Help to identify/find the mod (S.T.A.L.K.E.R.: Call of Pripyat)

I watched the video in 2011 like the video was about weapon mod was the location of the swamp in the video, NATO weapons(possibly Solyanka mod) and the main character live in the swamp next to the tree stood drenched some sort of monster (like the librarian animation was normal not rough) wet it/put bullets exactly as much as the battle was going on for like 2 minutes, now it is clear the video does not find, searched. May have deleted it.

It might not be Stalker COP perhaps another version of the game, in General, who can then immediately understand and recognize this mod. (not exactly like the LURK mod which seems to be up to date for 2011)
