The planet is called Banshee. The air is unbreathable, the water poisonous. It is the home of the most implacable enemies that humanity, in all its interstellar expansion, has ever encountered. For the commando forces that are to be dropped on Banshee, special body armor has been devised, the culmination of ten thousand years of the armorers craft. A trooper in this armor is a one-man, atomic-powered battle fortress, but he will have to fight a nearly endless hoard of berserk, hard-shelled monsters, the fighting arm of a species that uses biological technology to design perfect, mindless, war minions. Felix is a scout on A-team Two. Highly competent, he is the sole survivor of mission after mission. Yet he is a man consumed by fear and hatred. He is protected not only by his custom-fitted body armor but also by an odd being which seems to live with him, a cold killing machine he calls the Engine.
