***Important*** You will need to use sstool to update your game before installing the below mods, especially for the CD version of the game. According to here:
http://www.gog.com/forum/system_shock_2/system_shock2_faq_patches_mods_recommendations/page1 you need to do the following:
latest Directx 9 distribution

-patch up with ss2tool, this will make sure all the files are present in their most recent version (some of the new mods require this, make sure you do it before you start installing mods). just run the tool and point it to your SS2 install, everything else should be done automatically (you need to be connected to the internet, as the tool is a webinstaller). if you want to use the multiplayer, enable it in the options (it's buggy, you have been warned).
Here is a link to the mods that I use for System Shock 2. Some might quibble about Rebirth, and I'm not wild about some of the human models, but this pack is meant to aggregate the many many (Many?) mods that are out there into one, easy to install graphics pack for people who just want to install the mods and get on with it instead of taking an hour of going through threads at Systemshock.org, some of the mods were a bit hidden in the threads. Also, I created NONE of these models, I justed zipped them together to make it convenient for new players to graphically update their game. I was planning to awhile ago, but after I found out SS2 was coming out yesterday, I figured now was the time.
*EDIT* Updated link with newsky in correct directory, rebirth movie ripped from SS2 HD demo (complete cutscene!), and sstool 5,0.

Credits are at the bottom of this post, but first some notes:
First, go into your SS2 install directory and backup the cam_ext.cfg file. The zip includes a modified file that has only been tested with an Nvidia card. It has been modified to max out image quality, and add a little bloom to the game, as well as crop the movies to fill widescreen (there will still be some black bars on the bottom).
Extract sstool from the archive and run it. It should download any files it needs for the update, as long as you have a working internet connection.
Next, unzip the files and drop all of the files in the archive into your System Shock 2 directory.
To run newsky, go to cam.cfg in your System Shock 2 directory and add "enhanced_sky 1" (without the quotes) at the bottom of the file. The newsky folder will be in the base System Shock 2 directory instead of the mod directory, due to how it works, per the author. Also, I added some recommended keybindings from The Somethingawful Forums. Go to settings and controls, and there's an option to load saved keybindings. It will show up there.
One final note: it may be due to how I installed mods, but I never got the Nurse Bloom model to work in my game, even when I put the files int the root directory. I did make an adjustment per Vurt to get his Security Door to work with SHTUP, as the texture looks a little nicer than the SHTUP version.
