The board contains some hidden electronics which when two adjacent spaces are pressed will either cause the 'Core Master' to light up and make noise - or not. Players move around the board and attack each other whenever they get next to another player by pressing down on both figures. If the 'Core Master' goes off, then the defending player is removed from the board. Game continues until all but one player is wiped out. The surface of the board can rotate to a number of different positions so that the pattern of which spaces are active and which are not can be changed between games. - BoardGameGeek
