Remko van Brakel recently released his HTC Vive remake of Duck Hunt. That is super awesome but what really messed with me today is learning of how to play it using a Vive emulator.
Shout out to the founder of Destructoid for making me aware.
"The game works on the Vive, but of course there's ways to emulate the Vive if you don't have one. I recommend Riftcat.com with a cardboard viewer to demo these things on the smartphone you already own. If you don't have bluetooth controllers either, you should stop buying Pokémon buttplugs and get a proper nest of just-in-case cables. I wrote a guide on how to use a $30 Leap controller in VR to emulate Vive's motion controllers.
