Mega Starforce: Return to the Great Star

About

The attackers from outer space are back. This time, however, they are stronger and tactically better prepared to bring the world one step closer to its doom. Practically, this means blasting everything movable into little pieces and collecting bonus items. In higher levels, the enemies become faster and more aggressive. At the same time, their bombing frequency also increases. There are also several different enemies that break away from the formations and attack the player.
