Street Fighter Zero 2 Alpha is the correct name?
Arcade
Street Fighter Alpha 2 was released under the title of
Street Fighter Zero 2 in Japan, Asia, and South America. The American and European versions of
Alpha 2 feature three additional characters who were not in the
Zero 2 version: Evil Ryu and the EX versions of Dhalsim and Zangief.These three characters were selected by Capcom USA.
Capcom released an updated version of Zero 2 titled Street Fighter Zero 2 Alpha, which features all the additional characters from Alpha 2, as well as other changes to the game. In addition to Zangief and Dhalsim,
Zero 2 Alpha also features EX versions of Ryu, Ken, Chun-Li, Sagat, and M. Bison, all of whom were characters from
Street Fighter II′: Champion Edition. Custom Combos are now executed by pressing a punch and kick button of the same strength simultaneously and now require half (1½ level) of the Super Combo gauge filled to perform them. Some of the characters have gained new moves such as Ryu's
Shakunetsu Hadouken and Dhalsim's Yoga Tempest.
Zero 2 Alpha also features a survival mode, as well as a 2-on-1 Dramatic Battle mode similar to the hidden "Ryu and Ken vs. Bison mode" in the original
Alpha. In the Japanese version of
Zero 2 Alpha, Evil Ryu has different dialogue exchanges and a different ending from his regular counterpart.
