You're far out at sea, down the way where sunsets turn the ocean top into a kaleidoscope of colors. And, you've discovered the greatest sunken treasure of the Western Hemisphere.
But things don't sit right just yet. Your band of divers, laden with gold, haven't returned. Hearty lads though they are, they've been down too long--a little fishy it seems. But you cruise below and take a look-see for yourself.
EGADS! A little fishy? Battle stations! Prepare to take on divers. Killer sharks are nipping at their toes, and a nasty gang of scavenger subs is after their treasure!
So, batten down the hatches. Man the torpedo tubes. Watch your oxygen supply. And, whatever you do, don't let those pirate subs steal away your gold.
