Moondust is a first-person sci-fi action game for HTC Vive virtual reality devices, set in the Portal universe. You take on the role of one of the robots that Aperture Science sends to the moon. The game requires you to complete a few simple tasks, such as crushing lunar rock and riding a radio-controlled buggy. The main goal of the game is to show what Valve's new VR controller called Knuckles EV2, which is capable of tracking pressure and finger position, is capable of.
