Whenever people make this sort of lists, they always forget about zombies. But depending on the type of zombie uprising we are dealing with, the undead may be the only thing you see.
It’s commonly accepted among zomboligists that there are three stages of zombie infestation. The first stage consists of one or two isolated cases, at most a small group. Shocking yes, and no doubt the existence of a reanimated corpse would change everything about the way we see the world. But as far as a threat, a Class I event is easily contained and no great threat to the majority of people.
The second stage of a zombie rising affects an area as large as a city. Much worse than a Class I infestation, thousands will die and whatever city is hit will be lost. But unless you live in the city affected, you’ll probably be OK during a Class II event and the military will eventually regain control.
Not so with a Class III event. Class III is the apocalypse. Class III is the end of the world. What are the chances you will survive? What are the chances you will even know what is happening before you come face to face with a zombie? And when that happens, what are you going to do? Probably get bit. And that’s the thing. Most people won’t survive the zombie apocalypse. No matter how well thought out your plan, you probably won’t even get to put it in place. Or something simple will throw you off. You’ll be on vacation. You won’t be able to get back to your apartment and pick up your weapons. Even if you do survive, you are going to see zombies. You are going to have to kill them. No one will survive the zombie apocalypse unscathed. In the end you’ll have to choose—beat um or join um.
