You walk into an abandoned mall. You see zombies everywhere. Many different types as well. Slow, fast, tough, weak, strong, even the more mutated ones. You hide, hoping they don't find you. You don't know all of the types of zombie but you know some. There's the ones already stated and the more mutated ones. Such as complete parasite, morphers, and an unknown type. There are much more that are unknown. Let's hope you don't encounter them. Be aware for blood red vines, or hands sticking out of the ground. Or even tiny parasitic spiders. You must survive.
