Yeah, not so much anymore. DayZ Mod 1.8.9 changed the zombie code and I can’t get them walking just some of the time now.
OK, so the Zombies walk SOME of the time now. WTF?! Why the change? It just got too easy to predict Zombie behavior so I’ve given them a little pep in their step around 20% of the time. The zombies are constantly evaluating whether or not to start a chase based on nearby players. 20% of the time you’ll see a burst of speed while they try to catch you. This will add some danger in tight spots and while camping since you can’t look at the zombies and count on the amount of time it will take them to walk over to you.
Overall, I’d still say the zombies are not your biggest problem.
