Power Stone provides the fighting game genre with fully functional 3-D combat environments and frenzied strategy. Face your opponent in a London courtyard and you can hurl café chairs and tables at him before taking him out by swinging around a lamppost. Or fight in a dilapidated shopping mall, and beat your foe down with a giant stuffed teddy bear after tossing him through a storefront window. Each multilevel combat area is stocked with crates, barrels, clubs, even ray guns, and everything can be used as a weapon. Interactive fighting environments are fun, but what really sets Power Stone apart are the power stones. Collecting all three stones transforms the character into a superbeing, unlocking new and devastating attacks. Since the overall goal of the game is to beat up your opponent, and the superform lets you do the most damage, competition for the stones is fierce.
