Legendary Game Launcher

A free and open-source Epic Games Launcher replacement

Legendary (named after the next highest tier in item rarity) is an open-source game launcher that can download and install games from the Epic Games Store on Linux and Windows.

Right now it is in an early public pre-release stage and still needs a lot of work to work. But it does work!

What works:

• Authenticate with Epic
• Download and install games
• Update installed games and their DLC
• Launch games with online authentication

Planned:

• Better Linux and WINE support
• Importing installed games from the EGS launcher
• PyPI distribution
• Miscellaneous optimizations
• Simple GUI for managing/launching games
• Lots and lots of bug fixes and refactoring...

Requirements

• python 3.8+
• requests

How to install

• Windows (standalone): Download the latest EXE from GitHub
• Linux/Windows (requires setuptools to be installed): python3.8 setup.py install

A PyPI package will follow once it has gotten more testing.

The Windows .exe was created with PyInstaller and will run standalone without python being installed.

Quickstart

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.

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 download 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.
