The cover art for Agorapocalypse was drawn by German illustrator Florian Bertmer, who had previously designed the covers for ANb's Bestial Machinery (Discography Volume 1), Agoraphobic Nosebleed / Kill the Client and the inner-sleeve illustration for the group's 1999 split with Converge, The Poacher Diaries.

[3] Bertmer, vocalist J. Randall, and guitarist Scott Hull discussed the themes of the album art by phone and agreed to give it an "old-school thrashcore vibe", because of ANb's new musical direction.

Agorapocalypse's design was also inspired by the Mad Marc Rude illustration for the Misfits' Earth A.D., which Bertmer defined as "insanely detailed".

[5] According to Nielsen SoundScan, Agorapocalypse sold around 1,300 copies in the United States in its first week of release, and peaked at number 41 on the Billboard's Top Heatseekers chart.
