Freedoom: a free, retro style, fast-paced FPS - Open source gaming on Linux
Available from https://freedoom.github.io
"The Freedoom project aims to create a complete free content first person shooter game. But Freedoom by itself is just the raw material for a game: it must be paired with a compatible game engine to be played. The download page lists some recommended ones.
"id Software released the source code to their classic game, Doom, under the GNU General Public License. This means that the program code that powers Doom is free; Freedoom complements this with free levels, artwork, sound effects and music to make a completely free game.
"Freedoom is actually three games in one, consisting of two single player campaigns and one set of levels intended for multiplayer deathmatch (FreeDM)." The Freedoom website.

From the Itch.io page: "Initially started as Trijam entry (3h gamejam). Although initially I couldn't think any idea how to use theme portal that wouldn't be taking ideas from game Portal, but in the end I got an idea. So I got involved in it too much because I tried new tools (JuiceFX and Tilesetter) and put in features that brought game out of 3 hour scope. So I kept working on it whole weekend to learn better use of Godot.
"Working on this project I learned how to make extendable game and great deal of solid project development using Godot engine."
