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 on our official forums at : https://forums.tripwireinteractive.com/forum/killing-floor-2

  • Zeds
    • Bosses
      • Matriarch
        • Plasma Cannon turn rate while firing increased by 29%.
        • Plasma Cannon damage reduced by 30%.
    • Rioter
      • Head armor obliteration value increased from 80 to 125.

Designer Note :
There were feedback concerns that the Plasma Cannon special move dealt an excessive amount of damage, especially on the Normal and Hard difficulties where it had the potential to kill a player with full armor and health on a multiplayer server. As such, we tweaked its damage down. To compensate for the reduction of damage, we boosted the turn rate while she is firing the Plasma Cannon to allow her to better track players with it.

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.

  • Weapons
    • HRG Incision
      • Removed Zed weak spot lock-on.
      • Increased base damage of primary fire from 350 to 400.
      • Ammo price per magazine increased from 11 to 14.
      • Starting spare magazines upon Trader purchase reduced from 14 to 12.
    • HRG Winterbites
      • Removed freeze affliction from the impact. This will reduce the freeze application rate by ~29% for shots that directly hit Zeds. The explosions will continue to have the same freeze application rate.
      • Base damage of impact increased from 30 to 40.
      • Ammo price per magazine increased from 10 to 12 for Single.
      • Ammo price per magazine increased from 20 to 24 for Dual.
    • Mosin Nagant
      • Fire rate increased by 15%.
      • Block damage mitigation reduced from 50% to 40%.
      • Parry damage mitigation reduced from 60% to 50%.
    • Riot Shield & Glock 18
      • Block damage mitigation increased from 50% to 60%.
      • Bash impact damage increased from 25 to 35.

Designer Note :
We removed the HRG Incision’s weak spot lock-on capabilities. There were multiple recommendations from the community survey to remove it as it made the weapon gameplay feel too simplistic and unrewarding. There was also a lot of concerns that the damage output for the weapon felt a little underwhelming, so to compensate for the removal of the lock-on functionality and address the damage concern, we boosted the damage of the primary fire. We are also taking note of the EMP affliction feedback and will keep an eye on this for future adjustments if needed.

The HRG Winterbites provide a strong, early, and cheap method to freeze Zeds. As such, there was a lot of concern that the freeze affliction was too good, especially against the larger Zeds, such as the Scrakes and Fleshpounds. We removed the freeze affliction on the impacts to help alleviate this concern. It should feel harder to freeze large Zeds while closely maintaining its previous freeze rate for smaller Zeds. We also increased the damage of the projectile impacts to address feedback that the damage output felt too low.

The Mosin Nagant’s fire rate has been increased to address multiple feedback concerns about it feeling too slow on fire to be as effective as the other Sharpshooter weapons. Also, Its damage reduction on block and parry has been adjusted down as the previous values felt a tad too high and allowed for effective reduction of damage.

The Riot Shield aspect of the Riot Shield & Glock 18 felt underwhelming, and we decided to increase its damage mitigation to allow players to absorb more damage. We also boosted the damage of the bash impact. This damage increase should deal enough damage to kill crawlers if they are the primary target struck by the shield.

As always, we’d like to hear the community's feedback on these changes. You can do so by visiting and posting on the official Tripwire Interactive Killing Floor forums at : https://forums.tripwireinteractive.com/forum/killing-floor-2

So items from featured tab are unavailable for purchase right now.
The changelog looks small, doesnt even look like some bug reports were looked at and worked on (if i launch obj steam fortress and hear buyo's voice as a trader instead of lockhart after 3 months of it being that way, i will definetly know that you rarely look at the bug reports)
Edit: yep, as i expected, obj steam fortress has incorrect trader pod voice lines
Edit2: and store is now online

Skip Trader keyboard button doesn't work. Can anyone confirm?
I had this issue a few weeks ago where no matter what key I set to skip trader, it would not work. Deleting my INI files (...\Documents\My Games\KillingFloor2\KFGame\Config) fixed this issue for me. :)

Purchases worked fine for me. The main issue seems to be a freezing lag upon completion of a match when it ends and starts to display XP, and more, including if getting a Seasonal ticket.

Nice to know that the Matriarch kills objective is impossible for people who haven't played the beta. I still think that the number of kills required to complete the objective should be reduced to 4.

If we obtain Riot Shield.

Can we put Riot Shield on our back when not using it??

it's very weird and not logical for now, make me think : Where does the shield go?

The bug when joining a 2nd game is still here in the full release. Wrote about it in beta 1 i think it was.
If you have finished 1 game or died or whatever... And log out from this server. Then try to log into another game / server... the game will crash into windows while loading into 2nd game.
Workaround: Play 1 game at a time (1 server at a time) if you want to play another game, or log onto another server, you will have to quit game into windows and start game again.,..

Seems after "Yuletide Beta 1" you can only do 1 game/serverlogon at a time without crashing the game.

I don't have access to the new zombie skins or the seasonal content, I've validated my files and restarted my PC etc but it's not showing. Any ideas?


Feb 28, 2018
Can we up the "spawn" rate of the matriarch for this event. played about 7 matches and havne't faced her yet. Defeating her 10 times seems a bit too much at this point, especially since I don't have all the time and it will feel like a grind just to face her.

I can confirm. Had two beta periods worth of a head start and i've only faced her 8 times. I don't see how non-participants can even do this objective.

According to this thread everyone will get the seasonal objective at the end of the event due to an unintended problem with the game's kiling blow on the Matriarch not correctly reading and applying to everyone.

In the beta I did get her via endless mode but I only played 2 bosses and restarted (wave 1-10) lots of times.

THIS!! I have played a good 30+ GAMES now, and she has only appeared ONCE so far.
The spawn rates are INSANELY LOW.

Am I the only one who feels the update to the redscreen effect when you're below half health is a tad extreme?
Combine it with Bloat bile, Trapper Beam or whatever and it is a nightmare to see anything - curious why this was changed, were people really that in need of a notification they were dying?
