The Lucid Launcher is your gateway to the game. It lets you install and update the game, browse and enable mods, load community scenarios, and keep everything in sync.
Linux (Arch / rolling-release distros): if the launcher fails with an EGL error, install webkit2gtk-4.1, then run:
LUCID_SYSTEM_LIBS=1 ./Lucid-Launcher.AppImage
