Super Street Fighter II Turbo
Super Street Fighter II Turbo, released in Japan as Super Street Fighter II X: Grand Master Challenge, is a competitive fighting game released by Capcom for arcades in 1994. It is the fifth part of the Street Fighter II subseries of Street Fighter games, after Super Street Fighter II: The New Challengers. Like its predecessor, it ran on CP System II hardware. Super Turbo introduced several new game mechanics that were not present in previous versions of Street Fighter II, including Super Combos and Air Combos. It also introduced the secret character Akuma, who would appear again and again in later Street Fighter versions and other fighting games from Capcom. Super Turbo was originally ported to the 3DO Interactive multiplayer, followed by the PlayStation and Sega Saturn (under the title Super Street Fighter II Turbo: The Ultimate Championship) as part of the Street Fighter Collection, and for the Dreamcast in Japan under the title Super Street Fighter II X for Matching Service. A remake of the game was released for the PlayStation 3 and Xbox 360 under the title Super Street Fighter II Turbo HD Remix.
