Street Fighter Alpha 2, known as Street Fighter Zero 2 (ストリートファイターZERO2) in Japan, is a versus fighting game and a sequel to Street Fighter Alpha: Warriors' Dreams. It was released for the Sega Saturn (among other systems) in 1996 with the same features as its predecessor.
A revision of the game known as Street Fighter Alpha 2 Gold, Street Fighter Alpha 2 Prime in Europe and Street Fighter Zero 2 Dash (ストリートファイターZERO2′) in Japan, was created the following year as part of the compilation title Street Fighter Collection. Its main attraction was the inclusion of a secret character: Cammy (as she appeared in X-Men vs. Street Fighter), selectable only in the game's Versus and Training modes. This version was given a separate Japanese release the following year under the Satakore (Saturn Collection) label instead of the original.
Street Fighter Alpha 2 features all 13 characters from the original Street Fighter Alpha (with M. Bison, Akuma and Dan now serving as regular fighters), plus 5 additional fighters (Sakura, Gen, Rolento, Zangief and Dhalsim). Like in the first game, the final boss varies between fighter and there is also a secret rival character that will challenge your character once certain conditions has been met.
The Saturn version was the only console port at the time to feature Evil Ryu, EX Zangief and EX Dhalsim, the latter two being Zangief and Dhalsim with their move set from Street Fighter II': Champion Edition (meaning they can't air-block or use Super Combos and such), in addition to Original Chun-Li and Shin Akuma, who were in all the other console versions. Alpha 2 Gold features all these characters and adds EX versions of Ryu, Ken, Chun-Li, Sagat and M. Bison, as well as Cammy from X-Men vs. Street Fighter.

Having originally been released a month after the PlayStation version in Japan, the Saturn version includes additional features (namely an Illustrations menu and a corresponding new music track) despite both versions seeing a simultaneous release overseas. Mega Man 8, another Capcom title, would follow the same trend.
Due to hardware limitations, Survival Mode is cut from Alpha 2 in favor of Training Mode and Training Mode is cut from Alpha 2 Gold in favor of Survival Mode for the PlayStation versions. The respective Saturn versions incorporate both modes.
Alpha 2 Gold adds an Akuma Mode (Gouki Mode in Japan) where the player faces Shin Akuma (Shin Gouki) in a best of 3 match. For the Saturn version, this comes at the cost of its exclusive Illustrations feature.
