Having virtually nothing whatsoever to do with the eponymous ship (it never
appears in the game!), apparently recent scientific observations near the

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.
