I'm working on my own server-side (XML only) version of a classic Romero-style zombie overhaul, and when I finish it I'll be posting it here on the forums. I'll try to remember this thread, but if I don't, and you see my modlet here, lmk and I'll be happy to just copy out the no-rage portion.
I actually intend to just tone the raging waaaaay down, because I like when they stumble and rush toward you unexpectedly, but it'll be more chill. If you want no rage at all it'll be simple enough to do that.
Nothing against Khaine's overhaul, I just want slightly different things. I use a few of Khaine's other mods and they are great, so it's worth checking out his Romero Mod.
Disclaimer: I have a life and ADHD so it'll be ?????? when I actually finish it
