how do we fight a zombie population
the scientists who started the outbreak in the first place scrambled for a way to make things right. how could they fight so many zombies on a large scale? well, you build assassin robots of course.
building the robots was easy, controlling them, less so. first they tried remote control, but it was too clumsy, and they had too few scientists to run the robots. so they tried automation. but the robots, however cleverly designed, had trouble discerning the healthy humans from the infected ones. they needed something to identify one from the other, but everything they tried did not work.
