King of Fighters is a fighting game series that is rather popular in its place of birth, Japan. Also rather popular in Japan are arcade shooters, labeled in the sub-genre as “Bullet Hell”. Well, it was only natural that a King of Fighters arcade shooter be created.
Apparently, the ESRB has evaluated an Xbox Live version of KOF Sky Stage, meaning that it will most likely be making its way to North America soon. It should be noted that KOF Sky Stage was released in Japan as a part of a larger game for the PSP, but I doubt anyone will have hard feelings about getting less KOF arcade shooter.
