This is the VR flagship title that’s been teased and rumored for several years at Valve Ars reports that this is the VR game we were supposed to get in 2019, with the delay chalked up to infamous “Valve Time.” The game is a prequel, not a sequel - the long-desired, long-rumored, Half Life 3 remains a dead letter. Half-Life Alyx is designed for PC VR systems from companies like Oculus and HTC, though presumably Windows Mixed Reality sets and Valve’s own Index will both be supported.
