On the purely mechanical planet Mekannis, the possibilities of four competing empires are determined by powerful machines. Players take on the role of a leader who guides the fate of their empire with the help of their machine. Through gigantic gears, the machine is set in motion, determining which actions are available in each round. The actions chosen simultaneously by all players allow for attacks and defenses, as well as the salvaging, collecting, and exporting of resources to earn crucial victory points. With an extraordinary theme and fresh mechanics, Empire Engine transports players to a strange, fascinating world. With cleverly reduced materials and a compact packaging, it follows in the tradition of popular portable expert games. May it be revealed who has control over their machine.
