Half-Life Alyx released about a month and a half ago and received universal acclaim from both critics and fans. Valve didn't discuss sales figures, though the game peaked at around 43K concurrent players on launch day, basically matching the most popular VR game, Beat Saber.

The purpose of Half-Life Alyx was always to drive VR hardware adoption, anyway, and in that regard, it may have done even better. A new analysis by Road to VR suggests almost a million new VR headsets were connected to Steam in April compared to the previous month, based on the latest Steam hardware survey.
