The main album is presented as one side of a dualdisc, while the DVD side features the third part of an extended documentary titled The Pathologist's Report Part III: Mass Infection, and a 23-minute interview with Walker and Amott from 1993, recorded on the Gods of Grind tour.

Ken Owen and Jeff Walker said during The Pathologist's Report Part III: Mass Infection that they rejected the descriptions of Carcass's music on this album being grindcore.

While Owen acknowledges its death metal characteristics, both he and Walker expressed that they are more inclined towards calling their music on this album "progressive".

[4] AllMusic gave Necroticism four out of five stars, stating that the worthy addition of Michael Amott made the record an excellent guitarist's album.
