The game is scenario driven and each scenario will define the goal of the game as well as initial board set-up. Each turn, players have a certain number of energy points that can be spent to perform actions, such as movement or fire. Combat is resolved by rolling special dice, a ten-sided die with letters and an eight-sided die with numbers. The resulting letter-number combination is compared to the target ship’s reference card to determine the result. Hits on a ship are indicated by placing colored pegs in the figure’s base.
