- Pickups and decorative objects now move when taking damage, meaning explosions send objects flying, hitting objects or shooting them knocks them around.
- Force is transferred when one object hits another.
- AI are knocked back by high-powered weaponry.
- Pool ball physics improved.


- New weapon mods: damage & fully-automatic firing modes.
- Added a "Installed Modifications" display to weapon inventory descriptions. This shows all the weapon mods you have installed with clarity.
- Also updated and improved general weapon information information, such as whether a weapon is semi-automatic or fully-automatic..
- Installing weapon mods produces various different sounds based on type.
- More weapons accept more types of mods.


- Bigger & better than before, GMDX expands upon Deus Ex's level design in every respect whilst staying true to the original style.
- Every map has received attention, improving all aspects of gameplay, enhancing level audio design with ambiance and scripted audio, making things look prettier and more detailed, improving mission scripting and adding more noteworthy places to explore.
- The example image you see below is an overhead shot of a beautiful expansion to the Paris Metro HUB map, where on one side of the map you had the hostel, the bakery, the club and such, but on the other side there was very little at all. On this side you'll have to avoid or take out MJ12 troopers on their patrols by sticking to the side alleys or climbing on the roofs, and you'll find a number of interesting areas to explore.


- AI in GMDX v7.0 are polished to a very high standard, but there's always more you can do. So in GMDX v8.0 we have some finishing touches. Examples:


- Some high-level AI use new augmentations, such as a typhoon-like aug, and visual shielding.
- Improved AI's GMDX camping behavior; behavior when taking cover and holding their positions.
- Optimized AI shooting/aiming behavior primarily related to projectile attacks.


- If an alarm is sounded more enemies are called in (high security areas only).
- Dogs chase and attack the player more effectively, and when they spot you they bark loads and alert nearby AI to your presence. (in other words, they behave closer to real life guard dogs).


- Whilst AI death animation is playing there is no longer invisible collision that blocks bullets and enemy decision-making algorithms.
- A focus on making AI/the game a little easier on lower difficulty levels.
- EMP damage causes an augmented MIB's augmentations to malfunction.
- Yet more appropriate variation in pain, death and knockout sounds.
- Blowing up NPCs doesn't destroy their inventories (Credit: Yuki of Shifter).
- If a military bot stomps over a corpse the corpse will gib.



- Deus Ex at this point in time (GMDX v8.0 milestone) now features over 200 new sounds, resulting in a much-needed audio design overhaul.
- New interactivity sounds, the HUD alerts you audibly when biolectricity is low, an extra focus on level audio design (ambiance, scripted sounds) this time around, plenty new player and AI sounds and much more.


- further gore expansions, such as AI head decapitation, improved blood effects and general polish.
- Many other effects such as augmentation activation effects, weapon and explosion effects, player movement-based effects and of course, much, much more.

That's enough show & tell. The full changelog will be available upon release.

GMDX is shaping up to be a significant achievement in terms of game design, as well as a personal accomplishment. GMDXv8.0 will be the final release of the mod, and additional contributors are sought before that time:

- Heavy-duty testing will be required.
- An animator would be fulfilling as new animations & behavior such as first person takedowns, a greater variation in AI death animations, mantling animations and new anims for the objects that were left behind by Ion Storm.
- Any skill is up for consideration. If you're talented, I'm listening.

Thank you to those that have contributed to GMDX in the past.

GMDX v8.0 will feature accessibility for newcomers. In the original game the chosen difficulty level only changed bullet damage the player received. Now difficulty levels influence stealth, exploration & combat in numerous appropriate ways.

Wow CyberP you have really gotten a long way since your first release! I really like your attention to detail and your new features. The small changes in the maps are well done as well. This is turning into a must have for DX. The game play is way more entertaining. Please consider making a compatibility mode for Revision when it gets released! :)

Hey, I just wanted to bring up the kind-of-huge 'investment bonus' weighting of skill benefits toward their capstone and ask about what kind of gameplay they promote. Designers sometimes forget that 'generalist' is a possible playstyle and I guess I just wanted to know if you've thought about it, whether it's hidden benefit that I failed to see, a decision to discourage that playstyle, or whatever.

Not a criticism (no bad answers one way or another, it's not a crime to leave one of 100 options uncovered), just curious on what your approach to modifying Deus Ex's playstyle systems is.

From the website? "Investment bonus" is perhaps bad wording on my part, which I'll change. It is vanilla design. The more you invest in a particular skill, the greater the rewards, for example the pistol skill grants +5% accuracy, damage and reload speed at trained. +25% at advanced. +100% at master. Exponential growth upon investment. I've just changed some more skills to be similar and sharper in growth, like lockpicking, to make the skill actually worth taking to master. Lockpicking in v8.0 of GMDX is 5%, 10%, 20%, 50%, then 100% if you take the "locksport" perk which first requires you to take the skill to master to be able to purchase.

Hello Cyber P, first of all i'd like to thank you for your work and your dedication.
I played Gmdx and it's a great mod even though it's not perfect but it's still in my top3.
With that being said i have an "assertion failed" message when i leave unatco to hong kong.

I think the error is related to the Deus Exe Launcher rather than GMDX. Try using the original DeusEx.exe file (you backed up the file right?) and see if it works.

GarrLeone Sep 9 2015 replied:

I tried to launch it with DeusExe.exe but the game works without the mods. I can't even check if i can reach Hong Kong because this launcher isn't related to my Gmdx save files.

I mean, the only way for me to launch the mod is with the gmdx shortcut on the desk.

Can you post the contents of your DeusEx.log file here please: Moddb.com

DeusEx.log is a text file which can be found in MyDocuments\DeusEx\System.

Also bear in mind that GMDX is still in development. I aim for "perfection", and getting to the bottom of problems like this will help achieve that.

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…
