Killer Instinct - Windows PC

Unfortunately the Windows version of KI doesn't have an option for 2 players to use the same keyboard, but you can play 1 player with the X-Arcade as a keyboard.

For 2 players you will need to use one these options to make the X-Arcade™ emulate an Xinput game controller.
