Crash Dive - Atari - Simulation, Strategy

The object of this game is to use your flying sub, the Sea Hunter, to destroy enemies and get treasures. You move fastest when in the air, half speed when in the water and cannot move forward when on the sea bottom. Your enemies and their point values are: Plane = 300 Helicopter = 100 Bird = 0 Boat = 50 Sting Ray = 20 Shark = 100 Angler Fish = 200 Squid = 100 Lobster = 25 You get 1 point for stunning the sea monster but cannot kill him. You cannot do anything with mines but avoid them. The possible treasures and their point values are: Sword = 200 Wine Bottle = 400 Sunken Boat = 500 Crown = 1000 Chalice = 2000 Pot of Gold = 3000 Key = 5000 You just play until you crash your sub or run out of fuel. You refuel by docking with the sub at the top of the sea (looks like a boat without a gun) called Sea View.
