I think the idea of a special blend of zombies, or having the option, would add surprise and jump scares and give all zombies a bit more of a unique personality - even if its randomly generated. Each zombie on the map would have a randomly generated set of variables set to them from the drop-down list when editing zombies. Some will have bloodhound in terms of smell, while others would have normal or very weak smell - others would be fast shambles while a small group could be sprinters. (for lag/management reasons) I believe this would add variety, make scenes and encounters more dramatic, movie-feel, and more surprising as you won't really know WHAT you might encounter other than zombies afoot. I believe this is also easy and quick to implement since it's just randomizing the zombie's stats to create a mixed bag of different "unique" zombies. Tell me whatcha think, or just "like" this post. Even if it doesn't get added, would like to see if the community thinks its a good idea regardless.
