A Deus Ex Advancement Mod.

What if? What if Ion Storm continued to work on Deus Ex rather than releasing it when they did?
What if it were more uncompromising in it's design? What if it's widely agreed upon flaws were no more?
GMDX may very well be the closest answer. The goal is to expand upon the game whilst strictly staying true to the original design principles.

  • More life-like & challenging AI, in addition to new enemy types.
  • Higher quality weaponry.
  • Improved and balanced RPG systems.
  • Expanded choice & consequence design.
  • Stabilizes Deus Ex's massively declining difficulty curve.
  • Adds an extra optional difficulty mode for those who seek additional challenge.
  • Fixes many bugs.
  • Altered level design in the interest of gameplay balance, choice and consequence design, realism and aesthetic detail.
  • Enhances various visual effects (explosions, gore, projectiles etc).
  • Improved audio design.
  • Many miscellaneous new features.

GMDX In combination with HDTP & New Vision brings you the next logical step for Deus Ex, 14 years since the original game's release. The mod is still in development but it is at a stage adequate to be labelled an "advancement mod". 
We are currently seeking animators to improve NPC animations, reload animations and add new sequences.

- Increased microfibral muscle throw velocity a touch.


- Implemented Rate of Fire mods.
- Weapon mods are now stackable in the inventory.

- Made non-swinging cameras reset view rotation after tagging player (vanila fix)
- Fixed bug that makes carcasses already in a map with a weapon in it's inventory just crap out as it has not got spawned ammotype (vanila fix).

Note to players of GMDX v6.1 ONLY:  this should be fine to install on top of a current playthrough and continue.

This is likely to conclude development of the mod. I may pick it back up again one day.

Ok I'm sure I read this a month ago, but I need to ask and I don't wanna spend time searching please :D

You said something about bugs when you enable HD models and faces for HDTP Beta. What kind of bugs? I really like the HD faces and don't wanna go without them, but if the bugs are bad, I'll skip the faces..

Game is still installing. Damn slow net!! sryy :)

I advise you to try for yourself. Only a few of them are bugged, and MJ12 caused crashing so they are disabled for good.
Nicolette, NSF & UNATCO are the good ones in my opinion, and these have no bugs.

Is anybody having any problems with the latest build?
There's many possible complications and I'd like the mod to be free of them. I require feedback from users with differing hardware and software.

Highest Rated (2 agree) 10/10

I truly think this mod deserves a 10. What it does, it does exceptionally well. The mod makes a number of very cool changes to the base game (with HDTP). First is the overall increase of challenge via various mechanisms such as improved ai, less resources and some nice map alterations. Other very cool features include additional options for role playing at certain parts of the game. There are also conservative (for the sake of balance), but noticeable improvements (in my opinion) to various augmentations…
