POLYBIUS is a fast, trippy tunnel shooter playable on a normal screen or in VR. 50 levels of blissful trance shooting action are set to a blistering soundtrack. The PS4 version was EDGE Magazine's VR GOTY in 2017, and the PC version of the game was even used as the basis for a NIN music video.
POLYBIUS supports VR on its own
VR support comes from the developer rather than a community conversion. Some games expose it in their normal settings; others use a separate VR edition or an official Steam beta branch.
