The best psp game for blood, and it also has a lot of gameplay modes and a new mode which is really fun to play.
Oh and it has the best graphics that i seen for the psp, the sound is great too but you can tell that some of it was copy off the the ps2 and gamecube sound but besides that the gameplay is fun too, and with all the fighter to chose from and game modes to chose from, it is the best MK game for a portable system.
