The King of Fighters 2002 is the ninth game in the King of Fighters series and the second and last King of Fighters game developed by Eolith. The game is a "dream match" game in the vein of The King of Fighters '98, and is not part of The King of Fighters series' storyline.

The game brings back the team play composed by three characters each that was a tradition in previous games. The game brings also several important changes in the gameplay, like the "Free Cancel System" or "Max Mode System", the "Quick Emergency Evasion" and "Quick MAX Mode Activation", aside from the countless changes in each character's special moves and their properties. Here's a list of unlockable fighters you can play with:
