Tsunkatse is a popular spectator sport in the Delta Quadrant invented by the Norcadians. In Tsunkatse, two contestants battle in an arena wearing polaron disruptors on their hands and feet, which deliver a bioplasmic charge on contact with the opponent’s two target sensors, located on the sternum and between the shoulder blades. The object is to attack the opponent’s sensors while defending your own. There are four types of Tsunkatse matches: blue, red, green, and yellow. The objectives of blue and red matches were to knock out and kill your opponent respectively; however, the objectives of green and yellow matches were unspecified.
