The LibreQuake project aims to create a complete, free content first-person shooter game, but LibreQuake by itself is just the raw material for a game. It must be paired with a compatible engine to be played.
There is a massive back catalogue, spanning over two decades, containing thousands of Quake levels and other modifications (“mods”) made by fans of the game. LibreQuake aims to be compatible with these and allows most to be played without the need to use non-free software.
To install mods for the flatpak version of LibreQuake you need to place them in the
~/.var/app/io.github.lavenderdotpet.LibreQuake/.quakespasm/ directory.
This is were your config, screenshots and demos are located too.
Disclaimer: In its current form LibreQuake is a work in progress effort which may include placeholder assets, missing textures or unfinished parts.
This release is bundled with the quakespasm sourceport which is released under the GPL-2.0 license. See the Github page for details about used licenses.
