However, investigations into the damage uncover that what hit the moon was not a comet, but a gigantic mother ship. Power up your ship, destroy enemies and fight your way through the bosses in an attempt to reach the moon's core and protect Earth from alien invasion. Enjoy the unique world of Dead Moon, including various stages with beautiful backgrounds, a power-up system that increases your attack as well as your defense and bosses that have you altering your ship's direction to fight them.
