F.A.Q.

This page contains answers to frequently asked questions about the game and our servers. Before reporting your issue, make sure it’s not in the list below.

Login Issues

Failed launching URL Package version mismatch Error

This can be an error for any package, for example:

Failed launching URL Package 'Flares' version mismatch
Failed launching URL Package 'BlackCat' version mismatch

If you encounter this problem when joining our servers, do the following:

1. Completely close Killing Floor.
2. Open your game folder and find the Cache folder.
3. Rename or move the folder - this will clear the cache and allow you to download all server resources again.
4. Try joining the server again.

Why can’t I join with a pirated version (Non Steam)?

First, let’s answer the question “why pirated versions are not supported”:

• It’s illegal.
• It compromises game integrity (cheats and game data forgery).
• The number of players in our community using pirated versions remains very low, and we must prioritize the majority.

Now, will pirated versions be supported in the future?

Possibly, but only if at least a third of the community is interested in it.

I can’t click the Ready button when joining the server, what should I do?

The ready button may be inactive in two cases:

1. If your character is still in the game (cases of critical client errors and closing the game via task manager).

To solve the problem, you need to wait approximately 30-60 seconds for your character to be completely removed from the game, and then try joining the server again.

2. If for some reason the database doesn’t respond to data loading requests.

To solve the problem, try joining other project servers and determine if this is a temporary issue or a persistent one. If there are no people on other project servers and you can’t join them either, the problem is likely global and requires contacting the administration through Discord.

TIP: try reconnecting to the server several times: use the reconnect command in the server console.

I used to play on project servers, but now I have no progression. How do I restore my perks?

Unfortunately, perk recovery was available for a limited time and is no longer available.

If you wish, you can support the project and get accelerated perk progression with Premium, which will help you easily and quickly level up your perks.

I got banned from the server, what should I do?

Depending on the type of ban (kick from one map, temporary ban, permanent ban), you can try joining the servers again after some time.

If you believe you were banned by mistake, write about it on the Support forums through Discord of the project.

Game Interface Issues

I see ~~~~~ instead of text in the game, how do I fix it?

Ready-made patch (for English game client):

• Download

Fix manually:

• Set the game language to anything other than Russian in the Steam library (for example: right-click the game -> Properties -> Language -> English).
• Open the System folder of your game client your steam path\steamapps\common\killingfloor\System.
• List of files to edit:
  • Engine.int
  • GUI2K4.int
  • KFMod.int
  • ROEngine.int
  • UnrealGame.int
  • XInterface.int
• Open each file in sequence and make replacements according to the table:

How do I enable third-person view?

Use the F4 key or type the console command behindview 1

Server Features Questions

What are Bonus Points (BP) and where can I get them?

• Bonus Points are a currency on our servers used to purchase items and perform various actions in the game.
• Bonus Points can be earned by completing daily tasks.

How is victory/defeat counted on servers with classic mode?

• Defeat is counted if the first wave was passed and all players died after the “second chance” or on the boss wave.
• Victory is counted after successfully defeating the boss.

Why can’t I change maps on the server?

Depending on the server type, at the end of each game every player can choose from 3-5 random maps.

Maps can be manually changed by server moderators and administrators.

I want to upload my map to the server. How do I do that?

Create a new topic in the Support forums through Discord of the project. We will review your request and respond in the thread.

Is it possible to buy admin rights or moderator rights?

No. Moderator recruitment is free and only available to veteran community members.

Game Client Optimization

How do I increase the client cache file retention time?

• The standard cache retention period is 30 days
• Open KillingFloor.ini and find the parameter PurgeCacheDays=30
• Replace 30 with 300 or another value
• This change will help you avoid re-downloading server files

Speed up game startup

Note: These steps are not required for powerful computers.

1. To speed up Killing Floor startup, download the file NoIntro.rar , extract it and place the NoIntro.rom file in the Maps folder. In KillingFloor.ini, replace the line LocalMap=KFIntro.rom with LocalMap=NoIntro.rom.

2. For fast map switching, modify the parameters in the killingfloor.ini file (recommended for weak computers). Go to KillingFloor.ini, find the [Engine.GameEngine] section and replace the CacheSizeMegs parameter according to your RAM amount:

256 Mb RAM or less CacheSizeMegs=32
512 Mb RAM CacheSizeMegs=64
768 Mb RAM CacheSizeMegs=128
1 Gig RAM or more CacheSizeMegs=256

3. Disable PreCaching:

[ALAudio.ALAudioSubsystem]
Change UsePrecache=True to UsePrecache=False

[Engine.LevelInfo]
Change bNeverPrecache=False to bNeverPrecache=True

[Engine.NullRenderDevice]
Change UsePrecaching=True to UsePrecaching=False

[D3DDrv.D3DRenderDevice]
Change UsePrecaching=True to UsePrecaching=False

[D3D9Drv.D3D9RenderDevice]
Change UsePrecaching=True to UsePrecaching=False

[OpenGLDrv.OpenGLRenderDevice]
Change UsePrecaching=True to UsePrecaching=False

[PixoDrv.PixoRenderDevice]
Change UsePrecaching=True to UsePrecaching=False
