A video was made for "Secular Haze". It was shot in the band's home town of Linköping and directed by Amir Chamdin.

Another video was made for "Year Zero", once again directed by Amir Chamdin. It was unveiled on March 25th, 2013.

Disc printing plants in United States reportedly refused to print the CD artwork depicting forest nymph orgy with inverted crucifix. The latter was deemed "too sacrilegious". The art was done by Polish artist Zbignew Bielak II. The controversial art can still be found on both the vinyl and European copies of the Infestissumam. The said artwork can be viewed here.
This caused the U.S. release to be delayed to April 16th, 2013.
