Line of Defense: Tanks is a fast-paced game of color-matching warfare. It combines mechanics borrowed from traditional shoot ‘em ups with those of a puzzler. Shoot the waves of oncoming tanks with a shell of the appropriate color. Fail to match the colors and it’s an instant game-over for you! When the going gets tough, resort to drastic measures with one of the special purple bombs, which wreak havoc across the entire battlefield. It isn’t just the main line of tanks that are a problem, but the secondary ones, too: use your weapons to blast them away! Fire a shell using the buttons on the bottom of the screen
