Art of Fighting 2 (龍虎の拳2, Ryūko no Ken 2) was released in 1994. The second installment in the AoF series added the "rage gauge"; similar to the "spirit system" of its predecessor, it limited the use and effectiveness of special attacks. This game is also notorious for its difficulty with it being referred in many fighting circles as having some of the toughest opponent A.I. in a fighting game at the time. __TOC__
