The fight against the Combine begins
Set between the events of Half-Life and Half-Life 2, Alyx Vance and her father Eli mount an early resistance to the Combine's brutal occupation of Earth.
The loss of the Seven-Hour War is still fresh. In the shadow of a rising Combine fortress known as the Citadel, residents of City 17 learn to live under the rule of their invaders. But among this scattered population are two of Earth's most resourceful scientists: Dr. Eli Vance and his daughter Alyx, the founders of a fledgling resistance.
You are Alyx Vance, and you’re about to spark a revolution
You and your father were relocated to City 17. In the years since, you've continued your clandestine scientific activity—performing critical research, and building invaluable tools for the few humans brave enough to defy the Combine.
Every day you learn more about your enemy, and every day you work toward finding a weakness.
A full-length game built from the ground up for virtual reality
Lean around a broken wall and under a barnacle to make an impossible shot. Rummage through shelves to find a healing syringe and some shotgun shells. Manipulate tools to hack alien interfaces. Tear a headcrab off your face and throw it out the window. VR was built for the kind of gameplay that sits at the heart of Half-Life.
Half-Life: Alyx supports a variety of play environments, locomotion methods, and input devices.
Play on any SteamVR system
If you have VR hardware that works with a computer, then it works with SteamVR.
If you don’t yet own any VR hardware, now's the time. Headsets support different sets of features, so the experience will vary between them. Half-Life: Alyx was built hand in hand with Valve Index, which is the highest fidelity option on the market, but the game works great with Vive, Rift and Windows Mixed Reality too. Check out the different options to choose which one is right for you.
