It is not a standalone free game package: users still need original or demo Arx Fatalis data. ### Project history The project exists because the Arx Fatalis engine source code was publicly released, while the game data remained proprietary. Arx Libertatis packages and modernizes that engine under GPL 3+ terms, focusing on portability, bug fixes, and compatibility with modern systems. The GitHub repository was created in January 2011. Official releases visible through GitHub include Arx Libertatis 1.2 in July 2021 and 1.2.1 in April 2022, with the website presenting 1.2.1 as the current public release at research time. Official documentation and the FAQ describe the project's goal as updating and improving Arx Fatalis to bring it up to par with modern implementations of similar games. Before the first release, the focus was porting the game and fixing issues with modern operating systems. ### Adoption history Arx Libertatis' adoption is tied to the Arx Fatalis community and to distribution packaging. The website provides official Windows and Linux builds and notes packaging for macOS through Homebrew, FreeBSD, DragonFly BSD, NetBSD, OpenBSD, Haiku, and Pandora. The provided package-manager facts also list Homebrew, dnf, and Nix. Because users must supply original or demo game data, package-manager adoption centers on engine delivery rather than content distribution. The README documents `arx-install-data` for extracting/installing data from CD, demo, GOG.com installers, Steam installs, and other Arx Fatalis installs. ### How it is used A typical user installs the engine, obtains the original or demo Arx Fatalis data, installs or points Arx Libertatis at that data, then runs `arx`. The README also documents `arx --list-dirs`, portable directory options, and tools such as `arx-install-data`, `arxsavetool`, and `arxunpak`. The official paths matter to packagers: Linux splits user data and config between `~/.local/share/arx/` and `~/.config/arx/`, macOS uses `~/Library/Application Support/ArxLibertatis/`, and Windows uses the user's My Games or Saved Games directory depending on OS generation. ### Why package nerds care Arx Libertatis is a classic source-port packaging case. The package ships code and tools, but not copyrighted game assets, so package recipes must handle engine binaries, data search paths, launch wrappers, and user instructions cleanly. It is also a useful comparison point for other open engine reimplementations and ports: portability work, save/data migration, case-sensitive filesystem handling, and preserving compatibility with legacy commercial game data all become packaging concerns. ### Timeline - 2002: Arx Fatalis released, according to the Arx Libertatis website description. - 2011: ArxLibertatis GitHub repository created. - 2021: Arx Libertatis 1.2 release published. - 2022: Arx Libertatis 1.2.1 bugfix release published. ### Related projects - The Arx Libertatis website links to related Arx Fatalis resources and mods, including Arx Insanity, Arx Neuralis, Arx Fatalis UE4 Remastered, Arx End Of Sun, and a wiki page of additional Arx Fatalis mods. The FAQ also compares the idea to OpenMW for Morrowind. ### Sources - - - - - - - source_facts.package-manager ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
