Street Fighter is a game of precise input and output -- a delicate tightrope walk of fistic physicality. Hacked together Steam controller motion controls? Maybe not the best idea. And yet...
On a whim, ConstableBento took a crack at a motion-centric Ultra Street Fighter IV control scheme that -- among other things -- replaces the joystick with movement of the controller, and it looks pretty fun. It actually seems decently functional too, albeit probably not for high-level play.
Pulling off ultras by frantically flailing in a sort of tornado motion? Sure, I'm on board. I also really dig the idea of physically enacting the classic hadouken directional button combo for some reason. What a time to be alive, this here two-thousand-and-fifteen ayy-deeh.
You can grab the control scheme here, if you want to try it yourself. I can't wait to see this become a new way of adding insult to injury in high stakes matches. "I don't need an arcade stick to trounce this loser. I'll beat them down ... with motion controls."
