just follow the release notes.txt included in the zip

Also the next links comes in handy.

www.strangebedfellows.de/index.php/topic,8.0.html

This mod increases the poly count of the models and improves their texturing. Suddenly people look like people!

2. The Shock Texture Upgrade Project
www.shtupmod.net/

Or SHTUP for short. This mod improves the textures of many in-game surfaces. Now you can actually read the monitors!

3. DeepFriedBeer's Sound Upgrade for System Shock 2
www.strangebedfellows.de/index.php/topic,27.new.html

This mod replaces many sounds in the game (including all the weapon sounds) with higher-quality, more realistic versions.

In order to manager your mods I highly recommend the System Shock 2 Mod Manager.

Also this site comes in handy especially the shocked toolkit
Because in it is a tool called objtree, which lets you MOD, edit shock2.gam

www.systemshock.org/index.php?board=15.0

Tested the whole stuff mentioned above on windows 7 64 bits
IN 1920x1080 16:9 resolution, and it works flawless

happy gaming
