You are a soldier called Trixy, sent on a mission to save the planet from evil forces that have invaded the city-state called Solaris. You will shoot down your enemies and avoid their attacks as much as possible. You have limited lives, so avoid damage on your part. You will play both roles, sometimes using your flying gear and sometimes in body attire.
