Dreadhalls is a horror dungeon crawler for Virtual Reality (HTC Vive, Oculus Rift and Gear VR).
You are trapped deep inside a massive dungeon. Explore it, survive it, and find a way to escape. Your only weapons will be stealth, your own courage, and a faint light.
You can get Dreadhalls on Steam at: http://store.steampowered.com/app/589200
Or at the Oculus Store in both the Gear VR and Oculus Rift.
