MORTAR is a fast-paced one-button game. You are in charge of a mortar that constantly moves from side to side on its own. Your goal is to destroy the enemy tanks that are approaching you from the top. Hold a button to fire a bomb ahead and destroy all the enemies within the radius of its explosion. Or press a button to shoot the enemies with a small shot. You stop moving when you shoot or fire a bomb. The game is over when any enemy reaches the bottom of the screen.
