The Dark Mod

The Dark Mod — free game, open source, inspired by the game Thief. You act as a professional thief and must perform various tasks.

The background

The first release of the game The Dark Mod was released in 2009. The original game was a mod for Doom 3 and required the presence of the game Doom 3.

In October 2013 released version 2.0, which became independent from Doom 3, but uses the engine id Tech 3. idTech 3 (also known as Doom 3 Engine) is game engine open source, developed by id Software for Doom 3.

A number of major gaming publications did reviews of The Dark Mod. The game received good grades. In 2013, The Dark Mod was awarded “game of the year” from PC Gamer UK.

Distribution and composition

The game is free and is open source. Versions are available for Windows and Linux. There is also the possibility to run the game in MacOS.

In the basic version of The Dark Mod is available 2 training mission that will help you to understand all the aspects of the game.

Additional missions, which are many, can be freely downloaded directly from the game. There are more than 100 different missions. You can see a list of missions, screenshots and their description on the website of the game.

Each mission is a separate map with its design, objects, characters and plot. All the missions made in the same style.


Gameplay takes place in a fictional world. The levels are in a Gothic steampunk style. Cross the Victorian era and the late middle ages, addresses the stage of the industrial revolution.

Stylistically, the levels are similar to levels of the original game Thief and in General the game remains the old atmosphere (who played the Thief, he will understand). It should be understood that The Dark Mod is absolutely independent game, which is neither a continuation nor a fork Thief.

You play as a clever thief who must perform various tasks. We must act discreetly and quietly as possible.

As available tools are used for various items. You can interact with the level objects.

You can walk, run, crawl, Crouch, climb, swing on the ropes. The player must avoid guards and other creatures. The faster you move, the more noise created, and it attracts guards.

The player is available to all kinds of arrows, flash bombs, mines, keys, lock picks, maps, flashlight, telescope, potions and more. Also available a sword and a club.

In each mission you need to perform a certain task or a set of tasks. Jobs can be simple, and can be complex. For example, to find a path from point a to point B, not allowing yourself to discover; to find and steal an object; find the object that contains the necessary information for passing and so on.


Based on The Dark Mod is the engine from Doom 3, so of course, the graphics are already outdated. But the impression of the game it does not spoil.

In the settings you can choose the resolution of the game, adjust the brightness and gamma, turn on vertical sync, set the degree of antialiasing and anisotropic filtering.

In The Dark Mod beautiful texture, lighting effects, shadows, fog and other visual effects. All of this creates a great atmosphere.
