This work is a large addon for the mod New Story 5 (by dan), which brings many additions and changes to the game.
The plot replaces the original one, its action takes place about six months, maybe a year before the original events. Installed on patch 1.0004, if you have Steam or Gog, there is like patch 1.0006. Also, in the file I put a program that will roll back the patch, but before that it will create a bin folder as a backup, i.e. bin_bakup/ And then install stk-back-4, on the Internet, it is called S.T.A.L.K.E.R "Downgrade from 1.006 v. to 1.004.". Then move gamedata.dbn to the folder where the game is located, if it is in Steam, then there is how to view local files. This modification is available only in Russian.
Do you have a link for "New Story 5"?
Sorry, it seems you can download, Yes, this is New Plot 5, Secret Paths, otherwise it was called the Call of the Monolith, but this is not the official name. It is installed through the installer, but you just need to look for the game, with patch 1.0004, I kind of put it in the file so that if you have a license, roll back the files, but make a backup of the files
