Shoot, attack, and stave off the assault by defeating all the Invaders on the screen. After annihilating a battalion of Invaders and defeating the Boss, players move on to the next stage. But beware of different types of Invaders, each with their own unique abilities – it's "Game Over" if players lose all of their stock cannons!
