This mod (named "Narodnaya Solyanka 2016" by the developers) was developed only in Russian. I've personally hand-translated the mod to English. It also contains a third-party weapon pack, updated textures, shaders, addons and many personal fixes.
Was an interesting way how I ended up with his weapon.
Mod is looking good, nice work!
Does NS2016 fix much of the broken stuff in the original and the JPs? I mean stuff like the somewhat delicate quest chains. I'm looking forward to playing this as my next SoC mod (and Dead Air for CoC/CoM).
I haven't done a playthrough yet, so I can't give you any personal experience on it, but I can say that so far ALOT of the quests have been reworked. Starting even at the very beginning (i.e. the cave sequence is completely different).
There is still, albeit new, guide for the mod. It seems like those later quest chains might still be delicate, as you say, since there are steps involved. However, if it's anything like the beginning of the mod, I would presume to believe that they have at least been reworked and cleaned up.
Another nice thing is the geometry and AI grids have been corrected in the non-vanilla maps. Should fix many of the weird bugs/crashes that happened in the older version when in those maps.
