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.

The Story So Far

Just a few months ago, you were a proud sergeant within the military. Your life took a turn for the worst when your convoy ran over a mine and you ended up in the hospital, barely alive. But you're tough, you made it through and recovered eventually. However, when you went back, they told you were no longer fit enough to be in command.

Thanks to your past accomplishments, the military decided to cut you some slack. They referred you to the UAC, a global corporation that is the leader in technology research and currently runs the show on Mars. The UAC is known to have a contract with the military and supplies them with the latest prototype weapons; some of which you've used before. They recently constructed a series of facilities on the outskirts of the desert to "cut down on research costs". Who knows why they built the thing?

You landed yourself a job as a security guard. Driving around the UAC compound 50 times was an usual day's worth of work. You were bored out of your mind and felt that your life has ended at the age of 30... then the incident happened, and your life was once again changed forever.

From out of nowhere, a distress call came from Mars, where the UAC was doing its most shadowy research - Something about demons invading through portals and all sorts of mumbo-jumbo. Mars was apparently under attack by an unknown force and the UAC wasn't ready to lose the red planet for anything. They gathered up a group of the toughest marines and decided to take the place back from whatever attacked them. It was also an opportune time to test out their new gateway system that linked the two planets.

Just as the gateways connected, and the marines were about to go through, a giant spider-like creature stepped through. It ripped the marines and scientists in front of it apart with his two massive auto-cannons while causing massive destruction from what seemed to be a BFG 9000. A horde of strange creatures followed it through the gate and reeked terror on the unsuspecting marines. The creatures quickly took over the gateway control facility and fanned out to the nearby compounds quickly. Many were slain only to have their corpses somehow reanimated.

You were on your 10th loop around the UAC compound when you got radio distress calls for back up. You did what you knew how to do best - kick ass. You fought you way through to the command station to see what was going on.

News of the incident reached out fast and the UAC compound was locked down within a matter of hours. All roads to and from the site were shut off and anyone trying to go in or out was shot on sight. When you made it to the command station, you learned of the gateway and the beasts running through it. You didn't know what to make of it. Then you heard from the military about the quarantine policy and it involved nukes.

You didn't survive the mine just to be killed by army's own nukes now. The only way out was through that gateway. You don't know where it would take you, or if you were even survive long enough to get to it. But anything is better than being turned into radioactive vapor. You gathered all the ammunition you could find and prepared for the fight of your life...

What's New

Demon Eclipse offers a wide range of new material, including a lot of custom graphics new maps, sounds and music, as well as a new Doom experience.

Originally meant to be a custom resource wad, Demon Eclipse has evolved into a large mega-wad project. It features a large arsenal of remade or completely new weapons and monsters.

Weapon Information

Demon Eclipse aims to preserve as much of the original Doom gameplay early on as possible. For this reason, the first episode has the same weapons as the original Doom, with several secret weapons added in later. However, all later weapons from the other episodes are completely new, designed to fit into the environment they were designed for.

  • Episode 1: Doorway of Abaddon weapons are re-sprited versions of the original Doom arsenal. They behave almost identically to the original arsenal with some minor adjustments. Announced by the latest news, several secret weapons - the Auto-Shotgun, the Chaingun (read below) and the Homing-Rocket launcher have been added.
  • Episode 2: Pandemonium Fortress weapons resemble that of Heretic; dark magical weapons found within the Pandemonium Fortress. A "Doom Sphere" (DE version, Skulltag) can "power-up" each weapon, changing their behavior and greatly boosting their power for a limited amount of time. The latest news promises a secret weapon - the Immolator.
  • Episode 3: Planes of Despair weapons are very similar to those in Episode 2. They can be powered up by the Doomsphere. However, in additional to that, each weapon has a unlockable alt-fire mode that can be attained by finding the proper upgrade items for that weapon. More powerful weapons take more parts to unlock their special mode.
Ep # Slot 1 Slot 2 Slot 3 Slot 4 Slot 5 Slot 6 Slot 7 Slot 8
1 Fist, Chainsaw Pistol Shotgun, SuperShotgun, Auto-Shotgun Machine Gun, Chaingun Rocket Launcher, Homing-Rocket Launcher Plasma Rifle BFG9000

Episode Infomation

DE is split into three episodes, each designed to have its own theme. Each episode have 6 normal maps and 1 secret map.

Ep-1: "Doorway to Abaddon"

Episode 1 is where it all begins. Your goal is to fight your way to the gateway before the nukes fall. You don't know where it would take you, but you hope it's mars.


Ep-1 uses the Doom E1 feel, with the green UAC facilities and lots of nukage pools. Episode 1 features no new weapons but does offer three new monsters (Cybruiser, Demolisher, and Annihilator). The goal of Episode 1 was to give the E1 feel of the original Doom while utilizing GZdoom's more advanced features.

List of Maps

  • Map01: "Command Station"
  • Map02: "Waste Processor"
  • Map03: "The Reactor"
  • Map04: "Gateway Control"

  • Map41: "The Refinery" (secret)

Ep-2: "The Pandemonium Fortress"

After you kill the "Core" on Mars during Ep-1, it thrusts you into the abyss before it dies. When you wake up, you find yourself in hell once again. Things couldn't get any worse, could they? Your goal in Episode 2 is to blast through 6 Hellish fortresses and kill the Hellforge smith that lords over it.


DE Ep-2 uses the "hellish fortress" feel, present in many maps of the original Doom's second episode. In Ep-2 you face a large number of new monsters which are much tougher than the ones you're used to in Ep-1. To combat them, a brand-new arsenal of "hell-weapons" are available for you to find. Episode 2 is much harder than Episode 1 in many respects, and is meant for more experienced Doomers. Episode 2 also offers new power-ups and items for the player.

Ep-3: "Planes of Despair"

After killing the Hellsmith in Ep-2, a portal opens for you. You thought it would take you home, but instead it takes you even deeper into the bowels of Hell. You find yourself in a dark temple, of sorts, with 5 portals. You're not sure where each would take you, but you take your chances.


In Ep-3, the player is offered an experience like that of Hexen. The episode is split between 6 maps, linked by the 5 Portals. Each portal takes you to a "plane" of hell where it's a unique world with unique monsters, environments, and other dangers. Like Episode 2, there will be a completely new set of weapons and items. Your goal of this episode is to collect the six parts of the "Unmaker", which would allow you to enter the the inner sanctums.
