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 folder for your own personal hosting needs for this version.

Tidal Terror

  • Off the coast of Scotland in the East Shetland Basin of the North Sea, we’ve located a secret research lab hidden away in an oil drilling rig. We can only imagine what horrors the Patriarch and his cohorts have been up to here in this remote location. By the way, if you are one of those people who like to try different weapons, we have a new weekly mode for you, Arsenal Ascent, in which you will be swapping weapons as you kill Zeds. And if that weren't enough, the Horzine Research Group just released two new products, the HRG Head Hunter and the HRG Crossboom, for Sharpshooter and Demolitionist mercs respectively. Hurry up and take a look!

Addressed Community Feedback
As mentioned in the 2021 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:


  • Survivalist Perk
    • Option to choose base grenade and initial weapon
    • The initial weapon will be granted only at the beginning of the match.
    • The base grenade will be granted at the beginning of the match, but can also be changed during trader time.
    • Perk level 15 adds Medic Grenade or Molotov Cocktail to the rotation, depending on the perk skill choice.

  • New order rules in the Weapon Skin section in the inventory.
    • First ordered by trader price, then rarity (common to precious), then quality (battle-scarred to mint).


  • Weapons
    • FAMAS Masterkey
      • Alt-fire spread decreased by 20%
      • Alt-fire fire rate increased from 50 RPM to 78 RPM
      • Alt-fire animation speed increased by 70%

    • Minigun
      • Movement speed when winding up increased 12.5%
      • Movement speed when firing increased 500%
      • Rotation speed when firing increased 105%
      • Reload speed increased 20%
      • Equip speed increased 30%
      • Put Away speed increased 30%

  • Perks
    • Firebug
      • Inferno (level 25 skill)
        • Rework of the skill.
        • New functionality is: During Zed time, your fire damage over time spreads to all surrounding Zeds.

Designer Notes :
Survivalists had to rely on randomness every time they started a match, but that is over. Now, Survivalists can choose their initial weapon and grenade on the Perk screen. We have left the “random option” available for those who prefer it. In addition to that, for Level 15+ Survivalists, the Medic Grenade or the Molotov Cocktail will be added to the rotation, depending on whether the player has chosen the “Ammo Vest” or “Weapon Harness” skill. But players can keep choosing another grenade if they want. Finally, as the grenade is linked to the perk skill, and this can be changed during trader time, players will also be able to change their grenade during this time, keeping the number of grenades they already had.

The order in the Weapon Skin section in the inventory was a bit chaotic, with different skins of different weapons mixed. We have added some rules to improve it, and now you will see all the skins of the same weapon grouped together. The skins will be ordered by weapon trader price, then rarity (common to precious), and then quality (battle-scarred to mint).

Regarding balance, we have made adjustments in two weapons, keeping in mind the community feedback. For the FAMAS Masterkey, we have increased the fire rate for the alt-fire (shotgun fire), which was very slow to use, and it was hard to swap between alt-fire and main fire. Now you can shoot faster, and combine main fire and alt-fire better, making this weapon more versatile and dynamic in play style. We also have slightly adjusted the spread, which will help to improve the effectiveness of the weapon.

The other balanced weapon is the Minigun. The main disadvantages of this weapon were its mobility restrictions, so that’s what we’ve been focusing on. Now, you will have the same firepower as before, but you will be able to move and reload faster.

Finally, we have made a complete rework of the Inferno perk skill for the Firebug. We expect that now this skill performs better than the previous one, creating a good alternative to the other Firebug level 25 skill, Pyromaniac.
