The Zone Reclamation Project

Yes, it is possible to play the unmodded game and never encounter the permanent radiation bug or broken doors. You might never have a show-stopping crash to desktop (CTD) or take on a quest that cannot be finished. But the odds do not favor you; the more you stay in the Zone, the more likely these vanilla issues will occur even in the patched game.

Based on bardak's excellent Patch 1.0004 bug fix attempt, the ZRP bug-fix patch-mod is a community effort to fix bugs and address some annoyances found in the vanilla (unmodded) version of GSC Gameworld's game "S.T.A.L.K.E.R. - Shadow of Chernobyl" while retaining vanilla gameplay.

It also has a host of configurable items so that you can tailor your game experience to your liking. You can make the patch-mod even more vanilla by restoring some of the buggy or annoying vanilla behavior and disabling ZRP feature enhancements like the ability to continue playing after the game's story line ends.

Requirements: - "S.T.A.L.K.E.R. - Shadow of Chernobyl" installed and patched to 1.0004, 1.0005 or 1.0006. You do not need to start a new game, although some fixes and features will not be available unless you do.

Compatibility: Many simple mods can be easily merged with the ZRP. You can use any all.spawn that comes with the other mod, although you might lose some bug fixes and features. If you are using the Smart Mod Manager by Don Reba, you should give priority to the other mod(s) for version 1.05, and to ZRP for 1.07. The ZRP has worked with:

  • Graphics mods
  • Skin and texture mods
  • Sound mods like Darius6's Sound Overhaul, {imperialreign}'s Ambient Audio Overhaul
  • Most trader repair mods (with care in installation) -- but you can enable the built-in repair guys with a click
  • Weapons and ammo mods
  • Weather mods, like Stalker Skies, nandersen's Dynamic Weather and trojanuch's S.W.O.

Please note that the ZRP has a lot of optional mini-mods already included. See below.

The mod has English (1.05 also has Italian) localization, but it should work with other languages. There are a few "large" mods that have incorporated parts of the ZRP (e.g., DC- and gannebamm's aliVe 1.6), used earlier versions (Stoll's STALKER Mod Compilation uses 1.05 R10, artistpavel's STALKER Complete 2009 uses 1.05 R11) or are planning to use it in future releases. (You should encourage your modder to use bardak's bfa or the ZRP as a base for their mods.)

Can your mod do this? The ZRP has been crafted for fixes and flexibility. You can enable/disable features without having to start a new game.

  • It works with official patch versions 1.0004, 1.0005 and 1.0006 even if you upgrade.
  • It can use existing vanilla saves; no need to start a new game.
  • It can repair problems in most existing vanilla saves.
  • It can work around problems in all existing vanilla games.
  • It loads saves faster than vanilla.
  • It generally increases frame rates versus vanilla for comparable settings.
  • It permits you to start anywhere, anywhen in the story line.

Partial list of bugs fixed as of 1.07 R3:
  • Almost all fixable game "crash to desktop" exits are fixed.
