# Legendary
|
|
## A free and open-source Epic Games Launcher replacement
|
|
|
|
|
|
[](https://discord.gg/UJKBwPw) [](https://twitter.com/legendary_gl)
|
|
|
|
Legendary is an open-source game launcher that can download and install games from the Epic Games Store on Linux and Windows.
|
|
It's name as a tongue-in-cheek play on tiers of [item rarity in many MMORPGs](https://wow.gamepedia.com/Quality).
|
|
|
|
Right now it is in an early public testing stage and still needs a lot of work to work. But it does work!
|
|
|
|
**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)
|
|
- Running games with WINE on Linux
|
|
|
|
**Planned:**
|
|
- Simple GUI for managing/launching games
|
|
- Importing installed games from the EGS launcher
|
|
- Better interfaces for other developers to use Legendary in their projects
|
|
- Lots and lots of bug fixes, optimizations, and refactoring...
|
|
|
|
## Requirements
|
|
|
|
- python 3.8+ (64-bit on Windows)
|
|
- requests
|
|
- setuptools (only when installing/building)
|
|
|
|
## How to run/install
|
|
|
|
### Package Manager
|
|
|
|
Some distros already have (unofficial) packages available, check out the [Available Linux Packages](https://github.com/derrod/legendary/wiki/Available-Linux-Packages) wiki page for details.
|
|
|
|
Currently this includes [Arch](https://github.com/derrod/legendary/wiki/Available-Linux-Packages#arch-aur) and [Fedora](https://github.com/derrod/legendary/wiki/Available-Linux-Packages#fedora) but more will be available in the future.
|
|
|
|
### Standalone
|
|
Download the latest `legendary` or `legendary.exe` binary from [the latest release](https://github.com/derrod/legendary/releases/latest)
|
|
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
|
|
|
|
Via PyPI: `pip install legendary-gl`
|
|
|
|
Manually:
|
|
- Install python3.8, setuptools and requests
|
|
- Clone the git repository
|
|
- Run `python3.8 setup.py install`
|
|
|
|
#### Ubuntu 20.04 example
|
|
|
|
Ubuntu 20.04's standard repositories include everything needed to install legendary:
|
|
````bash
|
|
sudo apt install python3 python3-requests python3-setuptools-git
|
|
git clone https://github.com/derrod/legendary.git
|
|
cd legendary
|
|
sudo python3 setup.py install
|
|
````
|
|
|
|
Note that in this example we used `sudo` to install the package on the system, this may not be advisable depending on your setup.
|
|
|
|
### Directly from the repo (for dev/testing)
|
|
|
|
- Install python3.8 and requests (optionally in a venv)
|
|
- cd into `legendary/` (the folder with `cli.py`)
|
|
- run `PYTHONPATH=.. python3.8 cli.py`
|
|
|
|
## 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 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.
