- The Game -
As the submarine captain, you must destroy all ten
of the merchant ships in the top row before you can
move on to your next mission. Try not to torpedo
hospital ships. It's a violation of international law--and
the consequences can be pretty immediate.
Skilful manoeuvring will be necessary on advanced
missions in order to survive exploding depth
charges, hostile torpedo fire, and magnetic mines.

Your sub has a limited supply of fuel and torpedoes,
and must be resupplied frequently. A supply sub will
pass by occasionally near the ocean bottom and release
a trained dolphin carrying fuel and torpedoes. By making
contact with the dolphin's supply pack, you can resupply
your vessel. Whatever you do, don't torpedo the dolphin!
He has many friends in these waters, and they won't
take too kindly to it.
