I just added a new link, its a small set of "medieval" looking zeds i did for another project but someone may like to use them also in the regular game idk, anyway its there, in the first page, about 14 new zombies maybe cant recall.
I have only done the entityclasses xml so they can only be spawned using the menu, if someone makes the entity groups then they sould work fine as the other packs, they are additions, not replacements and they should work fine also with the other packs togheter.
