The Dark Mod

The Dark Mod takes place in a classic gothic steampunk world. This includes a crossover of elements of fantasy, the Late Middle Ages, the Victorian era and the Industrial Revolution. Although set in a very similar world to that of the original Thief series, the mod does not use any of the original Thief intellectual property.[2][3]

The player is an agile thief in a hostile world. He has to use his equipment and the environment to avoid guards, traps, creatures or other threats. His equipment includes a blackjack, water arrows, holy water, flashbombs, mines, and more. Since the player has only a limited fighting capability, he is supposed to sneak and hide in dark, mostly avoiding combat. The plot and mission goals are set by the author of the fan mission or campaign.[2][3]

The Dark Mod was originally released as a total conversion modification for Doom 3, but with the release of version 2.0 it became completely standalone on the id Tech 4 game engine. The game's source code is licensed under the GNU General Public License 3 and all other non-software components are under Creative Commons BY-NC-SA.[1]

The mod was originally developed as a toolkit. It includes models, sounds, AI, art, tools, and a specialised editor for users to create custom missions. The development of the mod started in 2004, and the first Beta was released in 2008, along with its first mission. In October 2009, v 1.0 was released. In October 2013 version 2.0 was released as a standalone game that included two missions created by the development team. The current version is v 2.08,[4] and has over 130 fan-made missions available.

The Dark Mod 2.06 includes code from the dhewm3 fork of the id Tech 4 game engine that was ported to 64-bit, etc.[5] It is now possible to play The Dark Mod as a native 64-bit build on Linux without any 32-bit libraries.
