Sea Fighter Poseidon — About this game
Sea Fighter Poseidon makes its underwater scooter useful and dangerous at the same time. It carries the diver through the rescue mission, but enemy shots, obstacles or an empty fuel supply can make the vehicle explode. Abandoning it avoids that damage at the cost of greater vulnerability. Enemy scooters can also be destroyed in an explosion, while rescuing every companion in the area completes the stage.
