Description taken from PlayStation 2 version of this game

Zapper is a 3D platform game starring a young golden cricket on a quest to rescue his brother from a merciless magpie queen. The game spans six outdoor worlds of trap-filled action, where players must avoid and react to quick-moving enemies and threats in order to stay alive. Collectibles in the form of "Z" coins are spread across the levels, as are an assortment of helpful power-ups. Developed by the same team responsible for Frogger 2: Swampy's Revenge, Zapper offers a separate battle mode supporting up to four players for simultaneous cricket-jumping action. ~ Scott Alan Marriott, All Game Guide
