U can remove zombie sprint with special config options, sadly not rage modeI play games to relax and have fun. I don't like the fact that zombies still go into rage mode and sprint at you after damaging them. Zombies should never run. They are walking decaying corpses. We need an option to disable zombie rage mode and all sprinting.
Chance of rage is determined by difficulty level, so setting it low means you'll see less raging.
I'm pretty sure at lowest setting they never rage.
