What's the single most significant update in Power Stone 2? Four-player simultaneous fighting combat (which can be either human or computer controlled). The original game had some of the most frenzied and intense action between two players. Now with a total of four opponents, be prepared for some of the craziest and chaotic fighting action to ever hit a console system. Not only do you have to keep track of how many Power Stones you have in your possession, but you also have to worry about who's got the other ones that may give you the crucial "Power Drive" and "Fusion" attacking advantage. Also, on top of the original eight playable characters making returns, there are also four new regulars as well as two new boss characters. One of the new characters featured in this screenshot is a little chap named Pete who can transform into an toy-like robot.
