Humphries, Matthew (2012年4月21日). “Arx Libertatis: cross-platform port of Arx Fatalis released”. geek.com. 2012年11月17日閲覧。 “What's interesting about Arx Fatalis is that development of the game started up again last year. Arkane Studios released patch 1.21 and with it open-sourced the engine. That led to an new project called Arx Libertatis, which aimed to update the game to be played on multiple modern operating systems including Windows and Linux.”
