Well, you know it's going to happen...one day. Many people out there still don't know zombies will attack us one day so we need to be prepared. Post your zombie plans along with some pictures or even tactics!
Remember, zombies can not climb because the muscle tissue dies after each strain. That means you can stay in a 5 story building, destroy the elevators, destroy the stairs, and you'll survive.
But....zombies can not feel pain. That means every bullet that goes towards him will not stop him unless it is towards the brain. Keeping this in mind, rifles are your best weapon. If you must use SMGs or Assault Rifles, keep them in single fire mode.
M16's are not the best weapon, they jam too easily, and the sights need to be adjusted every time. A jam is that LAST thing you need in a combat.
I recommend the AK 47 if you are using an AR
Other than that, an M1 Garand would be the best to fend off zombies.
Swords work as well, for they don't run on ammo and a single swipe of the head is all it needs.
Some Tactics:
In case of emergency, USE A BIKE
Wear tight clothes and cut your hair to be short. Otherwise zombies can grab it.
In a 4 man squad, have 2 people be the bait, and 2 snipers.
Stay in high ground, and destroy the stairs.
