S.T.A.L.K.E.R. Anomaly is a mod pack based on Last Day 1.3 with many addons and custom tweaks. It's quite demanding on the system, but it's running on a 64 bit engine so it should be able to utilize more RAM than the original 32 bit engine.

The pack is built for and uses the DX10 renderer. Other render engines may or may not work, they are completely untested. The recommended way to play this pack is to leave all options unchanged. Only change options that are depending on your hardware and setup, like screen resolution and audio volume.

If you really want to change any game play related options, I recommend to do that before starting a new game and then never touching them again.


The 64 bit engine is also publicly available on BitBucket and might be able to run other mod packs based on Call of Chernobyl 1.4.22 but it has only been tested with this pack. During normal game play, it's normal for the game to use between 8 GB and 12 GB of memory.

Two versions of the 64 bit engine are included in this pack. If your CPU supports it, I recommend to use the normal executable (with AVX support), but if your CPU is older you may have to use the non-AVX version or the game will crash when you start it.


The 64 bit engine is still experimental, but it has proven to be quite stable during almost 100 hours of playing this pack. If you encounter any crashes, first try to load the latest save. If the crash happens again, post a bug report on the Bug Tracker and attach the save game and a short description how to trigger the crash. I'll look into it then and if I can reproduce the problem, there's a good chance I'll be able to fix it and update the engine with a bug fix.


Install instructions on the Anomaly Forum


To play, use either START-x64.bat to start the normal version or (if you have an older CPU) use START-x64-noavx.bat to start the non-AVX version. This mod pack requires a 64 bit version of Windows to run, it won't work on 32 bit versions of Windows.


If you are playing a Last Day based game for the first time, I recommend to select the faction 'Loner' and the starting point 'Rookie Village (Cordon)' in the character selection screen. Leave all 4 options turned off.

You may also want to change the player name in the top left corner of that dialog. It's preset with the name 'Last Day', but can be changed if you click on it.

The auto-save mod will save the game automatically every 5 minutes, but you can also use F5 for quick saving before you try anything potentially dangerous. It's also recommended to make a hard save from the pause menu every now and then, I usually do that every time after travelling to a new area.



The included mods and addons are mostly made by other people and most of them are available on MODDB. What I did is to assemble this mod pack and create a 64 bit version of the game engine to run it.

Apart from Last Day 1.3 with the latest patches and translations, this pack also includes parts of these addons:

  • Absolute Nature
  • Absolute Structures
  • Artefact Overhaul
  • Auto Save every x seconds (5 minutes interval)
  • Autumnal Winds

  • DRX Dynamic Faction Relation (since update 4)
  • Open Scopes (since update 4)
  • Disguise System (since update 5)

I have enjoyed playing the Stalker games and mods for many years now so I decided to download and play Stalker Anomaly yesterday as it has a good rep.

Unfortunately both I and a Reddit user have both discovered that the 1.3.1 to 1.4.0 repacks have missed including the system.ltx file so on loading we inmmediately get the 'd:\stalker anomaly\gamedata\configs\system.ltx missing' error message. It can't be found in any of the three repacks currently available.

Could anyone let me have a copy of this essential file?
