Space Invaders: The Original Game^[a] is a 1994 fixed shooter video game developed and published for the Super Famicom in Japan by Taito. Several ports were released for other platforms, including the Sega Saturn and PC Engine CD. The player assumes control of a laser base that must fend off waves of incoming enemies, who march down in formation towards the bottom of the screen. It is the fifth entry in the long-running Space Invaders series, and the second game to be produced for a home platform following the PC Engine remake Fukkatsu no Hi.

The Original Game serves as an updated version of Space Invaders DX, released a year prior for arcades, lacking the “Parody Mode” featured in the latter. The Sega Saturn and PlayStation versions add several new features, such as an arranged soundtrack and a new “Kawaii Mode” featuring more cutesy, cartoonish backdrops. It was produced by Keisuke Kasigawa and composed by Katsuhisa Ishikawa, with Space Invaders creator Tomohiro Nishikado being credited for the original versions. The Original Game was met with a mixed response from critics, most of which felt the game’s price point was too high with its large lack of content. It was followed by Space Invaders ‘95 in 1995.
