Sorry if I'm kinda new to this whole scene of non-steam vr games. What program do you use to run this game properly?
its a standalone game you dont need anything.
If you are using an Oculus, all you need is to have is the Oculus software, then open the game. If you have a Non-Oculus headset (Vive, Index, etc..), you need to open steamvr, and then open the game.
