Oh, you're using AI like a stuff chucking ape.
"AI" stands for "Artificial Intelligence." I read this as "your zombies don't do anything they just sit there unresponsive." Which is not really the case because the zombies have provably superior pathfinding logic.
What you meant is "Survivor Bots." No, it doesn't have this, and I'm not adding it. If this is what your opinion hinges on all I can say is: get more friends.
You still don't understand my point, so it seems. I do like ZAPT, the infection is very fun and I've used it before. Don't get me wrong there. The thing with Rotondo's mod, is that the zombies are not quite as responsive. I'm not entirely sure how to explain this. You can get past them (Rotondo's) without being tracked if you are quick enough walking through, but with ZAPT, you cannot do this. The Zombies always sight you. If you can see them, they can see you just about one-hundred percent of the time. The director just doesn't suit my wants. I prefer the sort of dice-roll in Rotondo's.
But AI, I'm talking about the Mutalid and Dog plus a few cheap and quick edits I myself have made.
