Half-Life: Alyx is the first Half-Life game since Episode Two in 2007, and Valve built it for a hardware category most publishers were still treating as a science project. It came out on March 23, 2020, for Windows, with a Linux release following on May 15, and it works with most PC-compatible VR headsets. It is not a spin-off or a side story, in this paper’s view. It is the real thing, and it is the strongest argument anyone has made that VR can carry a full-length game.

Alyx Vance and the gravity gloves
You play as Alyx Vance, a Resistance member fighting the Combine, the alien empire that conquered Earth. The game is a first-person shooter played entirely in virtual reality. Combat, puzzles, exploration and narrative all run through the headset.
The gravity gloves are the central mechanic. They let you snatch objects from a distance, the same trick the gravity gun pulled in Half-Life 2. You use them for supplies, for interfaces, for throwing things, for weapons. Valve designed every one of those interactions around motion controls, and it shows.
Alyx supports all SteamVR-compatible headsets, including the Valve Index, HTC Vive, Oculus Rift, Meta Quest and Windows Mixed Reality headsets. Valve said it had no plans for a non-VR version, because the gameplay was built for VR from the ground up. The game also supports user mods through the Steam Workshop.
Jeff, the blind monster
The horror is where Half-Life: Alyx separates itself from its predecessors. Ammunition is scarce. Encounters are frightening. In one chapter you meet Jeff, a blind monster who hunts by sound. You have to move quietly and throw objects to distract him.
Alien spores in that area make Alyx cough. You stop it by holding your hands over your mouth. That is the whole idea of the game in one sequence: a mechanic that only works because your body is the controller.
Valve did not soften this for a wider audience. The Jeff chapter is the most memorable stretch of the game, and it is memorable because it is uncomfortable.
Ozioma Akagha replaces Merle Dandridge
The casting is more interesting than most game credits. Merle Dandridge, who voiced Alyx in Half-Life 2, recorded initial sessions in March 2019. Playtests showed the character needed a younger voice, so Ozioma Akagha was cast in September 2019.
Akagha avoided playing irritation. “You don’t want someone in your head that sounds irritated with you,” she said of the performance.
James Moses Black plays Eli Vance, taking over from Robert Guillaume. Rhys Darby plays Russell, the inventor who rescues Alyx, and he added comedic elements to the role. Tony Todd returns as the vortigaunts, Mike Shapiro returns as the G-Man, and Ellen McLain voices the Combine broadcasts.
Shapiro recorded his lines in a single 20-minute take, with pickups in 2019. Cissy Jones and Rich Sommer were cast on the suggestion of writer Sean Vanaman, who had worked with them on Campo Santo’s Firewatch.
A vault, a superweapon and the G-Man
The plot sits between Half-Life and Half-Life 2. The Combine runs a police state. In City 17, Alyx and her father Eli are taken into Combine custody during a crackdown on the Resistance. Russell rescues Alyx and tells her the Combine plan to ship Eli to Nova Prospekt for interrogation.
In the quarantine zone, Alyx meets a vortigaunt named Gary, voiced by Tony Todd. He asks her to save his fellow vortigaunts and predicts Eli will die. Alyx derails the train carrying Eli. Gary pulls him from the wreckage.
Eli learned in custody that the Combine store a superweapon in a vault inside the quarantine zone. He sends Alyx to retrieve it. She fights through Combine forces and shuts down a power station holding the vault aloft, then finds each station is powered by an enslaved vortigaunt. She frees one, who promises the vortigaunts will disable the rest.
Eli warns her the vault is a prison built to contain something the Combine found. Russell guesses it holds Gordon Freeman. Alyx crashes the vault to the ground. Freeman is not inside. The G-Man is.
The G-Man offers his services as payment for freeing him. Alyx demands he remove the Combine from Earth. He says that would not serve his “employers.” He shows her a vision five years in the future instead.
Source 2 and a 2016 production start
Valve started Alyx in 2016 on the Source 2 engine, with the largest team in the company’s history. That team included members of Campo Santo, the studio Valve acquired in 2018.
VR shaped nearly everything: level design, combat, movement, pacing. Valve planned to ship Alyx alongside its Index headset in 2019, then delayed it to rewrite the story after internal feedback.
The previous Half-Life game, Episode Two, came out in 2007 and ended on a cliffhanger. Valve tried several times to make another one and could not settle on a direction. In the mid-2010s the company began experimenting with VR and identified demand for a major VR game. It prototyped with Portal and other series before deciding Half-Life fit VR best.
That is the honest history of this game. Valve had spent years unable to settle on a direction for the series, and VR gave it one.
What Half-Life: Alyx gets right
The graphics, the voice acting and the physicality of the interaction are the strongest parts. The gravity gloves turn looting into a small skill. The Jeff chapter turns a monster encounter into a puzzle about your own body. The vortigaunt power stations give the combat a weight this paper found the series had not carried before.
Here is what matters, ranked:
- The gravity gloves, because they make VR feel like a tool rather than a gimmick.
- The Jeff chapter, because in this paper’s view it is the stretch that depends most on the headset.
- Ozioma Akagha’s Alyx, because the recasting was correct and the performance carries the game.
- The G-Man ending, because in this paper’s reading it repositions the series without undoing what came before.
- The Source 2 engine work, because it is the technical floor everything else stands on.
The weak point is the ending’s reliance on a character who has always been a tease. The G-Man reveal lands, but it lands as setup. Valve delayed this game to rewrite the story, and the rewrite still ends by pointing at something else.
Half-Life: Alyx is not a compromise between a VR demo and a real game. It is a real game that happens to require a headset, and the requirement is the point. Valve spent four years and its largest team proving that the medium can hold a full campaign with combat, puzzles and a story worth following. It holds.
The question the game leaves is not whether VR works. It works. The question is whether Valve will follow it, and the company has not said.
