Before this, we just knew that the game was coming out in March. Alyx marks the first new entry in the Half-Life series since Half-Life 2: Episode 2 released in 2007.
But this is not a sequel. Alyx takes place between the events of Half-Life and Half-Life 2. It also stars Alyx Vance, who served as a non-playable ally in the Half-Life 2 games. Gordon Freeman usually stars as the hero and player character in Half-Life games.

Valve had backed away from creating single-player gaming experiences for years, instead focusing on multiplayer titles like Dota 2 and Artifact. That left Half-Life in stasis, even as frustrated fans begged for Half-Life 3.
Well, this isn’t Half-Life 3, but it is finally a new installment in the franchise. It’s also a high-profile release for VR, which could spark interest in the technology (including Valve’s own Index headset).
