Well, most poisons work with the transfer of blood to the central organs. If the zombies are really "dead" as we call them, poison is usless. But I am goin to stick with the theory that zombies have shut down all "unessesary" vital organs- shut all off but the respitory, circulatory, nervous and muscular. Zombies only need enough air to feed the brain, and enough energy to move the muscles. The digestive system may be working, but I doubt it. Shoot a zombei in the lung may kill it, but a head shot it the only way to instantly dispatch it.
Okay, Im going to give my own worst possible weapon in a zombie attack. Landmines.
The idea seems ideal, plant your garden and then watch through your binoculars how every zed blows himself up.
But mines do not blow up a person, they take off a leg and seriously injure that person. Landmines create cripple zombies which are far harder to spot. But in all fairness I would go for any weapon other then an exposive one. With zombies you try to destroy the brain and explosives are simply not accurate enough.
I guess the worse kinda weapon would be no weapon, hand to hand combat would frighten me the most.
well no weapon would be better then using a prosthetic leg as a club... especially if its your own.
Flaming Arrows --- Great now you have a pile of flesh coming at you, ON FIRE!
Throwing Weapons (Knife's,Star's,Tomahawk,etc)--- You have now thrown your only weapon and missed! Good Luck!Bear Repellent/Mace --- "Get Back! I'll use this!" As you spray you see that the zed cannot, for it's eyes have gone missing, you are now dead.
Stun Gun --- You may be giving the undead some jolt's but not enough too restart it's heart or incapacitate it, you are now dead.
Discharging a Firearm sideways --- You pull your side arm out and hold it sideways and pull the trigger as fast as you can, when the smoke has cleared all you can see is teeth sinking into your flesh. (These same rules may apply with bump firing and dual wielding as well)
