Yuletide Horrors

  • Happy holidays from the Horzine team as we present our seasonal Yuletide Horrors update! Take a perilous stroll through Sanitarium and uncover its dark, ritualistic secrets while dispatching the holiday horrors skulking through its maniacal hallways. But don’t stop there! You can thwart the Patriarch’s plans to clone a legion of Zeds in the Biotics Lab Objective game mode. Seems a bit much to get done on top of decorating and gift wrapping? Don’t worry, the Horzine team developed a few new handy dandy weapons to knock the socks off those pesky, ravenous elves! As you deck the halls with guts and blood, wear some holiday cheer with our many new cosmetics that’ll put even your own grandmother’s sweater to shame! Tis the season to be slaying, and from the Horzine team, we wish you all a grand, bloody-good time!

Addressed Community Feedback
As mentioned in the 2018 Killing Floor 2 ‘State of the Game’ our goal is to bring to the community a continued stream of QOL changes for each update throughout the year. Please continue to report any QOL changes you believe should be added to the game by submitting your feedback in the ‘general’ section on our official forums at: https://forums.tripwireinteractive.com/forum/killing-floor-2


  • Zeds
    • Rioter
      • Head armor obliteration value increased from 80 to 125.

Designer Note :
There was a bug with the damage calculations where Perk bonuses were not applying correctly to the head armor obliteration value. As such, the base obliteration number was lower than intended. Now that the bug has been fixed, the value has been increased to its intended gameplay value.
