A Similar version was released by CGL as Earth Invaders in Europe (and also by Gakken as Heiankyo Alien in Japan), but they do have significant game play variations which make them a lot harder to play (see the pages for those games for a more detailed description).
Do I have this? Yes, with box. (This is mine pictured)
