You start the game with three submarines.
Guide your submarine with the mouse pointer. Press the mouse
button to fire a torpedo upward toward the surface. Press
the keyboard space bar to fire a torpedo to the right. Since
it takes your crew some time to reload the torpedo tubes,
you are allowed a maximum of one torpedo at a time in each
direction.
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. Skillful maneuvering
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.
