Essential improvements



This is the latest official patch for the game. It is best suited for Single Player.


Although this is an official patch, it was recalled by the developers due to the extra bugs it caused. It should only be used to gain the optimal multiplayer experience from the game (most servers use v1.0006). Do NOT install this patch otherwise.
This is the version that Steam and GOG come with.[5][6]


Some mods only work with v1.0004. Only use this patch if those mods have no updated version that work with newer versions of the game.

Unofficial v1.0008 Patch

Unofficial patch, that provides some fixes to the renderer and gameplay.

Downgrading from v.10006

A guide on how to downgrade a copy of the game to v.10005 or v1.0004 can be found in the GOG.com Community Discussions.

The Multi-Patch replaces the GameSpy master servers and optionally forces Vsync. The GOG.com and Steam versions are already patched, however the Steam version of the game still has broken vsync implementation, to fix this go opt-in, in the most recent beta branch.

Skip intro videos

Start game with -nointro parameter[7]

Xetrill's Modified LuaJIT library

Users have reported increased performance, especially with script-heavy mods but it can crash some more complex mods like those in the NS/Soup family.
Use replacement files[citation needed]
  1. Download the modified library.
  2. Extract the content of LuaJIT_EXPERIMENTAL_latest\release\bin in <path-to-game>\bin.[8]

The S.T.A.L.K.E.R. series has garnered a dedicated following which includes a very active modding community, mostly in Russia, however translations are available for most of the popular mods (commonly found in the GSC forums). The best way to determine which type of mods you will enjoy is by first trying the vanilla game (with ZRP for bug fixes). Below are some basic recommendations.
Preparing the game for mods[citation needed]

To use mods with S.T.A.L.K.E.R., you will first need to edit your fsgame.ltx - file found under the installation folder.

  1. Go to the installation folder.
  2. Open fsgame.ltx with a text editor.
  3. Find line:
    $game_data$ = false| true| $fs_root$| gamedata
  4. Change it to:
    $game_data$ = true| true| $fs_root$| gamedata


If the mod comes with an executable, you may need to point it manually to the correct installation folder. If it comes as a file package, extract and copy the mod's contents into your gamedata folder.
To patch your mod or to add new ones on top, overwrite and merge your installation's gamedata folder with the new one.
Using Smart Mod Manager[citation needed]

Download the program at Codeplex. The program installs the mods from .zip or directly from the folder. It will warn you if there are issues with other mods combined; then you have to choose one of them.

  1. First select the game (S.T.A.L.K.E.R.: Shadow of Chernobyl or S.T.A.L.K.E.R.: Clear Sky)
  2. Set up the right language, version and folder of the game
  3. Go to the game tab and install mods from .zip or folder.
Enable/Disable mods also possible in the manager
