You've never seen Genji like this. Louis, a 24-year-old game developer in Texas, recently rigged up a sword-shaped Wiimote to control Genji's sword in Overwatch.
Using Bluetooth, Louis connected his Wiimote to his PC. A program called Touchmote lets him use his Wiimote like a PC mouse and, "with a little computer science magic (and extra help from the JoytoKey app)," he says, "I was able to start slashing at my enemies." It works like this, he told me over email:
Wii-mote A Button + "Stab motion" = shift button (Genji's Dash)
Wii-mote B button + "Slash motion" = Left Click (makes it feel like you're really slashing people with your Ultimate)
Wii-mote D-Pad = Camera Movement
Nunchuck = Movement and Jumping
Nunchuck + Wii Motion = E button (Genji's deflect)
Wii-mote "2" button = Q (Ult)
In the past, Louis says he beat Dark Souls 3 using his DDR dance pads. We were unable to corroborate this, but videos of him trying are sick.
