well, you're in luck of sorts. the same team has another mod called The Nameless Mod. a bit heavy on the download (about 1GB) but it's a whole new story with updated textures and all. you should try that.
Holy kluck, what a great game! I only played it some on release, but I apparently missed out on a great game. On this install though I used this patch + pluss with no problems encountered. Also, the graphics is still top-notch if you override the graphics in the Nvidia Control Panel and enable full antialiasing etc. In addition there's a widescreen patcher included in this patch.
Highly recommended for anyone who's not tried it out.
