Half-Life: Alyx will be a single adventure in the familiar universe, no multiplayer yet out of the question. Valve is not interested in this. Robin Walker, one of the developers of the VR shooter, wrote about it to The Verge.
Half-Life: Alyx will be a traditional single adventure for the series.
Robin also noted that Valve works closely with focus groups. Today, players spend about 2-3 hours at Half-Life: Alyx, after which they take a break. This is a great result. The developers evaluate the players’ reactions and emotions. During the development process, Valve tracked the statistics of game sessions in the VR Titles and approached the development of levels with this data.
Half-Life: Alyx is scheduled for release in March 2020.
