The mod was made by Off Topic Productions and released in 2009 after 7 years of development. The mod is very similar to Deus Ex in that it uses the same world textures, the same character models (though all are retextured), and the same multiple-solution gameplay that has made Deus Ex popular. At the same time, The Nameless Mod introduces an entirely new setting, a new story, characters, and several new items, weapons, and enemies. The game is not set in the Deus Ex Universe.
