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 60 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.

Halloween 2014 Missions

September Promotion 1

The Dark Mod community put together a last-minute

"Halloween speed build" contest.

From this effort, one mission "Briarwood Cathedral" by buck28 is currently available to play and a few more missions are due shortly.

I will update this article as the missions become available. As many contributors are going to be late, the deadline will likely be extended per our normal arbitration process.

I cannot update my game. The tdm_update.exe that comes with the "The Dark Mod 2.0 Standalone Full Installer" won't start, it only gives me an error message "tdm_update.exe has stopped working". I tried downloading a different updater from the wiki. It actually starts but it apparently cannot download "" from any mirror and stops updating. Am I just doing something wrong or what's the problem? I couldn't find anyone else with the same problems

Is the folder you have your updater in set to "Read Only"?

Do you have Firewall or Security Software blocking programs from downloading? (if so, you should whitelist the updater)

Thanks, it works now. My folder was read-only, which is funny because I almost never have any folder set as that

Anyway, thanks again

Yeah, I think that something in newer compilers or OS updates is setting this to Read Only by default since we only started seeing this type of problem around TDM 2.0.

Folks having performance issues on the newest AMD\ATI hardware or drivers, please try renaming "TheDarkMod.exe" to "darkathena.exe".

Yeah, the team felt that the balancing for bow vs charging AI was not quite right. The AI have some cover responses but are not good enough to be aware of the danger posed by a bow and players were clearing maps in missions without no-kill objectives. So, until a better solution appears, the workaround is to presume the AI are dodging at the last minute (etc) when alerted. I'll have to find it but we had a rather long discussion about this at the forums. Point of the story, be stealthy and don't provoke AI to make them arrow-fodder. I kinda think a difficulty setting which allows you to kill AI this way would be nice since maps that have good opportunities for the use of broad-head arrows on moving targets are rare and it's a shame that players don't get to experience them more often.

So, since this isn't even a mod anymore, and is fully standalone, were there ever thoughts to put TDM on Steam through Greenlight? I'm not sure it is permited, but I think that as it is a free game, there would be no problems. You're also not using any third party content, besides the engine itself, so there should be no copyright issues.

There's an open discussion on this. Some folks are collecting funds for the entry fee and others are reviewing the Greenlight EULA for legalities.

Here is a discussion, the last I heard Demagogue was coordinating the efforts though (as you will see) this is a contentious subject:

We've got quite a few FOSS warriors in the mix and Valve's pioneering work in getting mainstream acceptance of DRM doesn't sit well with them.

That said, we also have quite a few folks who love the convenience and publicity that Greenlight would give the project.

Greenlight would only increase TDM's exposure, and seeing that this is mainly a community driven/supported project, I believe that the amount of fans developing content for this would increase considerably.

If the problem is really collecting 100 bucks, I bet that everyone in TDM's community would be willing to drop 10 euros/dollars to contribute, at least.
TDM has certainly provided us more entertainment value than that.

Yeah. I don't think the money is as much of a barrier as the license implications it may pose. That said, (personally) these days I can't get my wife to agree to any PC upgrades for gaming purposes or almost any game related funds that aren't for the kids... Don't know if the player-base is in my shoes but I know the a good percentage of the dev team have similar issues (new family responsibilities vs development time and funding)

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.
