Street Fighter EX2 (ストリートファイターEX2, Sutorīto Faitā EX Tsū) is a 2D head-to-head fighting game with 3D graphics co-produced by Capcom and Arika and originally released in 1998 as a coin-operated arcade game for the Sony ZN-2 hardware. It is the sequel to the original Street Fighter EX, a 3D spin-off of the Street Fighter series. An updated version of the game titled Street Fighter EX2 Plus was released in 1999 in arcades as well and subsequently ported to the PlayStation the same year.
The original version of Street Fighter EX2 retains all of the features from the previous game, Street Fighter EX Plus, including original features such as "Guard Breaks" (unique moves which cannot be blocked by an opponent) and "Super Canceling" (the ability to cancel a Super Combo into another Super Combo).
The primary new feature in the game are "Excel Combos", ("excel" being an abbreviation for "extra cancel"). Much like the "Custom Combos" featured in the Street Fighter Alpha series.
