Coktel Vision, 1988
Based on the classic Jules Verne's novel of the same name, 20,000 Leagues takes you aboard the famous ship Abraham Lincoln for an adventure on (or should I say, "below") the high seas. Seek out the secret of the legendary leviathan as you attempt to solve puzzles that almost boggle the mind. Explore and discover the unseen underwater world aboard the Nautilus, the submarine navigated by Captain Nemo, while following the trail of the sea monster.
The enhanced graphics are quite good for the era. While the interface is a bit clumsy, the internal PC speaker supported sound is slightly better.
