Have been trying to remember a p.c. game from the late 80's.It had 7 c.ds. It was about an explorer, I think in the Arctic. When came upon a ship wreck. As he entered the ship he started having visions and ghosts started to appear. You then became this explorer. As you went thru the ship you had to explore all the rooms and try to figure out what the visions were about. you also had to figure out how to get into each room.The rooms had a 3 digit combination. In the end it turned out that the explorer was the son of the the ship's captain. ..................... Does this sound familiar to anyone?
