Sub Hunt

The battle awaits.

You are the captain of an Axis submarine tasked to sink the most amount of Allied shipping tonnage before all hope is lost.  Using your vertical firing missiles, you must score multiple hits to sink various military vessels while avoiding the civilian ships sailing in the same waters.

The ships are not defenseless. Mines and depth charges fill the water, and you don't have all the time in the world either...you must hurry.  Surface to refill your air tanks, and capture any dropped cargo for bonuses.
