hehe looks like someone found the script for the new zombies which are coming in 2015
I'm looking forward to playing with them as well! Just wondering how did you get the characters to do that? Is is possible to add a new character for example the "combat mutant" and then to simply change the script it uses from ai_soldier.lua to something else? Is that how you could do it?
EDIT: Just tried it.. changed the script to the melee one.. the character chases after you but won't cause any damage when close... just looks at you with a hard cold stare that might kill your feelings but not your overall health... Interesting none the less!
EDIT 2: It seems they do hurt you! Only a tiny bit though..
