KOF Skystage has finally been given a release date for XBLA, it will be released on the 15th Sept priced at 800MS points. Check out the full details on SNKP's official site.
For those PSP owners out there, this game is also included on Neo Geo Heroes: Ultimate Shooting. (Though i think NGH:US's main game is alot better than KOF:SS)
Now they just need to hurry up and release KOF02UM on XBLA!!
