The gaming community is preparing to sound the alarm again after dataminers this week uncovered files in Counter-Strike 2 and Dota 2 that may point to continued work on the fabled Half-Life 3. Alongside a supposed leak from a voice actor, it’s the best evidence in years that we could eventually return to the Half-Life universe.

Content creator and dataminer Tyler McVicker detailed his findings in a YouTube video on Aug. 4, showcasing numerous files from recent CS2 and Dota updates that reference terms last seen in Half-Life 2 and Half-Life: Alyx. Some of these terms, McVicker explains, didn’t make the cut for the release of the Half-Life VR title but uncovered data confirms Valve has continued to test these features on the Source 2 engine.
