Supplice is a total conversion for GZDoom that has been a work-in-progress since 2009~ish. It started out life as a Boom megawad but morphed into a much more ambitious project over the years.
Here is the list of planned features:
- The main campaign will be split into 3 episodes of 10 maps each (plus 1 secret map per episode). Each episode will be made up of two distinct settings for a total 6 different settings. The settings will range from high-tech bases lost in a frozen wasteland, huge weapon factories dotted on a desolate moon, a hellish biotechnical nightmare planet, and so on.
- Maps will range from small to large in size with most being somewhere in-between. Gameplay difficulty will likely be average but harder than the iwad levels. I'm looking for this to be accessible to as many players as possible.
- The core Doom gameplay is being used as a foundation for a slew of new demons, weapons, items, and powerups. Some original things will be tweaked or remixed as well.
- The new arsenal includes 10 weapons. Each weapon has a primary and alternate firing mode. Here's a list of the new weapons:
Spoiler:
- There will be 5 new powerups joining all of the original Doom powerups. Here's a quick list of the powerups:
Spoiler:
- There's a bestiary of about 30 demons, some of which are entirely new and others which are the same Doom demons we know and love (I might go into details on these guys later).
- Tons and tons of new decorations, hazards, obstacles, effects, and items will make an appearance!
- All of the graphics, textures, and sprites are going to be new and/or repainted. This includes an entirely new texture set, new monster sprites, the new weapons, powerups, items, decorations....pretty much new everything! And OpenGL players will get to see extra neat stuff like brightmaps, dynamic lights, and so on.
- There will be an entirely new musical soundtrack by our very talented friend Jimmy!
- Many (if not all) of the sound effects will be replaced (with Bouncy helping out here). There will be lots of sound effects for the new stuff as well.
- Possible extra stuff that may or may not happen:
- A DM map set that will be Zandronum compatible (will depend on Zandronum either coming up to parity with GZDoom OR if we have the free time to craft up the coding work necessary to make the new weapons/powerup/etc work).
- An Eternity-compatible version of the main campaign. This will also depend on how well we can port over the coded behavior aspects from ZScript and the like.
- A weapons-only mod that will let you use the Supplice guns in other map sets.
- A modding resource pack that will contain all of the assets that you can use to make your own maps.
- A Boom/Vanilla version of the resource pack, possibly with slightly enhanced monsters and weapons.
If you have any questions or comments, we will be very happy to answer them

Dev Team:
- Mechadon: Project leader and organizer, main mapper, and lazytron. I’ve also done a good bit with sprites/graphics and some coding.
- Jimmy: Musical wizard, mapper, and general advice giver/helpful person/good friend. He’s been helping me out with the project pretty much from the beginning.
- Cage: Artist extraordinaire. Cage has saved this project from my very mediocre graphic creation skills and has uplifted it to something truly amazing.
- Pillowblaster: DECORATE and coding maestro. Pillowblaster is doing most of the coding-heavy portions of the project.
- Bouncy: Sound effects crafter! Bouncy is making sure that what you'll hear will be new and interesting.
- We will probably have some special guest mappers on board which I'll announce at a later date!
- Also special thanks to Xaser for hosting our development Discord channel.
