FAQ:
Will this come to forge?
Perhaps, depending on demand and once ported to other versions first.Currently it will work for forge using Sintra Connector.
Other Versions?
Support for more versions is planned and will be done at some point in the future.I cant hear the music?
Threat music is currently tied to the "Players" volume slider, but this may change in the future. Region ambient music is tied to the normal music slider, and if turned off will result in no ambient music.
