Ultra Street Fighter IV is an arcade fighting game developed and released by Capcom on August 7, 2014, and the final chapter in the Street Fighter IV line. Built on the same combat engine that revived the series, it pits a roster of world warriors — martial artists, assassins and wanderers — against one another in one-on-one bouts where timing, spacing and the perfect read of an opponent decide everything.

The game is remembered as the most complete version of Street Fighter IV: a larger cast, an expanded stage list, and the return of long-absent fighters to the lineup. New fighters join the veterans, and returning ones bring new tools, while the punishing focus-attack system and the comeback mechanic that turns a losing round around keep the pressure on until the final hit. Released for Microsoft Windows.
