RTF is a global modification that replaces all towns in the game.

Yes, there's a mod for the undead that includes wolves made of skeletons, ghosts, dark knights, zombies, mummies, and vampires; werewolves are decent. I mean, keep the first two vampire upgrades, which are hard to counter, and make the third one werewolves with a transformation attack (random spell: either control or berserk).
