How to play Killing Floor 2 on Linux

Killing Floor 2 is an FPS shooter published by Tripwire Interactive. The game is playable in both single-player as well as multiplayer and focuses on the events of Killing Floor 1, where a bio-tech firm created zombies that terrorize the world. In this guide, we will show you how to get the game working on Linux.

Getting Killing Floor 2 working on Linux

Getting Killing Floor 2 working on Linux has got to be done with the Steam Linux client. The reason is that it relies heavily on Proton and the Steam Play feature to run the game. So, you must install the Linux Steam client.

Install Steam

To install Steam, launch a terminal window and follow the directions below that corresponds with the Linux OS you currently use.

Ubuntu

If you’re using Ubuntu Linux, it is possible to install Steam on your computer using the apt install command below.

sudo apt install steam

Debian

Debian users can run Steam no problem. However, the only way to install it through the official Debian repositories is to enable the “non-free” software source, which can be confusing to new users. A much better way to go is to download the official DEB package directly from the internet.

Using the wget command in a terminal window, download the latest Steam DEB package to your computer.
wget https://steamcdn-a.akamaihd.net/client/installer/steam.deb

After the Steam package is done downloading, you can load up the app on your computer using the following dpkg command.

sudo dpkg -i steam.deb

Be sure to run sudo apt-get install -f after setting up the Steam package to correct any dependency issues that may arise during the installation.

Arch Linux

On Arch Linux, the Steam app is not difficult at all to get working. To install it on your system, all you need to do is run the following Pacman command in a terminal window.

sudo pacman -S steam

Fedora/OpenSUSE

Both Fedora and OpenSUSE can run Steam, but you may need to enable third-party software sources to do so, like RPM Fusion. Instead, consider following the Flatpak installation instructions. Flatpak is pre-configured on Fedora, and it simple to get working on OpenSUSE.

Flatpak

The Steam app is available to all Linux users via the Flathub Flatpak app store. If you’re looking to get the Flatpak version of Steam working for your system, the first thing you must do is install the Flatpak runtime. To do that, follow our in-depth guide on the subject.

After setting up the Flatpak runtime on your computer, use the flatpak remote-add command to set up the Flathub app repository. This repository is necessary to install the latest Steam Flatpak app.

flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

Now that the Flathub repo is set up on your computer, the installation of Steam can begin. Using the flatpak install command, download and install the latest Flatpak version of Steam on your computer.

flatpak install flathub com.valvesoftware.Steam
