Castle Crashers is a 2D indie hack-and-slash video game developed by The Behemoth. The game was released in 2008 for Xbox 360. However, the game made it to other platforms later on. Here’s how to play Castle Crashers on Linux.
Castle Crashers is not a Linux game, but thanks to Proton, it works fine on Linux. However, the Proton tool only works in Linux through the Steam client. So, you must install the Steam Linux client on your Linux PC before continuing.
Install Steam
To get Steam for Linux working on your computer, open up a terminal window on the Linux desktop. To do that, click Ctrl + Alt + T on the keyboard. Alternatively, search for “Terminal” in the app menu and launch it that way.
When the terminal window is open and ready to use, follow the Linux installation instructions below that correspond with the Linux OS you currently use.
Ubuntu
To get Steam working on Ubuntu, you can install it with the apt installation command down below.
sudo apt install steam
Debian
To get Steam working on Debian, you’ll have to download the DEB package onto your computer. You can download the Steam DEB package onto your computer using the wget download command below.
wget https://steamcdn-a.akamaihd.net/client/installer/steam.deb
After downloading the latest release of Steam to your Debian PC, the installation can begin. Using the dpkg command below, install Steam on your computer.
sudo dpkg -i steam.deb
Once the Steam DEB package is configured on your Debian PC, you’ll need to run the apt-get install -f command. This command will allow you to correct any dependency issues that appeared during the installation.
sudo apt-get install -f
Arch Linux
Steam is available to Arch Linux users via the “multilib” software repository. However, you’ll need to enable this software repository because it isn’t always enabled. To do this, open up the /etc/pacman.conf file in your favorite text editor (as root).
After opening up the text file in an editor as root, locate the “multilib” section of the file. Then, remove the # symbol from in front of it and the lines directly below. When done, save your edits and exit the editor.
Now that everything is configured, re-sync your Arch Linux system with the command below.
sudo pacman -Syy
Finally, install the latest release of Steam onto your Arch Linux computer.
sudo pacman -S steam
Fedora/OpenSUSE
To get Steam working on Fedora or OpenSUSE, it is best to go with the Flatpak installation instructions in this guide. However, if you do not want to install Steam through Flatpak, it is possible to install Steam through software repositories included in the operating system.
Flatpak
If you’d like to use the Flatpak release of Steam on your computer, you’ll need to first set up the Flatpak runtime on your computer. To set up the Flatpak runtime, follow along with our setup guide on the subject.
After setting up the Flatpak runtime on your computer, the installation of Steam can begin. Using the two commands down below, install the latest release of Steam.
flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
