In the mission First Defender you again have to meet with zombies. They are everywhere, most of the population mowed down this terrible epidemic brought from space. A few months ago an unknown object arrived on Earth. He was immediately taken into circulation by scientists, trying to figure out what's what. Opening the sealed capsule, they, not knowing about that, released the virus and were the first victims themselves. People are rapidly turning into living dead and there is no any cure for this. But not everyone is prone to infection. Find weapons and destroy undead.
