Classic vs Mundane Zombies

What is the difference Between the world option and the mod?

As far as I know, the world option prevents ALL spawning of monsters except zombies and wildlife,the mod however, only prevents special zombies from spawning, not anything else.

The option tries to remove everything that doesn’t fit in a classic zombie film, which means stripping the game down to just towns, wilderness, and zombies. Mundane zombies just cuts out the weird zombies.

Does this include zombie scientists, fat zombies, zombie soldier / grenadiers etc from spawning too?

is that the list of nerfed zombies or the zombies that remain?

Removed zombies, all the names in the list are of special zombies.
Still you should double check the list in the game, after all, that list is 4 years old…
