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.

The Dark Mod 2.04 is out!

The original plan for The Dark Mod 2.04 was very ambitious.

No fewer than 4 large skunk-works projects were put into motion to bring about massive changes in the game\engine and produce oft-requested features and content. In addition, our community donated massive amounts of textures, models, prefabs, sounds, etc. during the development cycle. All of this increased workload arrived around the time that the core developers were less able to dedicate their free time to the project.

As the 1 year mark from the 2.03 launch approached it was decided that too many critical code fixes and refinements were being kept from players while these gargantuan projects lumbered slowly towards completion. Parallel to this sequence of events, Grayman broke his own vow to take a hiatus from coding (to work in the William Steele missions) and decided to address some issues found with coordinated AI searching in 2.03. Because untangling the assets added for some of the unfinished projects would be a project in itself, it was decided that 2.04 would primarily be a code fix release with only a few assets to go along with renderer fixes.

If you’ve been following along in the forums, you’ll no doubt be aware of a few patch executables that were floating around. These were in one way or another previews of 2.04 with the most commonly downloaded one called the “De-Clunking patch” or “De-Clunking mod”. A full changelog can be found Here.

Better Coordinated Searching:

The changes in 2.03 caused AI to develop a choke-off pattern to more accurately reflect how people in groups would coordinate a search effort. It was found that this change often caused AI to remain stationary around the last known whereabouts of the player (causing the player to wait endlessly for the cool-down process). 2.04 now prompts isolated AI to move around more and investigate hiding spots within a radius of the alert region. This will give players more opportunities to make daring escapes or maneuverability to better reach a point of advantage to the AI.

AI now noticed dropped weapons!

Even the TDM team developers were surprised to find that no prior release had code support for AI noticing dropped weapons. This has been added so now all your weapon hiding antics are meaningful as expected!

Grid Based Inventory option:
We were fortunate to gain a new mouse navigated grid-based inventory manager thanks to a new forum contributor, Durandall.Thank you! To activate, bind a key to _impulse30 in the console or Darkmod.cfg. For example -

  • bind t _impulse30

Pickup up stuff without clunking:

In previous TDM versions, players would often create unintentional alerts by clunking candles, bowls, or other moveables against the table-top when trying to lift them. This became so frustrating that Sotha and Goldwell began using stationary snuff-able candles in their missions to avoid this scenario. Now the grabber more smoothly moves objects into manipulation range and with a middle-click centers them on the screen directly in front of the player for easier manipulation.

Improved Breakables:

While developing breakable display cases for an upcoming mission, it was discovered that the whole breakable system was in poor shape. Crack decals would disappear after a small amount of time, rotated models would spawn pre-fractured, objects thrown through glass with zero-health would simply pass through without shattering it, and the fracture code itself caused a memory leak and save-game crash. SteveL spent a great deal of time sorting out these problems and updated the glass shader rendering as well.

Better looking Glass:

Along with SteveLs rendering fixes, AluminumHaste repaired or improved many of the stained-glass materials. Finally, I (nbohr1more) improved the flask glass shader (using fixes discovered by Obstortte and Arcturus).

Decal Fixes :

One of the oft-mentioned visual annoyances has been decals that seem to pop over distant objects rather than staying on their associated surface. This was tracked to OpenGL depth offset range behavior. It seems that Doom 3 has this set to an absurd 600 units (probably to work with DepthHack particles, which are a precursor to soft-particles in modern engines). 2.04 changes this range to reduce or eliminate this problematic behavior. This will also reduce the likeliness of z-fighting in missions and save on some overdraw.

Quicksave Backups:

A new quicksave safety system has been implemented. Save files are now written with alternating filenames rather than repeatedly overwriting the existing file. For a variety of reasons, the host OS has run into problems with rapid requests to write and overwrite these files leading to either corrupt or lost saves. The new system should be far less prone to this. It currently alternates between two files but can be set to any number you prefer with the com_numSaveGames console argument.

Improved Load Times:

While not a huge jump, it was found that particle bounds were determined via a lengthy Monte Carlo simulation. This has been scaled back to a simpler bounds calculation resulting in shorter map loading.

Sound Fixes:

Sound values are now prevented from being sent to the audio device with negative volume (invalid values) causing popping sounds. A new override system allows mappers to replace the ambient sound easily with another sound of their choice.

Russian & Romanian language improvements:

Thanks to the hard work from folks at the Darkfate Community, we now have better Russian translation and fonts.Similarly, the Romanian translation has been fixed to remove characters which do not have associated fonts yet for a more legible Romanian interface.


For the past few releases, freyk has been creating a GUI installer tool to assist users who are not good with portable file setup in Windows or address dependency issues in Linux. We are now adding this tool to the official installation page as an alternate option.

Bug Fixes:

As with any release, general bug fixes have been addressed. Of major note is the Card Player savegame crash, breakable savegame crash, AI scooting themselves out into the void, and a fix for a memory leak in the SEED system. Logspam has been significantly reduced in both the LOD\SEED system and in DMAP compiling leading to dramatic performance improvement in the latter.

As with all TDM releases, savegames from previous releases are not compatible with the latest release. Please finish you current mission before upgrading or you'll have to start over again.

Hot on the heels of 3 stellar mission releases

another shockingly professional mission arrives from new author Kingsal!

This one has the top Thief communities (The Dark Mod, TTLG, Darkfate) speculating that Kingsal is a professional level designer who decided to grace us with his work. However we were blessed by this creation, the players are certainly appreciative of it.

Penny Dreadful 3: Erasing the Trail

PD3 for 2.04

Melan and Bikerdude have teamed-up to release the (hotly anticipated) 3rd installment of the Penny Dreadful series.

It's a sprawling city mission that rivals or possibly exceeds the enormous "Crucible of Omens: Behind Closed Doors" in size and scope. If you are a roof-top junkie this is the mission for you.

The Smiling Cutpurse

Smiling Cutpurse

A sad note. It seems that our promising new author Airship Ballet has decided to retire from mission creation. This last release was overlooked in the wake of the Crucible of Omens announcement but it's a great little mission with Airship Ballet's typical penchant for clever game-play design. Hopefully we can lure her back for at least one more mission release but the body of her mission work and her asset contributions do not go unnoticed! Cheers to Airship Ballet wherever she has gone!

Mother Rose

Mother Rose

Originally intended for the Halloween Speed-build contest, this overdue mission was completed in January by none other than our lead coder and the author of the outstanding William Steele series Grayman.

We hope that all contestants stick with their mission releases even if they are tardy!

A genuinely scary mission that has all the quality hallmarks you've come to expect from Grayman in a snack sized play-through.


One of our community members (BucleBean) figured-out how to get TDM working in VR. You'll need a fairly strong system for this to be enjoyable but the dream is alive:

Perhaps someday, the VR work done in a few of the Doom 3 forks will get merged and we'll have native VR support?

HRTF Positional Audio

Another community member (Hiradur) found that better positional audio is possible with a new OpenAL wrapper:

EAX for all

Not content just being an awesome voice actor and mission author, Goldwell decided to look into getting EAX working for all users. We are working on a 64-bit build with an Open Source replacement for EAX but in the interim, here's an option for all you EAX reverb junkies:

Thanks Goldwell!

How do I change the Sound from Stereo to Surround? I know I've already got EAX on, but then just to make sure that 3D audio is working I'd like to know how to do it, since my system has support for Surround Sound. Is it because I need 7.1 or 5.1 headphones?

Hi guys! You can tell me something about the guy who wrote the soundtrack for the game? I was very impressed of main theme, and I heard that he worked on names Schatten.

Can't you merge the patches with the main archive, or at least make ONE patch that supercedes its previous versions? Having to install 3 successive patches is not very user friendly. I haven't seen this patching method in at least a decade!

Reply Good karma Bad karma+1 vote

The patches are very small in size, so if you are willing to install them one by one there should be no problem

There will be steam release of standalone through Steam Greenlight? I will vote up for this

most likely never.
