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!

Currently implemented:

Authenticate with Epic (can import authentication from EGS installation [Windows only])
Download and install games
Update installed games (not well tested/potentially buggy)
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. In the first step you will log in and in the second one you are required to copy an exchange code from a JSON site into the command line. On Windows you can add --import to attempt to import the session from the Epic Games Launcher, if it is installed and you're logged 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 --install Anemone

Important: the name used for these commands is the app name, not the game's name! The app name is included in the games list after the title.

List installed games and check for updates

$ legendary --list-installed --check-updates

Launch (run) a game with online authentication

$ legendary --launch Anemone
