S.T.A.L.K.E.R. Trilogy guides and information
STALKER Quickstart
Before Installing
Which game should I play first?
The best way to play is the order they came out: SoC, CS, then CoP. There is no “best” game in the series, and everyone has their own favorite, so playing this way will introduce you to the mechanics and story in a natural way and let you decide for yourself which you like most.
Where should I get them?
GOG and Steam if you want to pay. GOG.com has the best copy. It’s as “clean” as they come and includes bonus content like wallpapers and concept art, if you’re into that sort of thing. Steam is also acceptable, but has a history of being poorly patched and forcing updates.
If you want to get it for free, download the repacks from drive.google.com/drive/folders/1mhwMy4wSQQ4PC9-YxEAZMX0Pf1ZbS2b0?usp=sharing
Should I mod my first playthrough?
Yes, but not much. The games are still perfectly playable on their own and every overhaul has its pluses and minuses, so only bugfixes and graphical updates are recommended for your first time. We’ll come back to this a little later.
Setting Up the Game
After installing any of the games, open up your install directory. Find fsgame.ltx and open it with Notepad or any other text editor. The first line ($app_data_root$) controls where your settings, saves, screenshots, and logs are stored. Replace the entire line with the following:
$app_data_root$ = true | false | $fs_root$ | appdata\
This will make sure your user data is saved in the game directory itself instead of somewhere in My Documents, and is recommended so you can easily locate it again as well as avoid conflicts if you install multiple copies of the same game.
Launch options
If you’re using Steam, you can access the launch options by right clicking the game in your library, going to Properties, and clicking the Set Launch Options button. For non-Steam copies, open the properties of your shortcut and add them to the end of the Target field, after the closing quotation mark. Please note that all of these are optional.
-ss_tga
Saves in-game screenshots as higher-quality .tga instead of .jpg-smap2048
,-smap4096
Increases shadow rendering quality-silent_error_mode
(SoC only) - Skips the useless BugTrap window if/when the game crashes-nointro
(SoC only) - Skips the beginning splash screens, but also the new game cutscene, so wait until after you’ve started your game to turn this on-noprefetch
(SoC only) - Skips preloading common assets like weapons in favor of only loading them on demand. May decrease loading times but increase occasional stuttering
Console settings
Boot up the game and press tilde (~) to open the console. There are a ton of advanced graphics settings in here if you care to explore them (enter “help” to see all commands), but here are a few recommended changes.
cam_inert 0.4
Reduces mouse smoothing and head bobbing, among other things. The default is 0.7, which almost everyone finds too much, but how low you want to go is up to you.r2_sun_near_border 1
Helps fix some shadow bugsr2_sun_near 30
Fixes weird shadow blocks around the corners of the screen. The higher you set this the less often you’ll see it, but the quality of nearby sun shadows will also suffer.cfg_save
Forces all settings to be saved. If the game crashes, any settings changed during that session will be reverted if you don’t do this, so I like to run it after getting things to my liking just in case.
Game options
In CoP, never use the DX11 render; it’s quite broken.
Always make sure the Antialiasing slider is completely off; in-game AA is horrible.
Read through the keybind list; you will need to know and make use of them.
Disabling the crosshairs is highly recommended for IMMERSHUNS and encouraging good habits.
Finally, if you’re having problems running DX10 in CS or CoP, try uninstalling MS Update KB2670838; it has been known to cause issues.
Modding Basics
Stalker assets come in two forms: packed up .db files and a loose gamedata folder. If a file is present in the gamedata folder, it will override the one(s) in the dbs. All of the vanilla files are in dbs, so as long as you don’t mess with those you can easily revert to vanilla by deleting the gamedata folder, which is what most mods are distributed as. Don’t be confused by the “mods” folder in SoC; it’s just used to store some unlockable multiplayer content, and very few mods make use of it.
Installing mods
Since the game doesn’t come with mods, there is no gamedata folder by default; all you have to do to install one is copy the mod’s gamedata folder into your game directory, alongside fsgame.ltx and the bin folder. Speaking of the bin folder, this is where the game engine is stored. If you ever install a mod that includes a modified bin folder, back the vanilla one up first. There is no easy way to revert it if you don’t.
Compatibility
Due to Stalker’s very basic mod loading system, any even slightly complicated mods are almost certainly incompatible with each other, or at best overwrite each others’ features. Mods which are focused on totally different things and have no files in common are usually fine together (such as a purely shaders mod, a purely textures mod, and a purely weapons mod), but you should always read the readmes for each mod to make sure you’re using the correct version of the game and have installed them correctly.
Crash Logs
At some point, due to improper mod installation or just bad luck, you’re probably going to CTD (Crash To Desktop.) If you expect anyone to help you, make sure you provide the following information:
The crash itself. After crashing, the cause will usually be automatically copied into your clipboard. You can also find it by opening the log file in your appdata folder and scrolling all the way to the bottom. If all the clipboard says is “stack trace:” you should check here for extra information. When in doubt, just upload the entire file to Pastebin or a similar service.
The game and version you’re playing.
What mods, if any, you have installed.
Please note that the BugTrap window is basically useless and you can safely ignore it.
Gameplay Tips
Master is the recommended difficulty; it puts NPCs on a more even footing with you.
Stalker is not a run-n-gun shooter. Finding good cover and aiming carefully is essential.
In SoC, artifacts that say +Health increase your health regen, not your total health.
The stat meters in weapon descriptions should only be used to compare weapons of the same caliber.
Scopes and grenade launchers do not affect stats, but suppressors incur steep penalties.
Recommended Mods
- ST Fov Editor
This utility will let you change the field of view, which can’t be done in-game. - xrPatch (scroll to the bottom to find it)
This utility will let you change how far away grass is rendered. Not for weak computers.
Shadow of Chernobyl
Essential
- Zone Reclamation Project
Fixes a slew of bugs, both major and minor. It’s worth being aware that it does have a small effect on gameplay, but not much. Get 1.07 R5 if you intend to use OWR (see below.) - Shaders MAX
Includes optimized shaders and some extremely dubious new graphical effects. Use the Full Performance preset to get the former without the latter.
Recommended
- Original Weapons Renewal 3
Overhauls weapon assets without changing balance at all, unlike the CoP version. Remember to grab the ZRP compatibility patch as well. - Photorealistic Zone 1
A small collection of high quality vanilla-style textures and bump maps.
Clear Sky
Essential
- Sky Reclamation Project
CS is by far the buggiest game in the series; SRP gives you a fighting chance at completing it. - Shaders MAX
Optimized shaders. The unpleasant graphics changes mentioned in the SoC section are off by default in this version, thankfully.
Recommended
- Absolute Nature
A nature texture and model replacement. Not quite as good as the CoP version, but still pretty decent.
Call of Pripyat
Essential
None! CoP is pretty well optimized and bug-free out of the box, so if you want to jump right in, go ahead.
Recommended
- Absolute Nature 3
An excellent nature texture and model replacement. Unfortunately the newer 4.01 has issues with some objects turning invisible, so stick with this for now.

If you’re looking for mods for your first playthrough, this is not the page for you. Please visit the Quickstart Guide instead for more on that topic and other important information for beginners.
Finding Mods
When looking for a particular mod, please always try to find the official source to ensure you have the latest version, necessary patches, etc. Here are some general sources for mod info and downloads.
ModDB
Most major Western mods and some of the more well-known Russian ones are hosted here, along with many guides, media, and addons for them.
AP Production
The best single source for Russian mods. All but the most obscure and ancient shitmods can be found here. In addition to the links below, there are also subforums for mini-mods, addons, and more.
/vg/ Repositories
An extensive collection of mods large and small. If you can’t find something elsewhere, check here.
Miscellaneous Western Sites
GSC Game WorldDEFUNCT, try the internet wayback machine
The official GSC forums; each game has a mod discussion and mod downloads section. Houses the official threads for some important mods like ZRP and SRP.- Nexus Mods
While historically pretty dubious for Stalker mods, Nexus mirrored FileFront’s entire catalog after they went down, so there’s a trash/treasure trove of old mods here (as well as a few newer ones.) - TKGP’s Mod Status Page
Along with some small mods and addons, this page has a ton of translations for many Russian mods.
Miscellaneous Russian Sites
- AMK Team
The old AMK forums are still alive and kicking, and they have a pretty decent selection of threads about new and old mods alike. - Stalkermod.ru
One of many Russian mod catalog sites, but more up-to-date and extensive than most. If you’re looking for some truly rare shitmods that aren’t on AP-pro, check here.

Frequently Asked Questions
How does difficulty actually work?
Please refer to this image, determined from the source code instead of guesswork and anecdotes.
What’s the deal with Complete?
The main deal with Complete is simply that it’s old. Its component mods are outdated and its assets aren’t up to modern standards, so the main selling points of the series are pretty much moot. In addition, CoP Complete actually adds common new crashes that aren’t present in the base game. Most controversially, SoC Complete radically changes the balance of the game across the board, increasing carry weight, reducing damage, dumbing down AI, and just generally making the game easier in ways that eliminate decision-making and strategy. We don’t recommend playing it for any reason.
Legacy Links
These links are, in my opinion, too outdated to be worth using any more, but have been retained for historical purposes and the off chance you can find something useful in them.

THE BASICS
Stalker starting guide: http://i.imgur.com/BHEfeh.jpg
What is STALKER what are the STALKER games?
Open ended Survival-shooters with minor RPG-elements.
No “Leveling up” or gathering EXP. All real time action and personal skill gain
Realistic gunplay with bullet physics, character bleeding, specialised ammo types, factions, mutants.
Set into an alternate version of the Chernobyl disaster Zone.
Which Stalker should I play first?/ In which order should I play the games?
In the order they came out, Shadow of Chernobyl, Clear Sky and Call of Pripyat
Arent these games unplayable without mods?
Not true at all, with the latest patches the three games can be played start to finish, the mods are meant to be an enhancement or a polishing, like Shaders max giving a good bump at the graphic while giving a better optimization or "Zone reclamation Project" which only fixes errors and bugs and nothing more.
MISSING FILES(?)
A huge Stalker repository, something I could not do with my awful connection, thank you Anon.
https://mega.co.nz/#F!zEtSxC4J!eRsovn-n098UpRtLDmr5_w
What does the S.T.A.L.K.E.R. STALKER acronym means?
Scavengers, Trespassers, Adventurers, Loners, Killers, Explorers, and Robbers
Can I run it?
Check here http://www.systemrequirementslab.co
Some mods (like Shadersmax) improve performances, you should also take care to fiddle with the many video features Stalker has, it even has non dynamic light.
Which is the best weapon?
Is hard to tell, speaking of SoC, pistols are weak and you will hardly find anyone using them, but you should not give up on them, they are light weight and as some casual game once said, is faster to change weapon rather than reload, while in AMK some latter ones will put down even the stronger mutant or human, the AS VAL by the statistics should be the best and is actually very good, but more than one Stalker found little problems finishing with just an AK variant or the SIG and the right ammo.
How do I repair my Weapon/Suit in Stalker SoC?
While Complete 2009 has repair kits and services and AMK too, Vanilla SoC does not, but there is still a way.
You need to have enough artefacts to have more than 100% protection against an anomaly in particular, a popular choice is finding enough of the artefact "battery" for the electro anomaly, in which you have to get in, note that Artifact and Suit protection do not stack.
I wish be able to loot STASHES (in any Stalker) without the need to gather the information beforehand
For Stalker SoC: (needs a new game) Vanilla: Stalker.filefront.com/file/Stashed_Mod;82898
AMK: http://www.mediafire.com/download/2gmr5mau9p3cp2r/stashed_for_AMK_EN.7z UPDATED LINK NOW WORKING
ZoA: Broken link.
For Stalker CS: (no need for a new game) http://www.moddb.com/mods/ymmcs/downloads/stash-filler
Where do I buy 9x39 ammo? (for the AS VAL for instance)
At the Duty base/Bar there is a second trader, a Duty Colonel who sells them, the Barman seems like he never does, so through the entrance of the bar, then take a right. go along a corridor until you find a colonel. talk to him.
STEALTH
You might find better opinions regarding Stealth in Stalker but for now hear my words, Stalker has a degree of stealth, so is not completely impossible, it just looks like it due to how it works.
Enemies can hear and see you as much as you supposedly should, what tends to trick player is how they take many things for granted.
Again, if you can see them they can most likely see you if they are not looking the other side and nearly everything you do makes a sound, not just walking or shooting without a silencer, even equipping something.
You might get the impression also, that reloading a quicksave breaks the stealth, it does, it seems to reload the AI, apart from whatever machination might go through the XRAY ENGINE, everytime you reload the game you re-equip whatever thing you had, thus making noise and alerting the enemy.
I finished the game, now what?
Played SoC? Play CS, then CoP.
Use Mods, refer to that section of the Guide, roam the zone, some mods like AMK let you play after having finished the game and thanks to his A-Life there will often be something to do, other mods are like whole new games, such as Lost Alpha, or Soup.
Or else do the Stalker challenges http://i.imgur.com/UENJn.jpg
BETTER GRAPHICS GRAFICS
Refer to the Stalker starting guide, with the Absolute texture packs but what isnt mentioned (and should really be damn it) is this Texture pack, which is what is included in Complete 2009
http://kocayine.ru/photorealistic/
Creatures and Stalkers, althought, NOTE: Does the first one clash against "absolute structures"? A question that need to be answered ASAP.
Enabling AA AntiAliasing, AKA "how to remove jaggies from edges"
AA slider in Stalker SoC does not work, put it all down and use instead
http://mrhaandi.blogspot.it/p/injectsmaa.html
Read the Readme. or simply put, put the files in "d3d9" in the "...\stalker shadow of chernobyl\bin" folder where the EXE is, if the game crashes then put the DLL file in the \bin directory and the other files in the previous main directory.
Start the game as Admin, when in game, get in the menu press the "PAUSE" key on your keyboard, but it might be activated already, use STAMP for screenshots, the difference is very noticeable.
Comparison screenshot http://i.imgur.com/xAoePh.jpg
Sorry that I cant tell what the Framerate difference will be, my framerate is good but too unstable either way. You will have to see for yourself using "rs_stats on" command or FRAPS.
AA enabled from the Nvidia GPU control panel works too, I have tried CSAA, later I will make another comparison screenshot, FXAA might work too and use less resources.
I should probably make a screenshot with Trees/vegetation later.

http://enbdev.com/download_mod_stalker.htm
Installation instructions (by Vynil Scratch):
enbbloom.fx, enbeffect.fx, enbeffectprepass.fx, enbpalette.bmp, enbseries.ini, injector.ini, SMAA.fx and SMAA.h all go in common/stalker soc folder, d3d9.dll and d3d9.smaa.dll go in the bin folder then delete the shader folders from gamedata.
BUGS, HELP, CRASH, FREEZE, ERRORS Troubleshooting
Check your Documents/STALKER-SHOC/logs folder for the SOC crash log, other STALKER games use similar STALKER-folders under Documents. Steam users: the game uses the $app_data_root$ path on first line of fsgame.ltx in your STALKER install folder.
Find the last few lines of the text file, and copy-paste those in the thread if you want any assistance. A list of common crashes and bugs can be found here:
http://www.metacognix.com/stlkrsoc/CrashesStillInTheGame.html
As soon as the game crashes, open the bloc notes and Ctrl+V to paste the crash log.
Zone Reclamation project is a good idea to start well ahead of the bug race even if the game can completed, mostly without an hitch with the vanilla game and its patches http://www.metacognix.com/files/stlkrsoc/index.html
GAMESPY CRASH
A very recent crash has arisen, caused by Gamespy servers, because SoC uses those servers for online play, the crash log reads
"Loading DLL: xrGameSpy.dll
! Unable to init Server Browser!
stack trace:"
SOLUTION:
- Turn off internet
- There's a solution in this Steam support thread apparently http://forums.steampowered.com/forums/showthread.php?t=1413521
Can't find texture
'ui\ui_nvidia_intro'
Start the game with the command -nointro
Reminder: MS Update KB2670838 breaks your DX10/11 games including Clear Sky and Call of Pripyat. You can safely uninstall it.
(thanks anon)
Some of my shots seem to not hit the target no matter what
- Stand still, aim down the sights, possibly crouch and use the single fire mode.
- Alas the starter pistol aim is awful and his stopping power scarce, so that might be a turn off for some, personally what I do is either get up close and aim for the head with the chance of getting my hands on a Sawn off shotgun or use the Knife, always the secondary fire thought, while slow it can be a one hit kill even for the heaviest target.
- If you still have troubles with this, is not your fault, the game has a dice roll function where some shots at a certain distance simply wont exist anymore, to solve this:
In weapons.ltx
under [bullet_manager]
change hit_probability_max_dist
from 10 to something like 1000001
This increases the distance at which dice rolls takes effect to one that exceeds the distance for any sort of engagement in the game, thus eliminating it.
Also, you shouldn't forget to modify the k_dist of each bullet type, and the fire_distance of each weapon to their real world equivalents.
Once this is done, none of the bullets will disappear mid-flight.” FatalFunnel (note: ZoA has this function removed already)

Shadows are broken
A common bug with widescreen monitors, where the shadows of the terrain get “sucked” into the borders of your screen. Open your Console (~ ) while in game and type these two lines
r2_sun_near 20
r2_sun_near_border 1
KRUGLOV get killed by an Anomaly
More likely to happen in AMK, because of the random anomalies one might get into his path and kill him, so either:
Sleep to reset them, try "activating" it/them Or, this works for VANILLA too, move far away, it should be 150 Meters, so that A-Life kicks in and he goes automatically.

How do I change height and crouching in SoC? Also how to enable Prone
In vanilla SoC / ZRP the player's eye-level is too low compared to other humans by default. You can edit this with ZRP's modifier, using Actor.cfg to install actor.ltx, choose Camera Viewpoint entry and raise it from default 0.85 to 0.94.
Most overhaul mods do fix the player's height by default.
find/extract/unpack config\creatures\actor.ltx
, edit it in text editor. Eye Height is set by camera_height_factor
, height is Y component of X,Y,Z values for ph_box#_size
and ph_box#_center
.
The # value is 0, 1, and 2, for standing, crouching and low crouching.
Going Prone
Edit your actor.ltx
file with these values:
ph_box0_center = 0.0, 0.9, 0.0
ph_box0_size = 0.35, 0.9, 0.35
ph_box1_center = 0.0, 0.65, 0.0
ph_box1_size = 0.35, 0.65, 0.35
ph_box2_center = 0.0, 0.2, 0.0
ph_box2_size = 0.35, 0.2, 0.35
This will make it so low crouch will now make you go prone

Loading times are too long, what to do?
Add in the game destination (so go to your Stalker SoC icon in the Desktop or the start up options for those who use Steam) and add the line
-noprefetch
so the game destination will probably look like this.
“C:\Program Files\THQ\S.T.A.L.K.E.R. - Shadow of Chernobyl\bin\XR_3DA.exe" -noprefetch
What does it do? “it will disable the prefetching which occurs when STALKER loads up a saved game, preventing the game engine from preloading a range of resources into memory. “-Tweakguides
and somehow help prevent stutterings too.
Add in-game playable Guitar and Harmonica (you can purchase it from Stalkers or traders)

This means when you drag a body, if you walk backwards you can drag it at running speed!!!!.... just don't run your arse into a sprinboard.
I can hear an echo in the Wind that follows me
That is likely to be the "controller", it wont happen in Vanilla
I can still hear after having killed the Controller his chant
A bug that occurs very often, either save and load, change map, or quit the game.
Dialogue modifications
the dialogues are confined within
config\text\rus
(or eng
)
Remove the ironsights zoom
Extract config\weapons\
(gamedata.dbb
should have it) to a folder. Edit all the w_*.ltx
files andset scope_zoom_factor = 60
for no zoom.
Don't change it for the scopes in weapons.ltx
.
BLOWOUTS/Emissions
Gameplay wise all you need to know is the horn will play and you need to find a safe place until the Sky isnt bleeding anymore.
Blowout frequency
the relevant file is gamedata\config\blowout.ltx
and it should look like
[blowout_period]
enabled = X time = Y shift = Z
Enabled is on (1) off (0)
"Time" is the mean time period measured in (in-game) minutes, for example you want a blowout four times per week then set it to 2520.0
"Shift" is the uncertainty about the average period between blowouts. Using in-game minutes, so if you want the period to be a day then it should be 1440, or 720 for half a day

STARTER PACKS for the best vanilla experience, download links and installation instructions
https://www.youtube.com/watch?v=XHWKexK7B_8
http://www.gsc-game.com/index.php?t=community&s=forums&s_game_type=xr&thm_page=1&thm_id=21075&sec_id=16
Check moddb.com and Stalker.filefront
Where are they installed and how do I remove them?
The first time you will have to edit your fsgame.ltx
in the install directory, open the file with a text editor like Notepad and find the following line
$game_data$ = false| true| $fs_root$| gamedata\
and change the false
to true
Some mods come with an EXE, others will have to be dropped in the main Stalker folder, they always come in a folder called gamedata
which you drop along the other main folders, so to remove a mod simply remove that folder, without the need to download everything again.
I WANT MORE GUNS
Each mod may usually add his own guns, AMK add back some deleted content among with a few guns, LURK mod have their own, Soup adds a TON of content.
But if you want just guns then use the Arsenal mod
(Note to self, must add more links)
STALKER WEATHER OVERHAUL
Graphic mod for the Weather.
Look into the repository
AMK guide
http://i.imgur.com/huLmZ.jpg
download that includes retranslation and patches http://www.mediafire.com/?8wm243dsc0dlwm7
AMK and artefacts/artifact
AMK adds new artefacts, which you can randomly find in stashes thanks to his peculiar system, around the Zone (blowouts adds them) and there's also "artifact cooking", where you will be placing them inside certain anomalies and wait for the result, different persons will give out the receipt for them, but here's a handy guide http://i.imgur.com/dOHHnh.jpg
MORE GUNS FOR AMK/Arsenal for AMK arsenal
So you want more guns? Ok but you cant just add Arsenal to AMK, head here for all the files
Download the AMK Arsenal Mod V1 and install the gamedata folder. Also install the gamedata
folder in “Randomized Weapons for AMK.” Install any other extras you want but do not install “controller zombification!”
B. Download and the install AMK Arsenal V2 Patch.
C. Download the AMK Arsenal V3.1 Patch and install both gamedata folders-SomethingforNobody SoC Guide

http://www.mediafire.com/?c8w9blhd8xgmv6a
http://www.mediafire.com/?fn0nj58pg79dnln
It should even make the game harder because this mod includes
http://stalker.filefront.com/file/PLRs_Realistic_Weapons;88736
NOTE: Likely to have a bug where enemies start using solely pistols, to fix this read here
QUICK FIX:
What happens is the "fort-12" is accidentally tagged as a sniper rifle in arsenal, go to the gamedata/config/weapons
folder and find w_fort
and change ef_weapon_type
from 3 to 5.

You could add Arsenal 1.2 to AMK but, is hard.

use it to change between strong/weaker monster and visible/invisible anomalies.
"Can I mix AMK and ZRP? (Zone reclamation Project)
Nope.
The AMK Mod guide that was on a Google Doc
see pic
Also see FAQ. FAQ has fix for NPCs preferring pistols over rifles; some pistols have ef_weapon_type of 3 - should be 5.
Consider ZoA (Zone of Alienation), too.
Done with vanilla/ZRP ? Want some extra challenge and features?
Then try out the "defining" Stalker mod, AMK1.4:
http://www.mediafire.com/?8wm243dsc0dlwm7
If you're playing on Steam / GOG / 1.0005 or 1.0006 patch, you NEED to downgrade to 1.0004
First run Amk 1.4 setup, then AMK EN patch final.
Install AMK Retranslated last.
You can use same graphical mods found in STARTER PACK with AMK. In case of SWO2.2, remember to apply its own AMK-patch last, or your game will crash!
[#FDL] = Full Dynamic Lighting, [#SL] = Static Lighting.
ZoA: You need SoC 1.0004 + mod + patch 13 + hotfix for Dark Valley Dynamite_immunities_sect crash
http://www.moddb.com/mods/zone-of-alienation-mod/
FAQ by TKGP: http://pastebin.com/pKBibDLS
Until the 1.0006-compatible update, don't use "take all" with rucksacks. It breaks the magazine function.
ZRP controller kill function for AMK/ZoA
Controller dBodyStateValide(b) crash fix
Looks okay for AMK and AMK-related if they don't change the file otherwise.
Not recommended for vanilla! AMK changes a lot of other stuffs in that file."
AMK derivatives
Just like AMK these mods will work better under the 04 version of the game, AMK itself has a compatibility patch which can be used to play on the Steam version of SoC (version 05)
But since ZoA and other AMK derivates do not have such thing you will have to either patch the game to the 04 version or DOWNGRADE it if you have the Steam version, here is how:
http://i.imgur.com/zZs7pep.png
Stalker ZoA (Zone of Alienation)
"ZoA isn't meant to be enjoyed, if you're having fun, you're doing it wrong."-FatalFunnel 2012
What is it
“An adaptation of the renowned AMK mod. It is built on top of a specialized variant of AMK that uses a magazine system”. Created by moddb user and trip FatalFunnel
Where can I find it, and what does it add?
On the premises of AMK is also much more difficulty, with more weapons, improved AI, more quests, better graphic, optional freeplay and an artefact detection system with old artifacts having altered properties.
http://www.moddb.com/mods/zone-of-alienation-mod/downloads
well somebody has made a pastebin about ZoA so instead of copy pasting that I'll put a link of it here.
http://pastebin.com/pKBibDLS
HOW DO I RELOAD? (in ZoA)
I want to remove the magazine/reloading system
You will have to mod each weapon's ammo_class to use the ammo types instead of the magazine types which are stand-ins.
You will also have to change the magazine capacity from 1 to whatever that magazine's capacity is.
I want to disable the depth of field/blur in Zone of Alienation.
go into gamedate/shaders/r2
and open Shader_settings.txt
put //
before #define
on the enable ddof or whatever values.
I want to disable Bloom and how does it work
- Turn off sun shadows, or you could just fiddle around with the ls_bloom_threshold in user.ltx.
2)
r2_ls_bloom_fast off
or,
r2_ls_bloom_threshold 0.3
- the higher the threshold, the less bloom you get.
More info on BLOOM settings
Also from FatalFunnel words "the most important one beingr2_ls_bloom_threshold
, which ranges from0.000
to1.000
, the higher values having less bloom, but you should also play withr2_ls_bloom_kernel_scale
, andr2_ls_bloom_speed
. You could also mess around with some of the shader settings." Thank you FF.

Secret Trails 2
I have found myself playing this nice Russian mod for SoC, new locations, new story needs the version 04 and that you add the command line "-nointro" to the game shortcut destination.

NOTE: IF YOU DONT PLAY WITH THE 1.0004 VERSION THE GAME WILL NOT WORK AT A CERTAIN POINT.
If you are playing on Steam AND OR with the 1.0005 version then follow this guide to downgrade it
http://i.imgur.com/7BLfJh.jpg
FOLLOW IT, delete those gamedata files, DO IT OR THE MOD WONT WORK, IF YOU COME WHINING THAT THE GAME CRASHED AND YOU DID NOT DO THIS I WILL PUT A DROPLET ARTEFACT WHERE THE SUN DOES NOT SHINE.
In a nutshell, you came to play Paintball, you lost your brother and woke up some years later, you will now be searching for him, the game is "linear", the maps are Stalker like but they wont let you wander around....at least at the beginning, I think with this new content and missions is more than worth the play.

Not much info from me, but I wish to introduce this mod as it has quite some interesting original features which should be explored, expecially by other modders.
Doom's mod merge
Download: https://mega.co.nz/#F!zEtSxC4J!eRsovn-n098UpRtLDmr5_w
what is it?
"Facepunchfs own Sgt. Doom has developed this small mod merge combining the Freeplay mod and an unknown weapon pack. You can spawn as almost any faction member and do missions for the faction accordingly.
The so-called "unknown weapon pack" is actually the weapons from LURK 1.1 ported over. This mod is about as closed to total freeplay (because it IS totally freeplay) as SoC will ever get."
This is anon's modification of it.
COMPLETE 2009
I leave you to some "old" but trusty copypasta about it
"For better or worse, here is 'Why Complete 2009/2012 Sucks!' (except for Clear Sky)
- All weapons have their accuracy increased by 10-20.
- Damage done to everybody is decreased by various percentages.
- Weight limit is increased by 10kg, the maximum being 70kg. In vanilla, the Exo-suit enabled up to 80kg!
- Limits NPC's eye sight distance so they can't spot you from beyond ~100 meters. Said to remove enemies skill to spot you from "unrealistic distances," but really means you always see them first every time.
- Sound radius of the knife and other critical sounds such as death cries, falling dead bodies, night-vision goggles, grass, and footsteps are greatly reduced.
- scientific suits with 90% rad protection now feature an anti-rad injection system.
- Bandages auto-apply at 10% health.
- An older beta version of ZRP is used for their "bug fixes," making it less stable than vanilla with the latest version of ZRP.
The following features are also available in other mods, but are usually balanced out with other forms of difficulty: - You can bribe hostile factions to leave you alone.
- A repair kit that lets you service your armor and weapons without the need for a trader can be bought from traders.
- The bar trader and Screw now sell weapons and armor repair services.
- Elite Nightvision, essentially the black & white night vision based on the psy_antenna postprocess effect, replaces the original UV-based blue NV. Perfect vision in the dark is now possible, even without a real light source."
So there you have it.
Stalker CoP
many things said for other Stalkers apply to this one as well but I should update, enrich this part and play this game already.
Here something I quickly put for those who are playing the CoP mod
MISERY
I dont know who made this, is a bit of general knowledge for many Stalker who since the release of the mod had problems with Stamina and other things as well in Misery.

Why weapons are mirrored / ejections ports are in the wrong side
Official explanation
http://www.gsc-game.com/index.php?t=community&s=forums&s_game_type=xr&thm_page=4&thm_id=100&sec_id=0&page=1
"This issue was raised many times. However, I'll repeat our standpoint once again.
We are perfectly aware of what side the breechblock, ejection port and stuff is. All other developers that make shooter-games with mirrored weapons know this as well.
This mirror effect is done deliberately to introduce additional dynamics and the feel of firing (in other words realism no matter how absurd it may sound) into the game. There are not so many people who'd be amuzed with watching absolutely static and lacking dynamics guns.
On the other hand, majority of the players (that's a fact!) has very vague idea about the layout of real weapons. Thus, they could not care less where comes what in the gun."
LOST ALPHA
OFFICIAL FAQ: http://www.moddb.com/mods/lost-alpha/features/lost-alpha-faq
IS STANDALONE AND FREE
INSTALL THE PATCH: http://www.moddb.com/mods/lost-alpha/downloads/stalker-lost-alpha-v130013-patch
- INSTALL ALL THE 3D PARTY APPLICATIONS inside folder "3rdparties"
- Force Vsynch from your GPU control panel. because 1) As with Starcraft 2 (google it) the menu has uncapped FPS, leading to a potential GPU overheat 2) plus the devs themselves recommended it to fix another bug.
- If you are using a 32 bit system: "Anyone who uses 32bit operating system should remove the msvcp120.dll, msvcp120d.dll and msvcr120.dll from the game's bins directory. That will solve many problems. Also before game start, you can delete the user.ltx too and let the game create a new one based on your system specs"-Dezodor
- Changing the FOV
open the console with "\" then type "FOV XX" where XX is the number, usually PC games use 90, but Stalker's FOV is different so you might want to put something lower. - Disliking those pesky build 1935 gun models? TKGP got you covered, with most models being replaced from LURK and LWO
https://mega.co.nz/#!J5BzwQab!IXPxZD5dbPGYmdcIB4zIfGk2iaYa9x1y9bCg-24wbLw - Remove the black deathscreen in Lost Alpha, open the command console and write "g_first_person_death off"
- "optimal" user.ltx with bloom toned down, and actor's legs removed (they cause bugs) taken from Fatal Funnel.
http://pastebin.com/DNWv0CJB Goes in \S.T.A.L.K.E.R. - Lost Alpha\appdata - Dont bind anything to F5 and dont bind anything to a key already being used.
- Borov safe crash fix http://www.mediafire.com/download/9n85q5b82x53835/ui_safe.zip
- Drop suit from Agroprom underground before talking to Petrenko to avoid crash. Lower resolution if that doesn't work.
- Enter "r3_use_dx10_1 on" into the console for fps gain

Performance Guides, Steam settings
Before you ask anything: READ THE FAQ!
The famous TweakGuides guide to STALKER SoC: http://www.tweakguides.com/STALKER_1.html
Advanced tweaking starts here: http://www.tweakguides.com/STALKER_7.html
The -noprefetch command line tweak is on page 10.
Guide for Clear Sky: http://www.tweakguides.com/ClearSky_1.html
measuring FPS
You can see fps-counter and other stats by typing this to console:
rs_stats 1
Performance tips:
The in-game AA slider DOES NOT WORK in SoC. You can force AA on through your GPU's control panel. Avoid anything above 2x for minimal performance hit! Also AA might put a two-line border around your screen.
In CS and CoP, if you use ENHANCED FULL DYNAMIC -mode, set its three specific settings (SSAO, Sun Quality, Sun-shafts) to LOW. You won't notice quality difference, but your performance will skyrocket!
Another easy way to improve visuals and reduce random stuttering is to lower Vision- and Lighting distance, plus Object-Quality bar to around 50%. Again quality difference is minimal, but fps improves.
Reducing the Grass Density a point or two also may help stuttering outdoors. Some stuttering is just the game switching stuff online.
Steam players: Disable compatibility mode on the Steam launcher and on the STALKER game. Check to see if your antivirus is being a little too helpful. Turn off Xfire. More info at Steam STALKER sub-forum.
Sometimes Steam has two user file locations, but it uses the one shown on the first line in fsgame.ltx in your STALKER install folder. That tells the game where to find user files like user.ltx, saves and log files.
Reminder: MS Update KB2670838 breaks your DX10/11 games including Clear Sky and Call of Pripyat. You can safely uninstall it.
