This is what defines a Romero Zombie.
* Newly dead corpses reanimated by radiation, chemicals, viruses, sorcery or acts of God
* Human, although some depictions include zombie animals
* Very strong, but not very fast or agile
* Impervious to pain and able to function after sustaining extreme physical damage
* Invulnerable to injury, except for decapitation or destruction of the brain
* Relentlessly driven to kill and eat
* Afraid of fire and bright lights
If it's sorcery that caused the zombies, then I can develop an plan to find out who originally did the spells that summoned the zombies and caused the ZA.
Basically I would pass on the information that it was Voodoo or sorcery that caused it once I found out, to the other survivors out there. so that we could all pinpoint where the fucker held responsible for the whole Zombie out was at when it started.
Then if that stupid fucker was still alive, then I question him/her on how he/she did the spells, etc.... and then kill him/her. If the leader/summoner is dead then theoretically ALL zombies everywhere should drop dead if there is no longer somebody for them to follow.
But if they don't, then I'm going to use the information that I tortured out of the leader/summoner on how to stop the zombies, to make every single one literally drop dead.
Then just like that, the ZA would be over.
If it's radiation, chemicals, and or viruses..... well, that's a little bit tricky...but in the end I'd probably offer to try to guard the smart guys. you know, the scientists, doctors, etc who humanity would need to find a way to become immune to that kind of thing. I don't know about you, but I'd definitely want an zombie vaccine.
If it's acts of god, then well... we're all fucked no matter what we do!
