Essential improvements

Patches

Unofficial v1.0008 Patch

Compatible with Zone Reclamation Project.

Unofficial patch by "Codebro" that provides some fixes to the renderer and gameplay.

v1.0006

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.[6][7]

v1.0005

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

v1.0004

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.

Downgrading from v1.0006

A guide on how to downgrade a copy of the game to v1.0005 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[8]

Zone Reclamation Project

Keeps the game as vanilla as possible.
Fixes many bugs present in final version of game.
Improved UI and controls.

Xetrill's Modified LuaJIT library

Users have reported increased performance, especially with script-heavy mods.
It can crash some more complex mods like those in the NS/Soup family.

Modifications

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

Notes

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

Notes

  1. This version of StarForce DRM does not work on Windows 8.1, Windows 10, or Windows 11.[1][2] For supported versions of Windows the StarForce driver may need to be updated manually using SFUPDATE.
  2. 2.0 2.1 File/folder structure within this directory reflects the path(s) listed for Windows and/or Steam game data (use Wine regedit to access Windows registry paths). Games with Steam Cloud support may store data in ~/.steam/steam/userdata/<user-id>/4500/ in addition to or instead of this directory. The app ID (4500) may differ in some cases. Treat backslashes as forward slashes. See the glossary page for details.
