Plague

You control a ship at the bottom of the screen whose object is to kill the three rows of insects that move horizontally across the top of the screen. Stopping you from getting to the insects are eight ships arranged in groups of four, as well as four heat-seekers that follow you whenever you go. Furthermore, the insects are capable of defending themselves by throwing bombs down at you, so you need to be careful not to hover below any of them. If you come into contact with any ships, heat-seekers, or insects, you will lose a life. Lose all your lives, and it is game over.
