Against my better judgement, I kept playing with the werewolf zombie clones save. Migrants arrived, but I resolved not to care, focusing only on my starting 7, still walled into their little wooden box. Outside said box, whatever mysterious force that caused the initial infection also got the migrants. In half a month they all transformed. The wave had included a married couple, and apparently the wife was pregnant. She gives birth to twins. When they all change back, the twins, who's natural form is the monster form, proceeded to kill the lot of them. Now there are lycanthropic zombie clones, living werewolves, zombie livestock, zombie wild animals, zombie migrants, and various zombie bits of dismembered migrants.
It would appear the zombie werewolf clones and the living ones are not hostile to each other, but they attack the other undead. Except when they turn back into human zombies, then the living werewolves attack them. This has increased the number of reanimated gibs many times over. The bits lopped off of them while in human form seem to remain human zombie bits, but when the fallen clones reanimate, they are still lycanthropic and regenerate when they change form.
I may be headed for FPS death soon. There are almost 100 units on my map and the game's only gone on for 4 months.
