Swordfish™ is North America's first location-based fishing game designed for Java enabled mobile phones that are GPS equipped. The game system is comprised of three main components: the client software that resides on the phone, KnowledgeWhere's Location Application Platform (LAP), and the mobile providers' location-based system (LBS). Swordfish client software provides the gaming interface to the end-user. It is written in J2ME but can easily be converted to BREW.
