Circle of Saviors is more fun than it should be. The cooperative hack-and-slash VR game glues you to a single spot, and you wield a shield and sword through HTC Vive controllers. Your buddy is armed with a crossbow (which is actually a Vive controller and a tablet screen). Meanwhile, you're immersed in the battlefield, as a green-screen room digitally maps everything to a TV for spectators to watch. Sure, I've seen this done before, but swords and goblins are way better than teleporting and shooting.
