Abstract: The present invention relates to a game operated through an application, installed on a mobile device, with the core rule set being managed on a centralized, computer server. The purpose of the game is for player Assassins to eliminate player Targets. The server contains algorithms which uses information provided by the mobile device, including, but not limited to, geo-location, device orientation, and user-selected virtual weapons and defense tools, to determine whether Assassins have successfully eliminated their Targets. Virtual weapons and defense tools may be acquired by players through credits earned, based on game scoring, or when purchased.
