The Rumble Fish (ザ・ランブルフィッシュ?) is a 2D fighting game developed by Dimps and first published by Sammy for the Atomiswave arcade platform in 2004, and was later ported by Sega to the Sony PlayStation 2 on March 17, 2005. A sequel, The Rumble Fish 2, has since been developed.
The game takes place in the distant future during the 21st century. During the turn of the 21st century, a large-scale natural disaster tears through the eastern side of an unverified country, destroying its economical and political operations and taking a total of 158,000 lives. A prominent corporation in the series, called PROBE-NEXUS, moves its base of operations to the ruined east side and begins reconstructing the area. The rebuilt area flourishes again as it becomes a wealthy and busy city known as Zone Prime, which serves as the backdrop for many locales in the game.
In the underground of Zone Prime, PROBE-NEXUS also sponsors a tournament known as the Fight for Survival, or F.F.S., where fighters are gathered from the city's slums and compete for sport. The first Rumble Fish game follows the fifth F.F.S. tournament.
