I have made a zombie addon which includes 12 types of zombies. Each zombie can only be immediately killed by a headshot. Would anyone like to host the WIP .pbo file?
Each zombie inherits from a civilian model, but has setdammage set to 0.8 on initialisation, for that "gore" look; however, the armor level of each zombie class was upped significantly so that the zombies wouldn't be killed with one shot.
I will post the addon's config.cpp in mission editing & scripting so that other zombie mission makers can use my code (e.g. perhaps Karillion, or D.Murphy man) and produce better works!
EDIT: Have just put source code in BREATHE section. Feel free to take a look.
