Arx Libertatis VR (Arx Fatalis)

Overview

Arx Libertatis VR by cmpayc is a fan-made VR version of Arkane Studios' 2002 PC RPG Arx Fatalis, built on Arx Libertatis, the open-source port of the released Arx Fatalis source code. It has a full body, real sword swings (faster, wider swings hit harder), physical shield blocks, a bow you draw by hand, runes you draw in the air to cast spells, and the book and notes held in your hands. Release vr-v0.2.1 adds paying with your purse, eating and drinking by holding food or potions to your mouth, and a faster inventory. Alongside the PCVR build, the release includes a native Quest 3 build (Vulkan, experimental).

Install type: APK + your own game files.

[!IMPORTANT] No game files are included. You need the data files of your own copy of Arx Fatalis (Steam, GOG or CD). The free demo data also works. Fan project, not affiliated with Arkane Studios, Bethesda or Meta.

[!NOTE] Experimental. The Quest version is still being tuned, and the frame rate can drop in heavy scenes. It's tested on Meta Quest 3 and Quest 3S. The Windows zip on the same release page is the PCVR build.

Step-by-Step Installation

1. Install the APK

Download ArxLibertatisVR-0.2.1-android-arm64.apk via 1-click on QuestPorts or from GitHub Releases. Install it with SideQuest (Install APK file from folder) or:

adb install -r ArxLibertatisVR-0.2.1-android-arm64.apk

2. Launch once

Open Library > Unknown Sources > Arx Libertatis VR. The game won't start yet, but it creates the folder /sdcard/ArxLibertatis/ with its config.

3. Copy your game data

Copy the Arx Fatalis data files (data*.pak, sfx.pak, speech*.pak, loc*.pak, and the misc and graph folders) into /sdcard/ArxLibertatis/:

Use SideQuest's file browser, a USB file transfer, or adb push <file or folder> /sdcard/ArxLibertatis/ for each item. The exact .pak names depend on your copy and language.

4. Start the game

Launch it again and allow All files access when asked, then restart the game.
