Lunatic Fringe

You are alone on patrol at the unexplored borders of the Interstellar Alliance's territory. It's a remote, forbidding region known as the Fringe. Suddenly you are attacked by a marauding band of aliens. They are a new and belligerent race, whose battle tactics defy belief. You are too far away for assistance to reach you. Can you repel the invasion single-handedly, or is it only a matter of time before the Interstellar Alliance falls at the hands of the Lunatics?
