No one knows how or where it started. No warnings, no origin, no cause. It was as if they just appeared. Every major city in the world suddenly overrun. The streets littered with corpses, and those were the lucky ones. The others became those things. Mindless monsters craving blood and meat. Zombies. The world has been overrun by zombies. Survivors are few and spread out. There is no end in sight and no way of knowing if a cure can be found. All anyone can do is try to survive. This is the story of our struggle to survive.
