Gabe Follower, a YouTuber and dataminer exclusively exploring the backend of Valve’s titles, has now claimed that Half-Life 3 is very much real. The creator said he spent over three years datamining and working on finding out if Valve is making the title and shared his discoveries.

Gabe Follower first posted on Twitter today, Aug. 24, regarding his claims that “Half-Life 3 is real.” He also said that “Valve is trying to hide that we’re going back to Xen,” and how leaks point to this potential next Half-Life being a “semi-open world” game with a “weather system, day and night cycle,” where “smart NPCs that can talk to you.” He further stated it took him three years to compile a video showcasing all of these findings, which he shared on YouTube the same day.
