The Zone Reclamation Project is an ongoing community-supported bug fix mod for the game "S.T.A.L.K.E.R. - Shadow of Chernobyl" by GSC GameWorld, based on bardak's bug fix attempt for 1.0004. All released ZRP versions since 1.04c work with patches 1.0004, 1.0005 and 1.0006. For more details, see the ZRP FAQ.

Despite the fixes, you can still have crashes. See Crashes Still in the Patched Game to resolve them. For general setup issues (especially for the Steam version) see the Troubleshooting FAQ. For details of which bugs are fixed in the different versions, see Bugs in STALKER.

ZRP 1.09 XR3a (XR is for experimental release) is available here (6.2 MB, 7-Zip* file) for those who would like to help test or simply get a taste of an upcoming release. This is a snapshot of a work in progress. The Modifier is currently unchanged from ZRP 1.07 R5RC, so the same MD5 checksum applies (see below). Details on what's new are posted on this page and this page of the ZRP thread at the GSC forum. Details in the archive for now. ZRP 1.09 uses the same language support as ZRP 1.07 (q.v., below).

Note: Limiting your framerate to 250 fps or less is strongly recommended.

ZRP 1.07 R5 RC is the current official stable release of the ZRP. While very "vanilla", the ZRP patch-mod includes a lot of flexible options and mini-mods (almost all are optional, most are not default). New game highly recommended but not required if you were playing pure vanilla or pure ZRP. ZRP 1.07 even adds free play to vanilla saves. Note that the NPC difficulty settings in 1.07's Modifier are not that useful -- see ZRP 1.09 for updated settings based on newer info. The ZRP 1.07 actor.ltx difficulty settings only apply to explosives; use novice setting in config\defines.ltx for NPCs.

Note: Limiting your framerate to 250 fps or less is strongly recommended.

ZRP-Specific Mini-Mods

The following mod(s) require ZRP 1.07 or later, or a mod based on ZRP, to work with STALKER SoC.

August 21, 2020  --  A ZRP replacement all.spawn file (version 1.1, 1.2 MB) provides an alternative vanilla-like all.spawn for the returning player. It features a few surprises and rewards for the intrepid explorer. The typical player probably won't notice any difference from vanilla until the final level on one of the good-ending paths. This version features the elimination of that lag component caused by stash contents for less hitching during gameplay.

Non-ZRP-Specific Mini-Mods

The following mods do not require any version of the ZRP to work with STALKER SoC. Other than the SoC Sound Fixes file, they are already included in ZRP 1.07 or later.

May 1, 2012  --  SoC Sound Fixes 1.0 (299 KB) corrects those clicks/pops in the boar's death cry, the pseudodog's whine, and the opening of door lockers. It also removes the repeated section of Ghost's PDA recording. Drag-drop install; no fsgame.ltx edit needed. The archive requires 7-Zip or a compatible file extractor.

March 11, 2012  --  A vanilla replacement ZRP Icon Equipment image file 1.1 (356 KB) provides support for four different mini-mods at once: the ABC Sleeping Bag mod, Decane's Quest Overhaul mod, Save's Carry Mod, and NatVac's Artifact Swap mini-mod. Note that this is not for use with big mods or specialty gun mods, which have their own version. This updated version requires 7-Zip or a compatible file extractor.

August 2, 2010  --  Respawn Population Management 1.0 by NatVac (39 KB) adds persistence to save games and some respawn delay randomization to help spread out the replacement respawns of Alife in the game. Works with patches 1.0001 through 1.0006 to fix a vanilla bug. New game not required, but please make a named save before installing as this changes future saves. ZRP not required, but a Modifier configuration file is included. This version is NOT FOR USE with ZRP; an improved version of RPM is already in ZRP 1.07 or later.

December 4, 2008  --  A replacement Rostok image file and config file pair (352 KB) fixes the Rostok minimap when near the level changer to the Bar as well as tweaking the appearance of the locations and size of the underground levels in your PDA. This fix does not require the ZRP and you don't have to start a new game.

October 1, 2008  --  You can try EggChen's Fire Tweak particle effects file (200 KB) to see if it reduces lag when looking at campfires or teleport effects. This replaces the vanilla version -- do not use this if you are already using EggChen's Particle Enhancement mod.

Shadow of Chernobyl Patcher/Unpacker/Packer

For modders and serious tweakers: The Shadow of Chernobyl Patcher/Unpacker/Packer (SoCPUP) is a subset of bardak's X-ray asset converter toolset, specifically the database unpacker and packer portion, adapted by NatVac with support for batch files and extended to include a rudimentary file patcher. Meant to be run in a DOS command prompt shell or in batch files, SoCPUP can be used to extract files from the gamedata database archives (gamedata.dbn) for use in mods and bug fixes. Source included.

Functions and features:

ShoC Treatment 1.0 Half of STALKER SoC's scripts are not used by the game, but many are still processed and occupy memory during gameplay. ShoC_Treatment is a set of instructions and replacement script files compiled by NatVac intended to improve game performance after installation via SocPUP. You will need to do a bit of directory moving in this 1.0 release.
265 KB
SoC Script Fixes 1.0 This is the drag-drop installation version of the ShoC_Treatment script set, pre-packed for North American/Worldwide versions of SoC patched to 1.0004 or later. (CIS users can extract the files from the gamedata.dbb_scripts archive and repack for their own setup.) This should work with any mod as well as improve vanilla operation. No need for fsgame.ltx changes.
2 KB
SEVA Suit Texture Fix This patchfile can extract and patch the SEVA suit to correct wrong texturing when viewed in third-person. Based on a fix by MrSeyker. For use with SoCPUP.

S.T.A.L.K.E.R. Sound Attribute Viewer and Tweaker

For sound modders: The S.T.A.L.K.E.R. Sound Attribute Viewer and Tweaker (SAVandT) by NatVac is a simple program that can reduce the work needed to view and/or edit STALKER sound file attributes used by all three STALKER games to determine initial volume, volume drop-off, and sensitivity of NPCs to the sounds.

Features include:

1.0 MD5 checksum: cb1d266232703c3168f557676192178e *SAVandT.exe
