Killing Floor 3: Onslaught Update - Is Now Live!

Version: 1.0.0.16

Release Date: June 16th, 2026

New Additions & Highlights

Welcome to the Onslaught... Update, a smaller mid-season update that adds the new level, Onslaught, and features a few Quality of Life improvements.

New Map: Onslaught

Horzine leveraged the sewer outbreak in Umezu to train personnel. Needless to say, it didn't go well. Littered with traps, this location becomes all the more dangerous as time goes on. Use as they did, to polish your skills. Space is a luxury here, and retreat is not an option.

Bug Fixes, Polish & System Improvements

Stability & Performance

• Fixed a crash that could happen while inspecting your character

• Reduced ticking dependencies for skeletal mesh components.

• Updated default configs to better understand the users system memory

• Updated Precompiled Shader Caching methodology to reduce in-game hitches on certain events

Quality Of Life Improvements

• Tutorial can now be Skipped for new players

• Single player games no longer require a ready-wait before traveling out of the HUB

• Single players entering matchmaking no longer require a ready-wait before matchmaking will begin

• Multiplayer games will skip the ready-wait before matchmaking if all players vote to go

• Players will now respawn in place when changing perks in the Hub

Bugs

• Fixed boss health UI drastically dropping during play — clients no longer mis-predict core boss damage

• Fixed the Trader Trail not leading to a Trader Pod during Trader Time, and a stale Trader Time timer preventing Ping Trader after skipping trader time

• Fixed some crafting dailies and weeklies not granting specialist XP
