The new genetically engineered soldiers arrive on the garbage planet, and, since the world is listed as uninhabited, Colonel Mekum decides to use the colonists' community as the target in a training exercise. Just after Mace finds Todd, apologizes and invites him back, the soldiers spot Mace and kill him. Though out-manned and outgunned, Todd's years of battle experience and superior knowledge of the planet allow him to return to the colony and kill the advance squad. Nervous that an unknown enemy force may be confronting them, Colonel Mekum orders the soldiers to withdraw and return with heavy artillery. Using guerrilla tactics, Todd outmaneuvers and defeats all of the remaining soldiers, including Caine 607, whom he defeats in vicious hand-to-hand combat by clever tactics rather than mere physical prowess.
