This PC Engine port has several significant differences despite remaining especially faithful to the original arcade game. Two levels didn't make the final cut. The fifth level was omitted, so there's no large Moai-headed mothership to be found here and the underwater/icy penguin eight stage was also cut, along with the blowfish boss. However, the game features an exclusive introduction sequence and a special stage where mini Moai-motherships appear as a tribute to their missing mother.
