 The game was designed to use the Mega Drive's six-button controller, along with "Eternal Champions".Also like "Eternal Champions", "Cosmic Carnage" can be very difficult to compete against the CPU characters using the standard three button controller.With the six button controller, the player is given two buttons to kick, two buttons to punch and two to ‘provoke’ (taunt), with the ‘provoke’ attack differing depending on how fast one presses the button.
