of the story mode is complete, and marketing materials are already being prepared. Some leaks even claim Valve plans to reveal the trailer by late 2025.
Still, Valve remains characteristically silent. Whether HLX is a direct sequel to Half-Life 2 or a new, possibly VR-focused spin-off remains unknown. Fans are split; some hope for a true continuation, others expect a side project in the Half-Life: Alyx vein. For long-time fans, Half-Life rumors are nothing new, but this time, the signs feel more tangible. The increased Source 2 activity suggests something big is brewing inside Valve’s labs.
The question is: Has the day finally come? Is Half-Life 3 still a myth or is it finally preparing to step into reality by the end of 2025? Share your thoughts and stay tuned to both X and VGNW for the latest updates.
