An arcade game in which your task is to sink supply ships moving from left to right across the top of the screen.

To do this, you must first manoeuvre your gun under the ship before firing. The computer keeps count of how many ships you sink and how many escape.

Because the game is written in TI Basic, play is very uneven - for example, all movement stops while your bullet moves up the screen.

The limitations of the programming language mean that the game inevitably lacks excitement, though it is well written and well error-trapped.
