KOF: Sky Stage

(Online Interactions Not Rated by the ESRB) This "Real Martial
Arts" shooting game takes to the blue skies as six of your
favorite "The King of Fighters" main characters fight to stave off
the resurrection of Orochi. Each character retains their own
normal shots, as well as ultimate techniques. Each character's
special move has 3 three levels at which they can be unleashed,
depending on the amount of energy in your ultimate technique
gauge. The biggest feature of this game is its brand new fusion
of the play systems of the "Shooting" and "Martial Arts" genres.
