Stone Protectors is a an action game where each character has different weapons, all from melée to long-range weapons such as bazookas and guns. A kingdom built by crystals is under attack by the Saurians. Their leader, called Zok, wants the kingdom's powerful crystals which are protected by the Queen. Breaking into the castle, all seems lost, but as Zok reaches to take the crystal, it explodes into pieces and they fly away to Earth. All but one of the crystals reaches New York and falls into the hands of a rock band, who are transformed into goblins by the power of the crystals. Now their goal is to bring back the pieces to the kingdom and fight Zok and take his piece.
