Is there a mod like GMDX (faithfully improves gunplay, AI, graphics, physics and plenty more) for Deus Ex: Invisible War? Or any of the sequels really. That would be amazing.

I don't think there's a larger overhaul such as GMDX available for DE: IW. Did some digging and the only one I can find is this unofficial patch:

Other than that, seems pretty slim selection for mods.

thanks. i was gonna look for that too. now if only someone would patch the bugs in Project Snowblind... well, i don't own the disc of that game anymore.
