Killing Floor 2 features a wide range of difficulties that change Zed behavior, spawn rates, and individual Zed damage. Whether you are running a friendly “Normal” server or a hardcore “Hell on Earth” (HoE) tactical environment, mastering the difficulty and wave length settings is essential for community retention.

​
1. Difficulty Levels

In your PCServer-KFGame.ini or via Startup Arguments, use the following numerical values for GameDifficulty:

​
2. Wave Length

Adjust how long a match lasts using the GameLength variable:
  • 0 (Short): 4 Waves + Boss
  • 1 (Medium): 7 Waves + Boss
  • 2 (Long): 10 Waves + Boss
While you can edit text files, we strongly recommend using the WebAdmin GUI.
  • In-Game Switching: You can vote for or force a difficulty change between matches without restarting the entire server. This allows you to scale the challenge based on the skill level of the players currently in your lobby.
