I had trouble with this tape. It appeared to load successfully but whether I was just bad at playing it or whether there was a fault on my copy I don't know.
The game makes you the captain of the battleship Graf Spee in the Atlantic in 1940, and your task is to sink all the enemy shipping in the area.
First you are shown a map of the Atlantic with your position, and you have to locate the enemy ships; this I found almost impossible as they seemed to appear and disappear erratically.
Once you have come close to them, however (which I only managed by accident) you are then given a view of the horizon and you must seek out and destroy the enemy with guns or torpedoes; but beware, he is shooting at you too.
The intructions that come with the tape say that you are offered seven levels of difficulty, but at no time when I tried the game was I given such a choice!
Very little time was allowed for keying in an instruction, and the response to the keys seemed poor.
The instructions were not very helpful, and I found it irritating merely trying to make the game work.
