Players fire phasers at the enemy space ships given each's firing strength, and the defending ship can choose to defend some of the blasts or none of them or all of the blasts of the attacking vessel with shield power.To win the game destroy the other player's Home Planet. Pieces move and fire very similar to chess pieces. However, multiple attacks can occur on enemy ships at the same time and you may destroy more than one ship per 'move'.Contains: Color gameboard, 32 space ship markers, rules. - BoardGameGeek
