I thought i saw a while back a plug in for Murderers/zombies. I believe it had a halloween type name for plug in lol.. The only one we've found is one where u change the scientist into zombies. But they do not attack.. My other server is owned by my brother and he had zombies everywhere... But I dont remember what the plug in was called. If anyone could help me to that plug in for zombies/murderers i'd appreciate it.. Thank you in advance...

maybe add server variables :
zombie.population : x
halloween.enabled = true
halloween.murdererpopulation : X
with x as desired population per square km

Thanks!
