River City Ransom, originally released as Downtown Nekketsu Story (ダウンタウン熱血物語, Dauntaun Nekketsu Monogatari?, lit. "Downtown Hot-Blooded story") in Japan and later as Street Gangs in PAL regions, is a video game for the Family Computer/NES. It was developed by Technōs Japan and originally released in Japan on April 25, 1989. It is the third game in Technos' Kunio-kun series released for the console, preceded by Renegade and Super Dodge Ball. Like its predecessors, River City Ransom underwent great changes in its storyline and graphical presentation during its localization in order to make the game more palatable in the western market. It was one of the first console games published by North American subsidiary American Technos. Remakes of the game have been released for the Sharp X68000, PC-Engine Super CD-ROM², and Game Boy Advance (GBA). The NES version was re-released on the Wii's Virtual Console in 2007. It was also released on the 3DS Virtual Console in the PAL Regions in July 25, 2013 and in North America in November 14, 2013.
