Overview
Half-Life: Alyx is a first-person VR action-adventure game developed and published by Valve, released on March 23, 2020. The game takes place between the events of Half-Life and Half-Life 2, following Alyx Vance and her father Eli as they mount an early resistance against the Combine, an alien force that has occupied Earth since the Black Mesa incident. It runs exclusively on PC-compatible VR headsets via Steam.
Playing as Alyx, you navigate Combine-controlled city sectors, scavenge for resources, solve environmental puzzles, and fight off soldiers and creatures using a range of weapons. The game spans roughly 15 hours on a first playthrough, with a structure that blends tense combat encounters with quieter exploration and puzzle sequences. Valve built it from the ground up for VR, meaning every system, from reloading pistols to opening drawers, is designed around physical hand movement rather than button shortcuts.

Gameplay and mechanics: how does Half-Life: Alyx actually play?
The core loop revolves around three things: combat, exploration, and puzzle-solving. Alyx carries pistols, shotguns, and a rapid-fire weapon across the campaign, and reloading each requires physically ejecting a magazine, grabbing a new one, and slapping it in. That physicality extends to every interaction. Picking up a health syringe, prying open a vent, or tossing a bottle at a distant switch all happen through tracked hand movement.

Key mechanics include:
- Gravity gloves for pulling objects from a distance
- Manual weapon reloading with motion controls
- Environmental puzzle-solving using physics
- Resource scavenging to upgrade weapons
- Combine soldier and creature encounters
The gravity gloves, Alyx's signature tool, let you flick objects toward your hand from across a room. They give the game a rhythm similar to the original Half-Life 2's gravity gun, but adapted for a VR context where the physical gesture of catching a thrown item lands with real weight.
World and setting
The game is set in City 17, the same Eastern European-styled urban environment familiar from Half-Life 2, but seen years earlier under heavier Combine control. Apartments are sealed. Streets are patrolled. The population is corralled and monitored. Valve's environmental storytelling fills apartments and back alleys with the kind of detail that rewards players who take the time to look around.

The story positions Alyx and Eli as scientists-turned-resistance-founders, using their technical knowledge to chip away at Combine infrastructure. The narrative is fully voiced and scripted, running through a series of set-piece moments that escalate toward a genuinely memorable ending. Half-Life fans will find direct story connections to Half-Life 2 here.
Technical achievement
Half-Life: Alyx supports all major PC VR platforms, including Valve Index, HTC Vive, Oculus Rift, and Windows Mixed Reality headsets. Valve Index owners get the most out of the finger-tracking controllers, but the game is fully playable on other hardware. The Source 2 engine handles detailed environments and physics simulation at VR framerates, which is no small task given how demanding the headset requirements are for comfortable play.

Impact and legacy
Few VR games before or since have matched Half-Life: Alyx in scope or execution. It won multiple Game of the Year awards in 2020 and sits at an overwhelmingly positive rating on Steam with tens of thousands of reviews. The Steam Workshop support means a substantial modding community has extended the game's life well beyond the base campaign, with custom maps, total conversions, and community-made levels available for free. For anyone with a compatible VR headset, Half-Life: Alyx remains the clearest argument that VR action games can deliver the same depth and craft as any flatscreen release.
