How to play Dungeon Defenders on Linux

Dungeon Defenders is a hybrid multiplayer video game developed by Trendy Entertainment. The game was released on Microsoft Windows, Xbox, iOS, Mac OS, Linux, etc. Here’s how to play the game on Linux.

Getting Dungeon Defenders working on Linux

Dungeon Defenders is a native Linux game, but the native release of the game runs poorly. So instead, those looking to play Dungeon Defenders must use Proton.

To make use of Proton for Dungeon Defenders, you need to install the Linux release of Steam. You can get the Steam app working on Linux via the official Linux release.

Install Steam

Installing Steam on Linux requires the terminal. To open up a terminal, press Ctrl + Alt + T on the keyboard. Or, search for “Terminal” in the app menu and launch it that way.


Installing Steam on Ubuntu is very easy, as it is included in the official software sources. To get it working, enter the apt install command below.

sudo apt install steam


If you’d like to use Steam on Debian, you’ll have to download the official DEB package from Valve. To download the package, use the following wget download command below.

wget https://steamcdn-a.akamaihd.net/client/installer/steam.deb

When the package file is downloaded to your computer, the installation can begin. Using the dpkg command down below, install the latest release of Steam.

sudo dpkg -i steam.deb

After setting up the Steam DEB package on your computer, you’ll need to correct any dependency errors that may have occurred during the installation.

sudo apt-get install -f

Arch Linux

Steam is available on Arch Linux via the “multilib” software repository. To get it working on your computer, you’ll first need to enable the repo.

To enable the “multilib” software repository on your computer, open up the /etc/pacman.conf file with your favorite text editor (as root). Once open, find “multilib” and remove the # symbol from in front of it, as well as lines down below.

After editing, save the edits and close the editor. Then, use the pacman -Syy command to re-sync Arch with the official software repos.

sudo pacman -Syy

Finally, install the Steam app.

sudo pacman -S steam


Steam works on both Fedora and OpenSUSE using software repositories included in the operating system. However, Steam works better with Flatpak on these OSes, so we suggest using the Flatpak release instead.


To get Flatpak working on Linux, you’ll install the Flatpak runtime and configure the Flathub app store. Getting the Flatpak runtime is relatively easy. To do it, please follow our guide on the subject.

After setting up the runtime, you’ll be able to get the Flathub app store working. Using the flatpak remote-add command below, configure Flathub.

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

Finally, set up the Steam application using the flatpak install command below.

flatpak install flathub com.valvesoftware.Steam

Step 1: Find the “Steam” button in Steam and click on it with the mouse. Then, select the “Settings” button inside the menu to open up the Steam settings area.

Inside of the Steam menu, find the “Steam” play section and select it. Then, select both the “Enable Steam Play for supported titles” box and “Enable Steam Play for all other titles.”

Step 2: After selecting the checkboxes, find the “Store” button inside Steam and load up the Steam store. Once inside the Steam store, locate the search box.

In the right-click menu, select “Properties” with the mouse to open up game properties. Then, click on. “Force the use of a specific Steam Play compatibility tool.”

Select the latest release of Proton. Dungeon Defenders doesn’t run well natively on Linux, so this step is crucial.

Step 5: Find the blue “INSTALL” button on the Dungeon Defenders game page and click on it to install the game to your Linux PC. The installation will take some time.

When the installation of Dungeon Defenders is complete, the blue “INSTALL” button will become a green “PLAY” button. Select this button to start up the game.
