Hey Khaine,
first off thank you very much for that Mod, I'm a Romero/TWD fan and love your work. Anyway, I'm playing on 200 Zs, insane, 50 Wandering/6 h to keep the game challenging. Also without that fancy traps, robots and turrets stuff. But, I really would like to get rid of the feral and radiated Z's.
I'm not a coder but I can edit the XML files, if I know what has to be done. Would it be possible to replace the ferals and radiated with regular Zs with some easy XML editing?
