Titanic: A Mysterious Undersea Adventure is a puzzle arcade game for the PC made by Dosch Design.
Having virtually nothing whatsoever to do with the eponymous ship (it never appears in the game!), apparently recent scientific observations near the wreck have revealed the presence of a mysterious undersea village which may have special mystical powers. Discovering an amulet nearby, you dive down to the village to uncover its secret and find out if it played a part in the sinking of the Titanic.
When this game came out in 1998 it recieved mostly negative reception with a 25\100 from Absolute Games and a 32 out of 100 from PC Player Germany.
