Street Fighter II′

Street Fighter II: Champion Edition, released as Street Fighter II Dash (stylized as Street Fighter II′ with a prime symbol) in Japan, is a 1992 fighting game developed and published by Capcom for arcades. It is the first of several updated versions of Street Fighter II: The World Warrior (1991), and part of the Street Fighter series. The main changes are the addition of the four grand masters (the final four computer-controlled opponents in the single-player mode) as playable characters and mirror matches. The fighting techniques of the eight main characters from the original game were further balanced for competitive play.
