1. Prepare for Mutants
If we have learned anything from the likes of video games like Fallout 3, Left 4 Dead, and Rage, it's that the future post-apocalypse will be crawling with mutants -- and not the cool kind of mutants that can shoot lasers out of their eyes.
We aren't quite sure why, but whatever the apocalypse brings -- nuclear disaster, disease, financial collapse -- there will always be mutants. And they will always be trying to kill you.
Pro tip: Learn to defend yourself, and we aren't talking about taking Karate lessons.
Just like your junior high soccer coach told you, except there's more at stake than a little plastic trophy and a pizza party.
Start developing those trust based relationships now, because you know what they say about relationships that are established in stressful situations -- they get you eaten by zombies.
Pro tip: Think: "I don't have to outrun the bear, I just have to outrun you" ... and repeat.
3. Pack Heat.
They gave everyone a gun in Gears of War 3, and you can't walk ten steps without coming across a machine gun in Left 4 Dead. It's just a fact of life, learn to use a gun.
Pro tip: If you need more convincing as to why this lesson is so important, see lesson one.
4. Necessity is the Mother of Invention
There is going to be a lot of stuff left over after the world ends. Most of it will be junk or unusable junk. But if you are industrious, you can turn that junk into useful and deadly contraptions.
Pro tip: You don't have to just make weapons. We're sure there are plenty of non weaponized contraptions that are also useful. But, you know, lesson one.
