Have you ever dreamt about playing the old, forgotten S.T.A.L.K.E.R. ?

We were amazed by GSC's work when they released the first S.T.A.L.K.E.R. screenshots in 2002. The old design, and atmosphere was stunning and we couldn't believe our eyes. Later in 2005 things has changed. They redesigned almost all old levels. Some of them became smaller, simpler (still nice, but different), and some levels were removed. After the release in 2007 we played the game a lot, and quickly noticed that some areas are missing. We opened forums, and talked countless nights about those for almost a year. Nowdays we could say, we have a full vision about GSC's old levels, due to the collected materials, videos and forgotten screenshots. We decided to remake those stunning areas, maybe they won't be the same, but we will try everything to make them look really nice, as we always wanted to see them. In early 2009, GSC released a build from 2004, which contained many old materials. We used some of the sdk objects for the level remakes, but adjusted (and bugfixed) them for our liking, also we didn't throw out our own levels. So expect to see our own Darkscape, Dead City, Rostok Factory and some more in Lost Alpha :)

Also need to say, Lost Alpha addon is not just about levels and levels. We will try to make a somewhat, but not fully restricted alife, and deliver a lot of new, never seen features, among with some old ones, which many people wanted to see for long. If you are interested in, check the Features menu for FAQ, Interview, Features List, and many more. Also do not forget to check the gallery, and the movies. All comments are welcome, also we are glad to see suggestions too, however at this stage those won't be considered.
Thanks for your understanding!

Finally, we would like to thank to the old Stalker Team this wonderful game. Without them, S.T.A.L.K.E.R. wouldn't be a "dream-game". Big respect to: Glory, Karma, Lex, Prof, Rainbow, Frodo, Dach, Koan, Mike, Jip, Jim, Jon, Yuriy, Terazoid, Tuz, Haron, Stohe, alexmx, chugai, Oles, Zmey, Iov, Sidorovich, CyLLlKA, dandy, Descruo, dima, Olga, LeSTAT, MadMax, Man0waR, Chapaev, Cy27-dw, Shyshkin, Narrator, Rolik, Atem, Yava, and many many more :)

Hey, hey hey! We are here, as we promised a month ago. It was a long road up until now, but there is finally a sun shining over us brightly. After almost three years, we can finally present you Lost Alpha Developer's Cut. We decided to release it as a patch for now, but after some hotfixes, we will create a full release of Lost Alpha containing all patches and DC as well! The files will be uploaded soon, and they will need to be authorized by ModDB crew, so be patient, and in the end... Have Fun!
Here is a little tutorial: After you download the DC patch, which is quite big (around 2.3gb packed) you need to unpack the zip file (with winrar or any archiving tool) to a clean directory, or to your desktop. But before you would do anything with those files, don't forget, that you need to have Lost Alpha patched up to the 3rd public patch (1.3003) first! If you don't have that installed, DC won't work at all. So if you have LA installed and patched up till 1.3003, run the DC patch installer and wait until it finishes. You can now run the game with the well known icon on your desktop. You will quickly notice the version number in bottom left corner, saying: "Lost Alpha ver. 1.4000 Developer's Cut". If you see that, then you are ready to play the game. Have fun, and if you have questions or something to report, send email to or post here on the chat window, and be patient, someone will surely respond.EMPTY LINE
Here is the final changes log of LA DC 1.4000: click here to open it!

Can somebody help.
I did not immediately help the guy, next to Sid's bunker (The guy who saved my life)to complete his quests as I first wanted to do some of Sid's quests. Now I can't find him anywhere. This means I can't get the USB and therefore I am not able to increase some of my skills. What do I do now??? Is there a way of solving this?

Am I the only one having trouble with the brightness on dx10? Everything is too dark... it's 3pm but looks like 3am. I already deleted the shader cache and the user.ltx and just set the main grafic detail option to maximum... it's still pitch black outside just because of rainy weather... i can also barely see in sids bunker. Anyone got a clue?

Try this:
r2_sun_lumscale_amb 0.75 (higher value = less dark shadows)
r2_sun_lumscale_hemi 0.95 (makes game brighter)

r2_tonemap_adaptation 6 (faster transitions for glowing/blinding effect)
r2_tonemap_lowlum 0.99 (almost removes glowing sky)
r2_tonemap_middlegray 0.9 (makes game brighter)

Middlegray is connected to HDR Coefficient slider in the graphics menu and r2_sun_lumscale is removed, so getting a lighter game without a glowing sky is a bit tricky.

PS: I've only tested these with limited weather conditions, might need adjustment.

I hope this has not been asked yet, I checked the last 20 or so pages and nothing on the topic...

I tried installing the latest internal patch from FB today, updating from the dodgy 1.4001 from earlier. (which I was using with the 2database files put back in the folder, without any crashes or problems)

I then decided to delete the User.ltx and shader cache as I was getting the same issue as others with actor legs, that is, no footstep sounds. Upon starting my old save with the new user.ltx I was getting truly nasty bright lighting on DX10 and 11, and couldn't find out how to fix it. (flashlight was blinding bright, underground corridors were like it was daytime) Tried reverting back to the old version and no change. I ended up finding my old user.ltx in the recycle bin, put it back and the problem is gone, although I had my legs back.

Ended up just changing the g_actor_body off and problems are gone.

Still, anyone able to shed some light on the issue? (Haha)

Why new version Lost Alpha is have not Russian localization? Lost Alpha 2014 is translated and voiced Russian team. Why did not you include this russian localization in the new version?

Hi DEZ. I am writing to you on behalf of the Ukrainian fans of the series stalker. You added to the official release Ukrainian localization S.T.A.L.K.E.R. - Lost Alpha (Developer's Cut). I'll text localization can offer in any convenient way. I hope in the future upgrade will be present Ukrainian text localization.

Will a full release of Lost Alpha have Russian localization? And in general, when a full release of Lost Alpha?

It's Lost Alpha. Should it be rated any less?

Full Review Here - This mod is a great example of what not to do when trying to recreate a game in your own image, due to it being worse than the SoC in almost every way. +Fantastic Map Design +Good Environments +Great Lighting +Textures better than vanilla +Upgrading System =Gunplay unchanged from Vanilla =Weapon textures + Models unchanged from Vanilla -Maps lack things to do in them -Sounds are subpar -Voice acting is bad and immersion breaking -Constant poorly animated…
