Which VR game, released by Valve in 2020, is set before the events of Half-Life 2?

Half-Life: Alyx is Valve’s VR game released in 2020 and set before the events of Half-Life 2.

The game follows Alyx Vance and her father, Eli, during the human resistance against the Combine occupation of Earth. Valve designed it exclusively for room-scale virtual reality, with interaction systems built around manipulating objects, operating equipment, and solving environmental puzzles.

Although it is a prequel to Half-Life 2, the game uses the same setting and continuity rather than retelling the earlier game’s campaign. Gordon Freeman does not serve as the playable character; players control Alyx.

The title was released for PC-compatible VR headsets in March 2020. It is often cited as a major example of a full-length, high-budget VR game rather than a short experimental experience.
