Stealth Gaming in a Gothic Steampunk World

** The Dark Mod wins PC Gamer's 2013 Mod of the Year award! **

“It’s a tremendous achievement – a detailed tribute to the Thief series…. Projects like The Dark Mod are a way for those fans to say “if you won’t make it, we will” – to deftly lift what was good and meaningful about the games that inspired us years ago and run away with it.”
PC Gamer

“this is splendid….it’s basically Thief…but in Doom 3.”
–Rock, Paper, Shotgun

THE DARK MOD was once total conversion of Doom 3, and now is a STANDALONE GAME with the release of TDM 2.0!

A dark and moody stealth game, inspired by the "Thief" series by Looking Glass Studios, The Dark Mod includes creative new gameplay features, dozens of unique AI, and a complete set of custom art assets, allowing players and mappers alike to enjoy missions in a gothic steampunk universe. When you play The Dark Mod, you feel like you’re playing a gothic stealth game…there’s nothing left that’s recognizable from Doom 3.

This game is first and foremost a toolkit, allowing fans and team-members to create their own stealth missions in a gothic steampunk environment. But there are already over 80 full missions for download, including some small campaigns, so it certainly feels like a game. The only difference is that you have to choose which missions to install and play.


The Dark Mod world can be viewed as an alternate version of our own. It is a mixture of several historical periods, with architecture ranging from medieval castles to Victorian mansions. In this world, steam and clockwork technology were discovered much earlier in history, allowing for odd inventions and industrial warehouses to exist side-by-side with Gothic cathedrals and sword-wielding city watch.

We also maintain our own mission editor, called Dark Radiant. It is an updated version of GTKRadiant, and has a lot new features (Python scripting support, many bug-fixes, new Particle preview, Texture Tool etc.) and comes with a number of Dark Mod related plug-ins like an Objectives or Conversation editor.

Announcing the new The Dark Mod 2.03 update!

Ulysses: Genesis Images

The team at Broken Glass Studios is very pleased to announce the latest update to TDM!
The update to 2.03 adds nearly nine months of new assets, features, and bugfixes. Some changes will be noticeable right away, while others will take a while to appear in new maps.
To apply the update, simply run the tdm_update.exe file in your darkmod folder. (Note that saved games from earlier versions will not be compatible with 2.03, so finish any missions you are playing first).
Some of the improvements are listed below. To see the full changelog, go here.

AI changes: AI have a few new animations, including a new pickpocket reaction. Many AI, including the citywatch and builder models, should look more detailed, as most AI are now using LOD (Level of Detail) stages, allowing greater detail up close and less detail (and less of a performance hit) when further away. In terms of behaviour, AI will now coordinate their searches more intelligently when in groups, sending some AI to guard doors and choke-points rather than stepping all over each other. AI will now react when getting hit by an opening door. An issue that allowed AI to see behind them if their head was turned a certain way has been fixed.

Graphics: Particle effects have been greatly improved, so that they no longer create hard lines when intersecting geometry. Water no longer distorts things that are in front of it, and the skybox will no longer flash grey when the player is mantling. The spyglass will now appear round regardless of the screen dimensions used. A number of entities are now using LOD (Level of Detail) stages. You may wish to adjust this option in the Graphics Menu if you see noticeable ‘popping’ of models.

Revelator, a veteran in the Doom 3 mod scene, stepped in to help our new engine coder SteveL with some of the code needed to gain access to the depth buffer. We hope to continue our partnership with this crafty fellow.

Assets: More than a hundred new high-quality textures and models have been added to the game, and should start appearing in new maps. A number of existing models have been improved by adding more polys and better textures. A new female townsfolk model and vocal set has also been added to the game and should start appearing in new maps soon.

A video preview of some of the new features can be viewed below:

Overall, you should notice a distinct improvement to the graphics and AI behaviour in maps. And we have some exciting renderer developments in the pipeline, though that will have to wait for the next update.

Since v2.02 several stellar missions have been released including:

Melan's "Penny Dreadful 2: All the way up"
Sotha's "Ulysses: Genesis"
Goldwell's "Lord Edgar's Bathhouse"
Airship Ballet's "La Banque Bienveillante" and "Chase Mercantile" (parts of the Quinn Co. campaign)

Is this compatible with 1.3.1?

Edit: Nevermind. Just read this on

"Q: What do I need in order to play?

A: Other than TDM itself, you must have a copy of Doom 3. TDM works with the steam version of Doom 3 if you can't find one locally. You must also have the most recent D3 patch."

Hey slytrigger,
Please post a little thread over on our support forum ( and we can look at sorting this out :)
Otherwise check our wiki FAQ/Install instructions and make sure you're using the right patch etc.

And on a side note, 1.03 is on track with many new changes/additions ;)

Hi, I'm a big fan of the Thief series and I must say that I'm mighty impressed with what you guys have cooked up.

I'm using tdm_update.exe right now to update my game to version 1.02 from 1.00. It's running at 20kb/s at most for all the files from different sources. Is there any way for you guys to upload any future patches somewhere else (say, right here)? It'll be mighty fine as the wait from playing all these incredible looking FMs is KILLING me.

Hey there dualshock,

If you could please make a thread over on the TDM forums with more details, we're aware of a few crashes that have been patched for 1.03. But it's always of interest to have more details of vague cases :)

hey snakedog,

We're happy to help you with problems, TDM have a tech support forum on the site and it's recommended to use that. (I'd post a link but newbie accounts cant). Please also use the official forums for any feedback and such as it's much easier to reply to etc and the team reads everything there :)

However make sure you read the wiki/FAQ which covers quite a few problems that are out of our hands. It's likely that you need to drop your interaction shader quality (in the graphics menu) to fix that(Its a problem with geforce 6xxx's iirc). If that fails please make a thread in the support forum and try include a screenshot :)

Great mod, must play for all thief fans. Contains great, userfriendly editor (To tell the truth, this mod is mainly the editor, and fans are making FMsú and a lot of super missions. Try it and you will be surprised.
