Subnautica already has VR. It looks great in VR but the interface is very clunky. They didn't do a good job with the VR controls unfortunately. A real shame since the rest of the game is very well polished otherwise. Fantastic experience on a normal screen, and very cool in VR but if you're trying to mess with the interface it becomes a chore.
Maybe there's a VR mod that improves interface stuff.
