Killing Floor 2 Summer Opt-In Beta 1 (PC Build 1114) Is Now Available!

Shodan/ Giugno 2, 2021/ Killing Floor 2

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 own dedicated server within the install for your own personal hosting needs for this version.

Interstellar Insanity

  • You made it! The moon landing was performed without any complications! Well, almost… Anyway, this research station has gone quiet for a while so you must check if everything is going well. But considering that communications were cut off a few days ago, the situation does not look good, so don’t let your guard down. On top of that, there are also 2 alternative scenarios that you may experience that will imply an additional challenge level: Arachnophobia and Scavenger weekly modes. But there is some good news! At least you will be able to use the new fancy tools from Horzine Research Group, the HRG Bastion and HRG Blast Brawlers, that were being developed in this station. Final advice: it may take you some time to get used to the moon’s gravity.

Special Note for Steam & EGS Armory Season Pass Holders:
During the start of Beta 1 for Summer 2021, the Inventory Weapon Skins tied to the new FAMAS Masterkey and Thermite Bore will be granted to all Armory Season Pass holders on Steam and EGS. This will unlock full access to these weapons and their associated variant skins for those Armory Season Pass holders that choose to opt-into the Beta update. As this new content is not present in the current non-beta live build, Armory Season Pass holders on Steam and EGS who don’t opt-in to the Beta will still receive these inventory skins but will appear with missing thumbnails, names, and descriptions that do not unlock anything in game or affect game behavior. Don’t be alarmed as these will appear as expected if you choose to opt-in Beta later, or wait until the Summer Update is released in the live branch for final release.

Designer Notes :
We have integrated the skip trader vote system in the Versus game mode, that will make the process of skipping the trader easier and clearer for players. Only the Survivor players will vote.

We were aware of the stun reliability problems of the Crossbow and Compound Bow headshots against Scrakes, and the frustration that it may cause. We have worked on improving the system and now the headshots stun power should be applied correctly to the Scrakes, and stun them with more consistency.

The Compound bow was not in a bad spot but we think that one of their fire modes, the cryo arrow, was not performing as good as the other one, the sharp arrow. So we boosted the explosion of the cryo arrow to allow a higher damage capacity and more effective freeze effect against groups of Zeds. Finally, we increased the ammo capacity of the weapon to encourage the use of more cryo arrows to players that are usually conservative with ammo, regarding that this fire mode does not leave pickup as the sharp arrows.

We made some adjustments on the Hemogoblin to improve its viability as a medic weapon. Apart from the bleeding mechanic, the semi-automatic fire mode was a bit unbalanced, so we increased the damage of the primary fire, and speeded up the reload time. We also increased the healing of each dart to make it slightly more impactful, in a midpoint between the HMTech-401 and the HRG Incision.

We implemented several nerfs to the Berserker and Field Medic perks, mostly related to their surviving capacities, as we had a lot of community reports about both perks overperforming in that aspect, even more if their capacities were combined. We love to see the different synergies between perks and strategies that our community creates, but we would like to have every perk in a similar balance point, and each of the 10 perks to be equally relevant in the game.

Finally, we made some adjustments on Demolitionist’s Extra Rounds and Support’s High Capacity Magazines, to improve their viability, as they were underperforming compared to their counterpart skill and were less prefered by most players.

Bug Fixes
Also mentioned in the 2020 Killing Floor 2 ‘State of the Game’ our goal is to bring to the community a continued stream of community-reported bug fixes for each update throughout the year.

  • Fixed an issue where the weekly challenge UI would be out of sync from the current weekly cycle.


  • Fixed an issue where the Trader Path would not path across the main street on Dystopia.


  • Altered the text string for the HRG Incendiary Rifle in the trader pod in Russian to allow it to fit within the UI.
