- 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 v7 already features HDTP3 in all but the Navarre lip sync and MJ12 model fix. v8 will feature those too perhaps. I say perhaps because the MJ12 model will interfere with the MJ12 Elite character (which have a unique look to distinguish them from normal MJ12) and the HDTP character models are a general inconsistency anyhow, being that there only 9 or so updated models/skins, so of which with different art styles.

Eh, GMDX's popularity statistics are consistently pathetic for a highly-praised MOTY winner. The masses require marketing efforts at lengths I am not prepared to go to (facebook and such). I'd rather just focus on the mod.

err, as regards your marketing, I would suggest pinging a few streamers / Youtube reviewers as they need content to market their channels. At the least, that effort is easy on your time :)

Hi, just notifying you that this mod is showing up on the home page of Invisible War as well (but not the downloads page). I was going to run through IW just as a diversion and was really excited to see this mod there. But with no download there, I tracked it to over here and now I am disappoint for my IW plans :\

Correct. The popularity has gone up and I hope it will explode when v8 comes out.

need a little guidance

I'm running Deus Ex on my Macbook through Wineskin/winewrapper and I want to install GMDX. The only way to be able to do this it seems is to copy the GMDX files from a folder. I've gotten the install to work now I need to know exactly which files to copy.

I must be missing some because so far I've got the menu to work, as in Hardcore mode shows up as an option, but when I click it nothing happens. Also, there is no Stealth in the skills tree, so it seems I'm still just running the vanilla game.

Help would be appreciated, can't wait to try v7!

Try making the wrapper open the installer and using the installer that way. Then redirect it back to the original executable.

Other wine users have reported no problems, but I don't know how wine works so my help will be limited.

If you're just copying files straight from the GMDX folder into the DeusEx core folders and overwriting vanilla content, then just stick everything in DeusEx\System (except the maps, which would go in DeusEx\Maps) and then launch the game via vanilla means (not the GMDX shortcut), but of course this method will overwrite your vanilla install (nothing a reinstall cannot fix).

Before you decide what to do, check over the Installation Guide: Moddb.com if you haven't already.

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…
