Before the outbreak, the Survivor had another name, Slobodan Chovyek. Before the Plague, it was scientific technician. That seems like a lifetime ago. The Survivor has been infected with the Plague. Unlike most victims, his body seems to have some resistance to the alien disease, though; he is not fully immune. He wears a fully enclosed haz-suit to slow change even more in hopes of finding a cure. Until then, he is neither Humanity nor Plague able to work with both to find the cure.
