Believe it or not, after a dozen years on the shelf, the Half-Life series is finally making it return. First announced in name only earlier this week, Valve has just pulled the curtain back on Half-Life: Alyx, which they’re positioning as the killer app for their SteamVR platform. The trailer is brief, but it shows pretty much everything you’d expect from a new Half-Life game, including plenty of face-huggers, Combine soldiers, and our old friend G-Man. The Source 2 engine looks to be acquitting itself well, as we get a glimpse of some vistas we rarely see in VR-exclusive titles. You can check out the debut trailer for Half-Life: Alyx, below.
