Killing Floor 3: Zed Weaknesses and Damage Types

I’ve put together this handy chart for the weaknesses and strengths of Killing Floor 3 Zeds. You won’t have to dig through the codex anymore to find this info. Just a heads up, I don’t know the exact damage multipliers myself. This chart is really just a basic visual guide, sort of inspired by Pokémon type charts.

Killing Floor 3

Looking for a complete Killing Floor 3 weaknesses and resistances chart? This guide covers every Zed type, their vulnerabilities, and the most effective damage types to take them down. Whether you’re new to the game or a seasoned player, this resource will help you optimize your loadout and strategy.

The Chart

Green: More effective damage type
Red: Less effective damage type
White: Normal effectiveness

Sound-based weapons don’t have specific Zed weaknesses, but they excel at shattering armor on Scrakes, Fleshpounds, and Impalers. However, sound damage is less effective against flesh and tech components.

Husks and Sirens: Both have armored bodies but exposed heads. Sound damage works better on their bodies, but not on headshots. For Husks, aim for the fuel tank (tech weak point). For Sirens, go for the head (flesh). If using Overpressure rounds, hitting the body works well.
