KF2 Autumn 2023 Beta 1 Changelog

To opt into this beta on Steam, join the "preview" branch available in the Beta drop-down list. Admins will need to use the following SteamCMD flag:

  • app_update 232130 -beta preview

To opt into this beta on EGS, the Beta will be accessible within KF2 owners’ game libraries as a separate install called “Killing Floor 2 Beta”. Users may need to restart their EGS launcher for the Beta to populate and be accessible to install. Progress for stats and inventory is shared between both versions on EGS so for users switching between Beta and Live be sure to sync your game data to use the latest timestamp to prevent any lost progress from participating in the Beta. The Beta on EGS also includes its dedicated server within the install folder for your hosting needs for this version.

Last Hans Standing

  • Scanners all over the world found Hans Volter’s hidden castle. Veiled by the Alpine fog and forests, Castle Volter seems to be a fortress in disguise. Your team has enough intel to determine that the castle is Volter’s personal clone laboratory. The time for the final assault to put the old man down for good has come in the new official map: Castle Volter.

Nevertheless, every operation needs funding. Horzine has put a nice and shiny price tag on some unusually dangerous Zed specimens. Hunt them down on the new Bounty Hunt Weekly Mode and make some good Dosh. However, we must warn you that the longer it takes you to take down the Bounties, the more dangerous they’ll be.
Try out the brand new HRG 93R, a burst-fire backup pistol. Tired of your old 9mm? This new handgun weighs like a butterfly but stings like a bee. Make sure you check it out on your Perk menu.
We hope you enjoy the new content coming up this Halloween!

Addressed Community Feedback
As mentioned in the 2022 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


  • Weekly mode Selector:
    • Added a way to pick any desired Weekly Outbreak as game mode
    • Here are more details on how the Weekly Selector can be used:
      • Find a match
        • This option prioritizes finding a populated Weekly Outbreak server regardless of the type first. If it needs to perform a server takeover to give the player a Weekly Outbreak server within their region, it will then be set to the current active weekly index rather than any hidden preference set within Create a Match or Solo.

      • Create a match
        • Creates a match with the chosen Weekly Outbreak, taking over an existing empty server enabled for takeover based on the requested Weekly Outbreak chosen.

      • Solo Offline
        • Lets you play locally on Solo mode for any Weekly Outbreak. Pick your favorite one using the selector (same filters as Create a Match).

  • Server Browser
    • Allows the player to search for a specific Weekly Outbreak, showing an icon in the main list and indicating the weekly that the server hosts within the details.

    • How to configure your server
      • Add the following line to your batch file: "?WeeklySelectorIndex="
        • The will correspond to the desired Weekly. The list is the following:
          • 1: Boom
          • 2: Cranium Cracker
          • 3: Tiny Terror
          • 4: Bobble Zed
          • 5: Poundemonium
          • 6: Up, Up, and Decay
          • 7: Zed Time
          • 8: Beef Cake
          • 9: Blood Thirst
          • 10: Coliseum
          • 11: Arachnophobia
          • 12: Scavenger
          • 13: Wild West London
          • 14: Abandon All Hope
          • 15: Boss Rush
          • 16: Shrunken Heads
          • 17: Arsenal Ascent
          • 18: Primary Target
          • 19: Perk Roulette
          • 20: Contamination Zone
          • 21: Bounty Hunt

The current Weekly Outbreak rotation will continue working as usual, updated weekly. Weekly rewards will only be granted if the Current Weekly is chosen. Playing any custom Weekly Outbreak won’t grant any reward.

Designer Notes:
We agreed that the heavily requested ability for players to set their Weekly Outbreaks is a must. The Weekly Selector is now in the game! Choose your favorite Weekly Outbreak to play, or find any specific match in the server browser from our expansive list of Weekly Outbreaks.

Regarding balance, we have made tweaks in some weapons following the feedback from the Community:

The Killerwatt was powerful but could be more comfortable to use. We sped up its alt-fire charge rate, increased the default fire mode damage, and made it easier to control while alt-firing.

The Head Hunter and the Reducto Ray had a shared problem: it took too long for Zeds with altered sizes (either heads or full bodies) to return to their original state. Now, recovery rates are sped up.

The crosshair was enabled for the HRG Vampire, which players will find handy!

We heard your feedback regarding the ammo price for one of the most ammo-consuming perks of the game, the SWAT. We hope players enjoy the ammo pricing adjustment.

Many players also expressed that these 3 Support skills weren’t being used as they did not feel enticing enough alternatives to their counterparts. We believe these additions will make choices more interesting for players. The addition of real-time reloads for mag-feed and non-mag-feed guns will allow players to fire off more shots in real-time when supports find themselves in need of more ammo.

Player input suggested that Acidic Rounds was a skill that caused more harm than helped the cooperative playstyle. We’ve taken that feedback and revamped the skill, maintaining the poison theme: now the darts shot from Medic weapons cause more damage and break the Zeds’ poison resistance quicker, allowing the Medic to help in specific situations instead of poisoning Zeds in unwanted scenarios.
