If you happen to have a Japanese PlayStation 3 account with access to a little bit of yen, you're in for a treat: Rockman: Power Battle Fighters is now available as a PS2 Classic!
Originally published in 2004 in Japan, Power Battle Fighters is a compilation of the two arcade games Rockman: The Power Battle and Rockman 2: The Power Fighters. Exclusive to these PS2 ports, a new, but admittedly bare bones 1 on 1 versus mode. Here players can fight each other as Rockman, Blues, Forte or Duo with all of their special weapons readily unlocked. The ability to block and counter attack with a single button have been added for balance, too.
Rockman: Power Battle Fighters will set you back 1,234 yen. Thanks to Vhyper1985 for the tip!
