Demon Eclipse is a Doom II mod for GZDoom currently being worked on by Eriance. The original vision of Demon Eclipse was supposed to be thru the eyes of another marine during the events of Doom. It was then expanded to include 2 extra episodes, one gothic and another surreal visions of Hell. The overly ambitious project has since been dramatically cut back. The current version is known as Demon Eclipse: Hell-Forged Edition, or simply Hell-Forged.
