This is the newest release of Narodnaya Solyanka (named "Narodnaya Solyanka 2016" by the developers). Unfortunately for the English Stalker community, the mod is available only in the Russian language.
I'm personally hand-translating the entire mod to English. This means that not only will it be in English, but it will not be some garbled machine-translated nonsense.
On-top of that, included will be a quality third-party weapon pack as well as many other edits (better textures, shaders, etc).
The foundation of the NS storyline has stayed the same, but some things have changed. Many of the quests will seem familiar to you if you've played NS before, but they will have a new twist to them giving a much needed breathe of fresh air into NS. Many of the NS maps have been recompiled in both it's geometry, light maps and AI grids. This has fixed many of the bugs plaguing the older NS branches (out of memory crashes, etc.).
There have been added quest branches to the CoP maps (which you can actually get to unlike some NS variants). Two new maps added onto the normal NS map expansion: Darkscape (taken from Lost Alpha) & Mine (exclusively made for this mod). Scripts have been optimized for fast loading. Secondary task givers are stronger than normal NPCs, but are not immortal. Ability to switch to different HUDs using the in-game menu.
