FEEL THE AMAZING POWER THAT RYU IS INSIDE OF HIM !!!!!!!!!!!!!!!!!!!!!
Street Fighter Alpha 3 features 3 selectable Super Combo gauges, called "ISMs", with each one having different usages and features.
X-ISM characters are based on their Super Street Fighter II Turbo counterparts. Their attacks cause more damage than usual, but they can't air-block or Alpha counter and have only one Super Combo.
A-ISM characters are based on their Street Fighter Alpha 2 Gold counterparts, with some changes to their moveset.
V-ISM characters often have all the moves they have in the other modes, and can use a heavily modified version of the Custom Combo system previously featured in Street Fighter Alpha 2, called Variable Combo. V-ISM characters can't use Super Combos.
Unlike it's prequels, this game is mostly based on attacking rater than positioning, mostly because the Special Moves were weakened while the normal moves were given more priority. Throws were made better as well.
Characters
As with the previous Alpha titles, several characters were added to the game: R. Mika, a female Japanese wrestler whose idol is Zangief, and Karin, Sakura's rival who was first introduced in the Masahiko Nakahira manga Sakura Ganbaru. Juni and Juli, who are basic sprite swaps of Cammy and M. Bison's personal bodyguards, were also introduced. They were boss characters in the 1-Player mode and were only playable through a code. Cody from Final Fight, who was transformed from a vigilante into an escaped convict, makes his Street Fighter debut.
Cammy, who was previously featured the console-exclusive Alpha 2 Gold, makes her official Alpha debut in the game along with several characters from Street Fighter II including E. Honda, Blanka, Vega and Balrog. As with Juni and Juli, Balrog is a boss character who is normally not selectable by default.
Unlike the first two games, M. Bison is the last boss of the game for every character except himself (in his case, Ryu serves as M. Bison's last boss). For this reason, a more powerful version of M. Bison (named Shin M. Bison in Japan or Super M. Bison in the US) appears in this game, who uses an overpowered Psycho Crusher.
