Killing Floor Russian Localization Fonts

This page covers LazyKFWiki’s notes on Russian interface fonts. The fix targets .int files that control font groups used by menu chat, chat history, console text, in-game chat input, and pop-up messages.

Backup Files

LazyKFWiki linked clean .int files for rollback:

Back up your current files before editing:

KillingFloor\System\GUI2K4.int
KillingFloor\System\XInterface.int
KillingFloor\System\KFMod.int

What Each File Controls

UI area	File	Group or array
Lobby chat input and menu chat fields	`GUI2K4.int`	`fntUT2k4Menu`
Chat history in map voting, kick voting, and similar menus	`GUI2K4.int`	`fntUT2k4ServerList`
Console	`XInterface.int`	`HudBase`, `FontArrayNames`
In-game chat input and pop-up messages	`KFMod.int`	`HUDKillingFloor`, `FontArrayNames`

The exact array index can depend on GUI size, resolution, and related settings. LazyKFWiki notes that replacing the whole array is often more reliable than changing only one suspected element.

Font Replacement Idea

The original note points to replacing old or incompatible font references with Russian-capable fonts:

ROFonts.ROBtsrmVr -> ROFonts_RUS.ROArial
ROFontsTwo.ROArial24DS -> ROFonts_Rus.ROArial24

The goal is to stop Cyrillic text from rendering with the wrong font or disappearing in UI areas that still use inherited Unreal Tournament 2004 font groups.

Practical Editing Steps

Close Killing Floor.
Back up GUI2K4.int, XInterface.int, and KFMod.int.
Open one file at a time in a text editor that preserves encoding.
Search for the groups listed above.
Replace incompatible font references with Russian-capable alternatives.
Save, start the game, and test the affected UI.

What To Test

Lobby chat input.
Map-vote and kick-vote chat lines.
Console readability.
In-game chat input.
Pop-up messages.
Different GUI sizes and resolutions.
