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".

I have encountered new type of anomally unknown to me.
Brief characteristic:
-invisible to detectors (they are unable to detect it)
-do not form any known type of artifact as of my knowledge
-what kind of damage it causes? None apart from the fact I almost **** myself when I found one
-ordinal look, undistinguishable from old truck wheel apart from the fact that old truck wheel doesnt do sound effect when angled:D
Dont take me serious, I am kidding. I like the game so much now I cannot stop playing it.

Well ok.. then send us a log and savegame, so we can replicate your crash. Why is it important to have a savegame file? It contains many useful info about the game version and/or mods you used. Also if you're playing the russian version (just guessed from your profile), that crash you had can be in relation with the localisation.

Make sure youre playing with the official version of Lost Alpha with the latest patch, these all can be downloaded from this site. We can not give support for modified content.

Maybe you didn't restart the game after applying max settings, so they were never used on first patch. New settings affect the game only after you restart the game.

Grass shadow (CPU/GPU), MSAA (GPU), SSAO (GPU) are the most demanding graphics options which should be disabled in most cases.

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…
