Boss! from Fair Play Labs hits PlayStation Vita via PSN today. This 2D beat'em up has you taking the role of a monster who is only interested in destroying kingdoms and eating princesses. Players get to design their own monster (or boss) who gets set loose on a kingdom to tear apart all the would-be heroes attempting to strike it down. Boss monsters have special powers and skills that can be customized by spending coins collected during their rampages. If you're interested, here's a trailer and some screens for Boss! to view below.
