GOG release works out of the box, and if you don't want to use the latest mods and don't care about (level) bugfixes, you can use it happily without any additional patching.
voodoo, I have on my HDD a file called 'Ajare + Kolya's Shodan Head.ss2mod' which I downloaded 7 (wow) years ago. I don't believe this was the original filename, and I that renamed it to something so I'd know at a glance what it did. You probably already know what this mod does (if not, it's an upgraded version/texture that's used... well, you can guess where it's used), so I was wondering if you can tell me if it's included in any of the other mods you've linked to. If not, do you (or anyone else here) know where people can download it from? It's a nice little upgrade that I imagine most people would like (hard to post a before and after pic of it in action without it being a spoiler).
it's part of SHTUP now, I think.
