Play Poseidon Wars 3-D (USA, Europe) Online

In Poseidon Wars 3-D, you have just entered the navy as a cadet and you must make your way up to Admiral. To do this, you must go out at sea with a submarine and destroy several enemy targets. Once you have defeated each enemy target, the mission is completed, and, upon completing some of them, your rank increases. Before defeating each target, however, you also need to destroy enemy jets, choppers, and submarines who will launch missiles or rockets at you. If you are hit by any of these, damage is inflicted to the submarine, but you can shoot down any of the missiles or rockets. You will need to keep an eye on the built-in radar and sonar to find out where enemies will hit next. Your fuel is limited, and can be increased by destroying certain enemies. The game ends when your submarine is destroyed or you run out of fuel.
