Valve today formally announced Half-Life: Alyx, a “full-length” game exclusively for VR. Half-Life is returning after 12 years, though Gordon Freeman seemingly is not and this isn’t Half-Life 3. Set between the events of Half-Life and Half-Life 2, this one stars future sidekick Alyx Vance in the years before Gordo’s return when she and her dad were building the resistance. And yes, this really is only for VR. Come watch the announcement trailer.
