Sango Fighter (????) is a fighting game for DOS made by the Taiwanese Panda Entertainment and released in 1993. Set in the Three Kingdoms period of Chinese history, it is very similar to Street Fighter and Samurai Shodown, but with historical context. Shareware developer and publisher Apogee Software was planning on licensing and releasing the game in the United States under the title Violent Vengeance, but the plans for the deal fell through. Instead, the game was distributed in English under its original title by a Taiwanese company named Ascend, albeit without official permission from Panda Entertainment. Sango Fighter drew much attention of PC gamers when was released, offering the first fighting game with great graphics for that time and became the definitive fighting game for DOS.
