[citation needed] A deluxe 30th anniversary box set of Scumdogs was released in August 2020, with remixed and remastered audio by producer Ronan Chris Murphy, as well as an exclusive cassette containing rehearsal demos and previously unreleased tracks.

[3] Those that pre-ordered the box set received a digital download of the remastered album on August 7, 2020, with the first single, "Maggots", being made publicly available the same day.

This is the first Gwar album on which more than two people sing lead (Hell-O had Oderus Urungus and Techno Destructo): "Slaughterama" features Sleazy P. Martini, Sexecutioner sings his namesake song, and the album's CD exclusive closer, "Cool Place To Park", debuts bassist Beefcake the Mighty as a vocalist.

Danielle Stampe (Slymenstra Hymen), Michael Derks (Balsac the Jaws of Death), Chuck Varga (Sexecutioner), and Brad Roberts (Jizmak Da Gusha) make their debuts on this album.

In 2016, Scumdogs of the Universe was ranked #90 on Loudwire's Top 90 Hard Rock + Metal Albums of the 1990s lists.
