is an update of Fatal Fury 2 released in 1993 that added three characters (Tung Fu Rue, Duck King, Geese Howard) from the first Fatal Fury game (as well as Ryo Sakazaki from Art of Fighting) into the mix, in addition to making the non-playable CPU bosses into playable characters, totaling up to 16 characters. This game was one of the most popular games in Japan in 1993. It has been said that, as a result of the popularity that ensued from Ryo being a hidden character in this game, The King of Fighters as a series was born. This game was later ported to the Game Gear and SNES by Takara, to the Sega CD by Victor Interactive Studios/JVC Digital Studios, and to PC Engine CD by Hudson Soft. SNK Playmore released an Xbox 360 port on September 5, 2007 on Xbox Live Arcade.
