Difficulty Scaler - Progressive Wave Scaling

Difficulty Scaler - Progressive Wave Scaling

A comprehensive, standalone difficulty adjustment mutator for Killing Floor 2. Zeds get progressively stronger as waves advance - making games harder without spawning more Zeds.

Perfect for servers where you can't increase Zed count (performance limits, small maps, limited spawn volumes) but still want a real challenge at higher waves.

Features

6 Scalable Stat Categories - each with independent per-wave scaling, maximum caps, and per-group toggles:

• Speed - GroundSpeed + SprintSpeed
• Health - Body health
• Head Health - Gore/head health
• Damage Output - Zed damage dealt to players
• Damage Resistance - Reduced damage taken by Zeds
• Body Scale - Physical size of Zeds

Per-Group Toggles - Each stat can independently affect:

• Trash (Clots, Crawlers, Stalkers, Gorefasts, etc.)
• Large (Scrakes, Fleshpounds, Quarter Pounds)
• Bosses (all boss types - off by default)

Additional Systems:

• Force Sprint - Make Zeds sprint from a configurable wave onward
• Player Count Scaling - More players = stronger scaling
• Map Overrides - Per-map difficulty multipliers
• Named Presets - Switch difficulty profiles on the fly
• Live Admin Commands - Change any setting without restarting

Configuration

Scaling Formula:

Multiplier = Base + (PerWave * max(0, CurrentWave - StartWave))
Multiplier = 1.0 + (Multiplier - 1.0) * MapMultiplier
Multiplier = clamp(Multiplier, 0.1, Max)

Map Overrides - Add entries to scale difficulty per map:

MapOverrides=KF-BioticsLab,1.3
MapOverrides=KF-Farmhouse,0.8

A value of 1.3 means 30% MORE bonus scaling on that map. 0.8 means 20% LESS.

Custom Presets - Add your own presets:

Presets=MyPreset,0.03,2.5,0.04,4.0,0.03,3.0,0.02,2.5,0.015,1.8,0.0,1.0

Format: Name,SpeedPW,SpeedMax,HealthPW,HealthMax,HeadPW,HeadMax,DmgPW,DmgMax,ResPW,ResMax,ScalePW,ScaleMax

Compatibility

• Works with any game mode (Survival, Endless, Objective, custom)
• Works with any other mutator (Zedternal, Controlled Difficulty, etc.)
• Works with custom Zeds from other mods
• Stacks on top of existing difficulty settings - does not replace them
• No dependencies - fully standalone
