Legendary
A free and open-source Epic Games Launcher alternative
Legendary is an open-source game launcher that can download and install games from the Epic Games platform on Linux and Windows. Its name as a tongue-in-cheek play on tiers of item rarity in many MMORPGs.
Right now Legendary is in beta and not feature-complete. You might run into some bugs or issues. If you do please create an issue on GitHub so we can fix it.
Please read the the config file and cli usage sections before creating an issue to avoid invalid reports.
Note: Legendary is currently a CLI (command-line interface) application without a graphical user interface, it has to be run from a terminal (e.g. PowerShell)
What works:
- Authenticating with Epic's service
- Downloading and installing your games and their DLC
- Delta patching/updating of installed games
- Launching games with online authentication (for multiplayer/DRM)
- Syncing cloud saves (compatible with EGL)
- Running games with WINE on Linux
- Importing/Exporting installed games from/to the Epic Games Launcher
Planned:
- Simple GUI for managing/launching games
- Better interfaces for other developers to use Legendary in their projects
- Lots and lots of bug fixes, optimizations, and refactoring...
Requirements
- Linux or Windows (64-bit)
- python 3.8+ (64-bit on Windows)
- PyPI packages:
requests, optionallysetuptoolsandwheelfor setup/building
How to run/install
Package Manager
Several distros already have packages available, check out the Available Linux Packages wiki page for details.
Currently this includes Arch, Fedora, openSUSE, and Gentoo but more will be available in the future.
Note that since packages are maintained by third parties it may take a bit for them to be updated to the latest version. If you always want to have the latest features and fixes available then using the PyPI distribution is recommended.
Standalone
Download the legendary or legendary.exe binary from the latest release
and move it to somewhere in your $PATH/%PATH%. Don't forget to chmod +x it on Linux.
The Windows .exe and Linux executable were created with PyInstaller and will run standalone even without python being installed. Note that on Linux glibc >= 2.25 is required, so older distributions such as Ubuntu 16.04 or Debian stretch will not work.
Python package
Prerequisites
To prevent problems with permissions during installation, please upgrade your pip by running python -m pip install -U pip --user.
Tip: You may need to replace
pythonin the above command withpython3.8on Linux, orpy -3.8on Windows.
Installation from PyPI (recommended)
Legendary is available on PyPI, to install simply run:
pip install legendary-gl
Manually from the repo
- Install python3.8, setuptools, wheel, and requests
- Clone the git repository and cd into it
- Run
pip install .
Ubuntu 20.04 example
Ubuntu 20.04's standard repositories include everything needed to install legendary:
sudo apt install python3 python3-requests python3-setuptools-git
git clone https://github.com/derrod/legendary.git
cd legendary
pip install .
If the legendary executable is not available after installation, you may need to configure your PATH correctly. You can do this by running the command:
echo 'export PATH=$PATH:~/.local/bin' >> ~/.profile && source ~/.profile
Directly from the repo (for dev/testing)
- Install python3.8 and requests (optionally in a venv)
- cd into the repository
- Run
pip install -e .
This installs legendary in "editable" mode - any changes to the source code will take effect next time the legendary executable runs.
Quickstart
Tip: When using PowerShell with the standalone executable, you may need to replace legendary with .\legendary in the commands below.
To log in:
legendary auth
Authentication is a little finicky since we have to go through the Epic website. The login page should open in your browser and after logging in you should be presented with a JSON response that contains a code, just copy and paste the code into your terminal to log in.
On Windows you can use the --import flag to import the authentication from the Epic Games Launcher. Note that this will log you out of the Epic Launcher.
Listing your games
legendary list-games
This will fetch a list of games available on your account, the first time may take a while depending on how many games you have.
Installing a game
legendary install Anemone
Important: the name used for these commands is the app name, not the game's name! The app name is in the parentheses after the game title in the games list.
List installed games and check for updates
legendary list-installed --check-updates
Launch (run) a game with online authentication
legendary launch Anemone
Tip: most games will run fine offline (--offline), and thus won't require launching through legendary for online authentication. You can run legendary launch <App Name> --offline --dry-run to get a command line that will launch the game with all parameters that would be used by the Epic Launcher. These can then be entered into any other game launcher (e.g. Lutris/Steam) if the game requires them.
Importing a previously installed game
legendary import-game Anemone /mnt/games/Epic/WorldOfGoo
Note: Importing will require a full verification so Legendary can correctly update the game later.
Sync savegames with the Epic Cloud
legendary sync-saves
Note: When this command is run the first time after a supported game has been installed it will ask you to confirm or provide the path to where the savegame is located.
Automatically sync all games with the Epic Games Launcher
legendary -y egl-sync

Environment variables
Legendary supports overriding certain things via environment variables, it also passes through any environment variables set before it is called.
Legendary specific environment variables:
LGDRY_WINE_BINARY- specifies wine binaryLGDRY_WINE_PREFIX- specified wine prefixLGDRY_NO_WINE- disables wineLGDRY_WRAPPER- specifies wrapper binary/command line
Note that the priority for settings that occur multiple times is: command line > environment variables > config variables.

Legendary supports some options as well as game specific configuration in ~/.config/legendary/config.ini:
