Cyber Knight II: Chikyū Teikoku no Yabō

After returning to Earth to find it being taken over by a military dictatorship, the crew is jailed but escape to be recruited into the resistance. They must travel the galaxy in their new spaceship, the Galvodirge, in order to help other human civilizations resist the attacks of the Earth's army. Like the first game, most of the planets are "dead" and serve no purpose in the game. Players even get to explore sewer systems, towns, and giant mazes.
