Demise is a hard game because aside from shooting floating robo-things, you have to not puke. It's an FPS that shows you everything around you at the same time: an entire 360 degree view mapped onto one screen.
For whatever reason you can only play Demise with a controller, and the slightest pressure on the analog stick swiftly spins the bulbous grey hallways around your head, signaling to your stomach that the deities have forsaken humanity and the digestive organ rebellion has begun. I played two hours of Half-Life 2 on an Oculus Rift DK1 and felt fine. It took two minutes before I was hammering Esc—ineffectively—to try to make Demise go away.
If you're up for the challenge, it's a cool idea, albeit one I and I'm sure others have experimented with by cranking the FOV up in old shooters—not quite the same thing, but with similar gut trouble. (This is how (opens in new tab) cool people play Quake 2.)
Demise was created by Yan Knoop, Keano Raubun, and Mikkel Bøgeskov Svendsen, and Jack Beeby during last year's Nordic Game Jam. We noticed it and gave it a go thanks to Chris Priestman's recent tweet (opens in new tab). You can download it free here (opens in new tab).
The 2017 Nordic Game Jam (opens in new tab) is happening this April. I look forward to seeing what comes of it, so long as it isn't the bagel I had that morning.
