PlayStation VR Exclusive is coming to PC.
The Polybius Shootup hit the PlayStation Store last May and was well received by the press (the game has a Metacritic rating of 84). Polybius can be played with or without a VR headset.
The game now has its own Steam page, and the PC version of Polybius is slated for release later this year. To play in VR mode, you need an Oculus Rift headset. The cost of Polybius is currently not specified.
