Re: Discussion: Taxonomy and Pathology of Halloween Monsters
I am currently running a zombie apocalypse campaign. The way that I am dealing with the disease which turns living humans into unliving mobile death machines, is by saying it is a parasite. It would not make much sense for a zombie to rip a person's throat out, killing them in 30 seconds, but somehow a virus takes hold in the brain and reanimates the body. A parasite can move under its own power, so it does not need the blood to be pumping to move throughout the body and take control of its dead host.
Separating the head from the body of these zombies will deny the parasite full control of the body, it might still twitch a bit now and again. The head will still function as it did while it was attached, so it will still be dangerous.
As far as vampires go, if I am not telling a masquerade game, then I like them to be like the 30 days of night vampires. Their bites will turn a human into a vamp, but they don't want that and destroy the body after they feed.
