Street Fighter Alpha 2, known as Street Fighter Zero 2 (ストリートファイターZERO 2) in Japan/Asia and South America, is a 1996 fighting game originally released for the CPS II arcade hardware by Capcom. The game is both a sequel and a remake to the previous year’s Street Fighter Alpha: Warriors’ Dreams, which is itself a prequel to the Street Fighter II series in terms of plot and setting. The game features a number of improvements over the original, such as new attacks, stages, endings, and gameplay features.

Street Fighter Alpha 2 retains most of the new features introduced in the original Street Fighter Alpha, such as the three-level Super Combo gauge, Alpha Counters, Air-Blocking, and Fall Breaking. The main new feature in the game is the inclusion of the Custom Combo system (Original Combo in Japan), which replaces the Chain Combos from the first Alpha.  If the Super Combo gauge is on Lv. 1 or above, the player can initiate a Custom Combo pressing two punch buttons and a kick or one punch button and two kicks. The player can then perform any series of basic and special moves to create a Custom Combo until the Timer Gauge at the bottom of the screen runs out. The characters Guy and Gen can still perform Chain Combos, but only to a limited extent. Additionally, each character now has two Alpha Counters instead of just one: one that can be performed with a kick button and another with a punch button.
