Here you have the task of single-handedly defending your island from landing parties of enemy ships. The display on screen shows the coastline and your gun, which is strategically placed near the bottom in a bay.

The invasion force appears, one at a time, to the left of the screen and travel horizontally towards the shore.

Using keyboard controls to move and fire, your gun is placed so as to blast each ship as it passes. When one is hit, however, it leaves a shipwreck which forms a barrier to any further gunfire.

As the game progresses and more ships are destroyed direct hits become increasingly difficult. Should a ship land on your island the width of the bay in which your gun is placed becomes narrower. The game ends when either you accidentally crash into the bay or complete invasion is accomplished.

A simple yet enjoyable game, well crash-proofed and with some pleasing graphics, but it is one which you can never actually win.

The only goal is to achieve the highest score possible before you are ultimately stopped. Some comment on your performance at the end of each run might well make this more motivating.
