Here's some great news that was reported by Polygon. No matter what HMD you purchased EVE: Valkyrie for, whether it be for the Oculus Rift, HTC Vive, or Sony PlayStation VR, you'll be able to team up and play against others when the game's released for all platforms.
EVE: Valkyrie has been somewhat of a VR darling and seeing such a high profile game with a great company behind it allow people to play together no matter what HMD or platform they are on is amazing.
EVE: Valkyrie will be a launch title for the PlayStation VR and it's currently out now on the Oculus Rift with the HTC Vive version coming soon.
