Ork is a platform game with five levels. It takes place on an alien planet called Cisskei, where the player character, an alien called Ku-Kabul, must find his way through each level in turn. The levels are filled with puzzles to solve and enemies to kill. Ku-Kabul is equipped with a machine gun and a jetpack. However, these must be used with care, because ammunition and fuel come in a finite supply, although replenishments can be found in some places.
