Support for the HTC Vive has been added to Metro Warp!
For now, that means an identical control scheme to the Oculus version. You'll need a controller for the best experience, although it works with just a keyboard. The Vive wands are not currently supported.
Look around to select things, and use either A/X buttons on a controller, or Enter/Return on a keyboard to push. WASD/joysticks to rotate.
To launch in VR for the Vive, either launch from the SteamVR dashboard, or pick "Launch Metro Warp in Steam VR Mode" when launching.
