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.
Finally got ahold of one of my favorite weapons, an APS.
One of my faves too, cheap to feed.
My life-saver. IMO, the best handgun in STALKER. Just to add a collimator...
