A Mortal Kombat X themed controller was revealed at the GameStop Expo earlier this week. The controller is very minimalist in design missing a D-Pad and triggers. The bumper buttons are laid out next to the normal buttons to be more accessible when pulling off combos. The design itself is weird and sports an asymmetrical design with the right side curved off. The menu buttons are along the top of controller.
