The world war is spreading across the seas! Aim at enemy ships and fighters!!
This game consists of four successive scenes: a battle between armadillos during the day; battle between armadillos at night; in combat between fighters and battleships by day; and battle between fighters and battleships at night. Each scene leads into the next as the previous scene clears. In scenes where battleships fight battleships, the scene will be clear only after you have destroyed a certain number of enemy ships. If MTBs appear on the screen, the scene will be clear when they are all gone. In scenes where fighters attack battleships, the scene will be clear after a certain number of fighters have appeared.
Each scene counts as one pattern, and the game's pattern number is displayed alternately with the score at the top right of the screen. During nighttime battles between battleships, you don't see the top row of enemy ships, but when a shell hits a ship and explodes, the screen will glow for four seconds and the ships will appear. The joystick is used to move the ship left and right while firing projectiles at enemy ships and planes. If you fire a projectile while your ship is moving, the projectile will go in the opposite direction to where the ship is going.
