SHTUP (System Shock 2 Texture Upgrade Project) is a mod for System Shock 2 which aims to increase the resolution of all the common (and quite a few of the not-so-common) object textures. A secondary objective of the mod is to correct all other graphical glitches, such as typos, continuity errors, texture alignment errors, and so on. All of this is to be done while sticking as closely as possible to the original art style. Simply put, our goal is to make SS2 look like a higher-res version of itself.
used this mod and love it, i would definitely recommend this mod to others.
