Diabolus Ex

Diabolus Ex is a single-level PWAD for Doom II and the GZDoom source port. It was created by Arvydas Brazdeikis (Arvell) and was released on the Doomworld forums on July 7, 2018. Heavily influenced by the  franchise, the map utilizes a custom texture set to portray a dystopic corporation run by the forces of hell. The map uses the custom music track "Diabolus Ex" by El-Metallico.
