Ring Fit Adventure's Ring-Con only works with Ring Fit Adventure officially, but modders/hackers made sure you could use the controller to play whatever the hell you wanted pretty much from day one. That paved the way for the video above, where someone decides to take on Dark Souls III with a Ring-Con.
While Ring Fit Adventure is designed to make you sweat, it seems other games are more than capable of doing the same thing. Dark Souls III already has you sweating during every boss battle, so why not through in some physical exercise to go with it?!
