"Guile awaits any news about his commander Charlie, who was last sent on a recon mission to discover the whereabouts of M. Bison's secret Shadaloo hideout. When no word is heard from Charlie in over a month, Guile begins to plead for the chance to lead a rescue mission, but his superiors refuse.

Then word reaches Guile about an underground Street Fighting tournament being held, reportedly hosted by M. Bison himself. Guile sees this as the opportunity that he's been looking for, and arranges to enter the tournament as a way to investigate the whereabouts of his commander and best friend."
