Tau Ceti is a two-player simulation of tactical future warfare on an alien planet. Powered by Matter-Energy Converters, military units of the opposing Kraa and H'ren forces expend Energy Points to move, attack and defend. Ten Scenarios provide a variety of combat simulations to be resolved. To win, each player must achieve specified objectives within a given time limit, measured in Game Turns. Each Game Turn represents 1-2 minutes of real time. On the map, each hex is 200 meters in diameter, and each Altitude Level or Terrain Level is 100 meters high.' - BoardGameGeek
