This game plunges you deep into the underwater world. You control a bold adventurer, who is looking for the sea treasures. You have a sea vessel and a bathyscaphe that you can use to procure gold, gems and pearls. The evil monsters will endanger your adventure. Giant crabs, killer-squids, sharks, piranhas - these are just some of the monsters that you will face in the deep. Each monster has its own habits and specific behavior. Piranhas will try to bite you, sharks will gnaw the bathyscaphe's chains, squids will obscure your sight with clouds of blue ink, crabs will creep on the sea bottom. All this is accompanied with impressive tunes.
