I guess I started playing Deus Ex at the right time---after four years of development Deus Ex: New Vision, a graphics mod pack that overhauls the first-person shooter's textures, has been released.
Znokiss---the gamer responsible for gathering all the graphical enhancement mods for Deus Ex---has even updated his "Ultimage Tutorial" for the Steam version of the PC game. The downloads he has supplied includes Deus Ex: New Vision. The tutorials also packages everything so as to be user-friendly; all one has to do is to follow the step-by-step instructions that Znokiss has supplied.
The link to the tutorial---and my own tweaks to the FPS-RPG hybrid---after the jump.
>>>This link leads to the Deus Ex Graphics (Textures) Modification Pack tutorial tutorial. It also contains tweaks that I've added.
