How do I change zombie spawn rates in Project Zomboid?

You can customize the zombie spawn rates in Project Zomboid to be significantly higher - or lower than the base game, meaning that you can customize the experience on your server to fit exactly what you’d like. Here’s how you can adjust zombie rates.

  1. Go to the AleForge Panel
  2. Stop your server
  3. Open Startup and note down Internal Save Name as you’ll need this later

  1. Go to Files
  2. Open .cache/Server/
  3. Open InternalSaveName_SandBoxVars.lua

By default, this file is called dedicated_SandboxVars.lua

  1. Use CTRL+F to locate Population Modifier on line 591 and change it to your desired value. This value is a multiplier so a higher value will result in more spawns

Note the minimum and maximum values of 0.00 and 4.00

  1. Click Save Content and start your server
