Based on the popular Capcom coin-op Super Puzzle Fighter this game combines the popular drop-and-stack play mechanic found in games such as Tetris Columns and Baku Baku with fighting characters from SF II Alpha and Darkstalkers. Ryu Ken Sakura Chun-Li Morrigan Felicia Lei-Lei and Donovan (with Akuma/Gouki Dan and Devilot as hidden characters) appear on-screen when an area has been cleared and start dukeing it out. One of the most unique entries in the electronic gaming pantheon.
