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. Steam post image
