On a distant planet, covered almost entirely by water, there are 3 islands with food and fuel. Each player controls one of these islands as their home base. Each player builds her own navy by selecting from a wide variety of battle boats. The propellers on each battle boat push the boat forward in a straight line. You can use a combination of propellers to allow the boat to spin and change direction. The soldiers on each battle boat may shoot their gun straight ahead. Each gun has a shield protecting the soldier and the boat from being shot. You can only sink a battle boat by shooting it in a spot that is not covered by shields. Your goal is to outmaneuver your opponents and deliver the fatal shot to the home base of an opponent while also defending your home base from being attacked.
