Sub Stalker (1990)

Sight enemy subs from your command post in your yellow submarine -- then blast away!

With Sub Stalker, this mode of warfare continues -- complete with powerful torpedoes! This game and your Apple are all you need to experience the thrill of victory -- or the agony of you-know-what!
