Catacomb Abyss 3D2016

Following the publication of the Catacomb series on GOG, Flat Rock Software decided to open-source these games under the GPL license in 2014. This enabled programmers to port the source code of Catacomb Abyss to other operating systems. The source port Reflection Keen, later renamed to ReflectionHLE, allows gamers to play Catacomb Abyss on Microsoft Windows, Linux, MacOS, AmigaOS and Android.
