The object is to manoeuvre your fleet inwards to land where you will continue with tanks to destroy the mighty cannon Kuhn-Lin. On your way, you must go through six sequences of attacks/strategies.
The first is an aerial reconnaissance in which you see a map. You must decide how you will start the game. You may go into direct battle or use the secret passage and take the enemy off guard.
The hidden passage has you guiding your ship past mines while avoiding missiles. This screen is quite hard but makes the next section easier.
Sequence three is in 3D. You must shoot enemy aircraft and in the following level attack battleships. A report is given after each shot.
Screen five is Beach Head. For each ship you have left you get two battletanks. These tanks must travel through the defence system before blowing up Kuhn-Lin on screen six. The instructions state you need a few tanks to succeed.
The game loads perfectly and makes very good use of your computer's graphics and sound abilities.
