Sub Hunt for the Intellivision. You're at the periscope of a Nautilus class nuclear submarine, the last line of defense between the enemy and the fleet. Enemy PT boats drone around seeking you out. Meanwhile, enemy destroyers constantly jockey for depth-bombing position. You must keep you head to control depth, speed, direction and torpedoes. You have simultaneous periscope and satellite horizon displays with compass readings to keep you afloat and the enemy at bay. If you do it, you should be immediately commissioned an Admiral in the U.S. Navy.
