An Arcade-Style, Old School Beat 'em up for PSP!  Forget everything your parents told you about violence only being a last resort. In Hammerin' Hero, if it moves, hammer it. Pummel your way through 12 arcade-style, old school beat 'em up stages, including city streets, an amusement park, a TV studio, a baseball stadium, and more. Ever wonder what happens if you hammer something over the head in deep space? Underwater? The only way to find out is with a copy of Hammerin' Hero for PSP system. This is one hero you don't want to mess with! (hint: because he has a hammer.)
