INTELLIVISION Sub Hunt

Game with box, manual, and overlays.

You control 4 submarines, one at a time. Your targets: 6 convoys, which are crossing the open sea. Navigate them, sight ships through the periscope, then fire your ready torpedoes. Take evasive action to escape hits from deck guns and depth charges. Sink the ships before they can reach a safe harbor and form an almost-unstoppable invasion force to attack your home base.
