The first sequel to Street Fighter Alpha picks up where the first game left off, adding Dhalsim and Zangief from the original Street Fighter II as well as several newcomers (including playable bosses from the first game), and further developing the core gameplay. In addition to the Super Combo system, Alpha Counters, Air Blocking and Fall Breaking of the original, it adds a Custom Combo system that allows players to expend Super Combo energy to create their own combos, as well as updated stages and backgrounds, other gameplay updates and additional balancing.
