Nightfall News: Operation Deep Freeze Additions and QoL Improvements2026-03-11Hello everyone, As we work towards getting the Killing Floor 3: Operation Deep Freeze into your hands, we wanted to talk about some of the additions and quality of life improvements headed your way. First up, performance improvements. Operation Deep Freeze includes a focused performance pass targeting rendering stability, CPU overhead, animation cost, VFX load, and memory efficiency.

Nightfall News: Cold Steel Is Headed Your Way2026-03-05Nightfall, With our monitoring of the Antarctic Base well underway, the intelligence team has found more than just new mire creatures. They’ve been tracking what appears to be an increase in Zed lethality, akin to our records of older zed types. Oddly enough, this does seem to make them more vulnerable to most of your arsenal.We’ve made a sweeping combat balance pass aimed at making Killing Floor 3 feel faster, deadlier, and more in line with the pacing and lethality players remember from Killing Floor 2. Zed health has been reduced across the board to bring back that punchy, satisfying kill feel, while Zed damage and spawn rates have been in

They are encased in thick armor, yes, but drone fo
Nightfall News: An Antarctic Expedition2026-02-13Nightfall, Your next mission is just around the corner, and you’ll need to prepare for a frightening chill. We’ve found evidence that Dr. Moorcroft has taken his Mire experiments even further from scrutiny, to a well hidden and remote Antarctic Base. The good news is we’ve found it, located on the Brunt Ice Shelf.https://media.tripwirecdn.com/021326/abmesshall.pnghttps://media.tripwirecdn.com/021326/abtunnel.pngSatellite reconnaissance shows that this station is attached to a dig site, something you wouldn’t expect from a purely research facility. Could something frozen in time have drawn his interest here?https://media.tripwirecdn.com/021326
