Deus Ex: Greasel Edition built for vanilla Deus Ex, read instructions below for install information.
To install:
Extract into Program Files (x86)\Steam\steamapps\common\Deus Ex
Then run the DeusExGreasy.exe in Program Files (x86)\Steam\steamapps\common\Deus Ex\System
it creates the ini file wrong for the DeusExGreasy.exe on my side the fix is to open up the DeusexGreasy.ini afther it makes it then change :
Render=RenderExt.RenderExt
to
Render=Render.Render
then save and you can play
