Half-Life: Alyx is a “feature length” VR game from Valve.

Set between the events of Half-Life and Half-Life 2, the title sees protagonist Alyx Vance and her father Eli secretly mount a resistance to the occupation of Earth by a mysterious alien race known as The Combine.

Valve says Half-Life: Alyx was “designed from the ground up” for Virtual Reality and “features all of the hallmarks of a classic Half-Life game,” including “world exploration, puzzle solving, visceral combat, and an intricately woven story that connects it all with the characters iconic to the Half-Life universe.”
