To help celebrate the 15th anniversary of Deus Ex, Square Enix and Eidos Montreal have "authorised" a fan-made mod for the original game by Caustic Creative that gives the classic game a visual and audio overhaul.

“Revision is a complete overhaul of the original Deus Ex. We bring in new level design, new music, and new world-building detail. On top of that, we also bundle in some of the best enhancements the community has to offer: high-detail textures and models, Direct3D 9 rendering, and alternate gameplay modes. Revision is our love letter to the game and its fans,” said John French, Creative Director, Caustic Creative.

“One of the reasons that Deus Ex has been so popular for 15 years is the way in which the gaming community has embraced the ground-breaking gameplay and a narrative that looks to the future but is inspired by real-world events,” said David Anfossi, Head of Studio, Eidos-Montréal. “‘Revision’ from Caustic Creative is a fantastic way for fans new and old to experience the original Deus Ex in a whole new way before Deus Ex: Mankind Divided® raises the bar once again.”

You can grab the mod from Steam for free today, and be sure to check out the launch trailer embedded below.
