My family considers me as the 'go-to' incase there is a zombie-esque apocalypse.
I'm not kidding.
Anyways I'll share my tips with you.
1. Cuss alot. It's just what you do when a Zombpocalypse strikes.
2. Have guns and aim for their heads. If they don't have heads, they can't bite you.
3. Medical supplies are essensial to survival.
4. Healthy food and fresh water keep your body in tip-top shape for running like hell and keeping yourself alert.
5. Have a vehicle so you can mow down the hordes.
6. Spray paint is useful for marking certain areas and if you can establish a code or easily understandable system of icons (X for 'do not go here', arrow for 'this way', teeth for 'stuffload of zombies', etc) this will be a very useful tool for communicating with other survivors.
7. Find a safe place of refuge if you are staying in one area for a long time; it's not good to stay in one place though because zombies can smell fear, hope and humans.
If you think I missed anything just let me know and I'll add it.
