A Deus Ex Advancement Mod

Gameplay - Audio Design - Bug Patches - Level Design - Graphics

Mod of the Year Awards
Editor's Choice Worldy Award

What if? What if Ion Storm Austin 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 of Ion Storm.
Any developer could keep working on their game post-release in theory, further expanding and refining, but the nature of the game industry demands you move onto your next project.
Ion Storm granted the opportunity to anyone to contribute to the fine game that is Deus Ex. Few have the insight or the dedication to get it right, however...

I am currently seeking animators to improve NPC animations, reload animations and add new sequences.

A new bug. Well, unintended feature? Now that you have a security bot patrolling the perimeter of the Airbase (The mission right after Hell's Kitchen III) he will spot you through the fence, open the fence, and kill you in 5 seconds flat. It makes entering through the main gate nearly impossible. Probably the biggest weakness of the mod so far is it really kills any desire to take anything but the easier path, making the game way more linear. If going through the main gate gets me killed 99% of the time, then obviously the sewers are the only good choice, but since DX is all about lots of choices, that kinda bugs me. Now, if both routes were equally difficult, I wouldn't really be able to complain since, you know, they're equal... but this big gap in risk/reward is kinda immersion breaking IMO.

The bot is patrolling on a rather long route. There is plenty of time to sneak past. > 10 second intervals. And that is without the use of any stealth tools (or just shooting it with Sabot or whatever).
And keep your reports confined to the forum please.

Also, if you're looking for the "best" route, just mantle over the wall and up onto the roof right at the start.
Unbalanced paths was a problem in the vanilla game. I've done a lot in an attempt to solve the problem, but ultimate consistency is just not possible with so many variables at play. Legitimate, fixable issues should be reported, however.

Just a heads up, there's a lot more bugs/suggestions in that thread. Idk if you check those forums a bunch or not, but I didn't get a reply and idk if you got to see them or not. I'm currently almost to the Submarine Base, just finished Hell's Kitchen III.

Take one of the greatest and carry on where the original developers left off. The result should ideally be a new level of art rarely approached.

Some small bugs:

1. The text for hacking says "syphon bank accounts" but it's supposed to be spelled "siphon".
2. There are more than a few completely blank datapads throughout the game. The notable one kept popping up at UNATCO. There's probably way more, I just haven't beaten the game yet.
3. I installed HDTP and etc as per the install instructions, and quite a few surfaces in the game are pure black, they look like a void except shining a flashlight on them does nothing, they stay pure black. I notice them a lot in tunnels... I'd have to replay to remember all the places though. I think it's a missing texture(s?).

I very much appreciate the reports, but know there is a forum specifically for them here: Moddb.com

You can report or request anything you want. Walls of text will be read.

1. Simple.wikipedia.org
2. Intentional. Why would all be written in as a rule? You find blank/unused notepads etc in the real world.
3. A problem with the DX10 renderer. Switch to DX9 or disable multipass Texturing in the renderer settings.

Oh and CyberP, one small suggestion unless you implemented it already... can you make the pistol skill have a similar stacking effect for the PS20 as the environmental skill has for suits? Would be great to get 2 PS20's at trained, 3 at advanced, and infinite at master level pistols.

Yeah, I'll take a look.

One other minor tweak... the Medicine trait still feels kinda weaksauce, it really always did. Maybe the Master level can make Biocells give 35 units of energy instead of 25? Nothing really enhances biocells currently, and that'd be a neat touch.

Possibly. I think the new head & torso health boost is adequate, as well as the poison nullification, yet you're not the first person to request this.

As for the PS20s, if I do it there will be no infinite stacking. But up to four at master level sounds perfectly reasonable.

4 Sounds fine to me too. I just figured given the fact that they're very limited and of all the skills I've seen you always seem to do incremental boosts per level, and then a sudden big boost, that 'unlimited' still isn't very much. There's not even 20 in the whole game, correct me if wrong?

Probably about 30-35 in GMDX as I've added a few more in places.

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 and challenge the player to a far greater degree than ever before. Meanwhile, each level has been retouched and/or expanded with a number of graphical, decorative…
