In 2015, during the 15th anniversary of the game's release, Square Enix (who had acquired Eidos earlier) endorsed a free fan-created mod, Deus Ex: Revision which was released through Steam. The mod, created by Caustic Creative, is a graphical overhaul of the original game, adding in support for newer versions of DirectX, improving the textures and the soundtrack from the original game, and adding in more world-building aesthetics.[77]
