This was the original Graf Zeppelin. In this version, the plane has 6 types of weapons (only the bombs and missiles will do damage), shields and hull energy (shields can recharge and absorb projectiles), a radar, and the graphics are all in a pixel-art style. There was also space for dialouge. Originally, characters were going to be able to talk to you, sort of like in Star Fox.
