Street Fighter II: The World Warrior is a 1991 fighting game developed and published by Capcom for arcades. It is the second installment in the Street Fighter series and the sequel to 1987's Street Fighter. Designed by Yoshiki Okamoto and Akira Yasuda, who had previously worked on the game Final Fight, it is the fourteenth game to use Capcom's CP System arcade system board. Street Fighter II vastly improved many of the concepts introduced in the first game, including the use of special command-based moves, a combo system, a six-button configuration, and a wider selection of playable characters
