Today's update brings VR support for all platforms (Oculus Rift, HTC Vive, OSVR). If you have your headset, put it on and let us know your thoughts from inside the cockpit. :-)
To start the game in VR mode instead of regular desktop mode please open your Steam library, select "Space Merchants: Arena" and hit Play. Select your VR from the list (SteamVR=OpenVR - HTC Vive, OSVR, Oculus Rift; OculusVR - Oculus Rift with Rift Audio etc.)
