GMDX is an award-winning large-scale modification for the 2000 PC classic Deus Ex. GMDX addresses the many flaws of the game, polishes it to a very high standard, and adds new layers of depth that one would have hoped to see in a sequel. GMDX is executed with the strict parameter of staying true to the original design principles that define Deus Ex, and seeks to improve all aspects of design excluding the plot and soundtrack. The cumulative result thus far is said to be, and aims to be the "definitive Deus Ex experience".

GMDX is a comprehensive "advancement" modification which aims to improve upon almost every aspect of the Deus Ex experience. Gameplay mechanics have been painstakingly tweaked and revised in order to provide far better balance between skills, augmentations, and expendable items. NPC and enemy AI has been altered to behave more realistically than ever before. Meanwhile, each level has been retouched and/or expanded with a number of graphical, decorative, and architectural enhancements which add an extra layer of discovery for veteran DX players. When combined with the New Vision and HDTP mod packages, this “fresh coat of paint” does an outstanding job of remaining faithful to the original artistic vision of Deus Ex while improving the graphical fidelity of the game.

Augmentations, in particular, have been enormously improved. Health Regeneration and Ballistic Resistance no longer throw the difficulty curve out of balance, while the much maligned Aqualung and Microfibral Muscle systems are now significantly more useful and worthy of consideration. Meanwhile, a revamped skills system (which includes new abilities such as Stealth) yields far more variety and actually forces the player to think hard about how to allocate his or her XP.

Throughout it all, the mod manages to preserve the original design principles of Warren Spector and the Ion Storm team while providing much-needed graphical, gameplay, and performance enhancements. This approach manages to breathe brand new life into a 14 year old classic, and I can honestly say that GMDX represents the definitive Deus Ex experience.

A must-play for DX newcomers and veterans alike.
