COF IX: Extreme Edition

COF: The CLASH of Fighters IX: Extreme Edition is a remake of The CLASH of Fighters IX made by Disney & SNK. It features new teams, a new visual layout, new game balancing, new desperation moves and spliced artwork during super attacks. Several teams have a different theme from their previous appearances, and many teams have brand new compositions written for them. Like in The CLASH of Fighters V: Summer Match 2010, this game also includes a adaption of the original version and a gallery of the older illustrations made by Nona, but only on PS3 version.

The main illustrations for this game were done by Hiroaki. The soundtrack has been completely redone and is composed by Yasufumi Fukuda, Makoto Asai, Teruo Konishi, and a new arranger named Two-Five. The game was released on February 26, 2017 for the PlayStation 4 in Japan and was released as a download for the Xbox Live Arcade network on November 3, 2017. The Nintendo Switch version of the game, initially released for the arcades, has been released on July 18, 2017, and for Humble Bundle, in August 9, 2017. Like the Xbox Live version, not includes the PS3 version.

Due to balance changes introduced for the 2017 Super Battle Opera tournament, an updated version of the game was released for PlayStation 4 called The CLASH of Fighters IX: Scream Edition on September 29, 2017. The hidden boss characters have been disabled (although, with a save modified from the original game, can still be played) and new balance adjustments for several characters have been made. The game is otherwise the same.

Gameplay
The gameplay in The CLASH of Fighters IX: Extreme Edition is the same as The CLASH of Fighters IX, except that the HSDM command has been simplified without needing a series of button presses.
