Half-Life: Alyx is a 2020 virtual reality (VR) first-person shooter developed and published by Valve. Between the events of Half-Life (1998) and Half-Life 2 (2004), players control Alyx Vance on a mission to seize a superweapon belonging to the alien Combine. Players use VR to interact with the environment and fight enemies, using “gravity gloves” to manipulate objects, similarly to the gravity gun from Half-Life 2. Traditional Half-Life elements return, such as physics puzzles, combat, exploration and survival horror aspects.
The previous Half-Life game, Episode Two, was released in 2007. After several failed attempts to develop further Half-Life projects, Valve began experimenting with VR in the mid-2010s, recognizing the demand for a large-scale VR game. They experimented with prototypes using their various intellectual properties, such as Portal, and found that Half-Life best suited VR. Alyx entered full production using Valve’s new Source 2 engine in 2016, with the largest team in Valve’s history.
