Got a LOST ALPHA Game problem?
Don't post it here or anywhere else on Facebook. Why? The ModDB and FB formats make posts descend to the bottom with each new one and your concerns can easily be lost. Too many pages and posts can make your problems disappear.
Where to go?
The GSC Forums LOST ALPHA section is designed to post Game problems and to provide answers. In addition the format makes it easy to find previous problems posted where you may not have to ask.

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 :)

Merry Christmas and Happy New Year
from Dezowave

Christmas is knocking on our doors again, chestnuts roasting on open fires and Jack Frost nipping at our nose. Another year has passed by, which brought us many good things and some not so good. At this time of the year we all should celebrate and concentrate on all the good that happened to us in 2014! First of all, thanks to your votes, we are in the TOP100 again on MOTY Awards, there are still 3 days left, and then the finals will begin. We are pretty excited about the results, even though we weren't really advertising it, but a little news post can't hurt. We were the first for at least 4 months in a row, and in the top 5 for almost 6 months this year from April till September, which was amazing. We are really glad for the given support from you and the Moddb Staff! The launch wasn't smooth, Lost Alpha killed the moddb servers due to the heavy visits and downloads, and we even beat Black Mesa in downloads and view counts when Moddb Staff compared the statistics of the 'day of release' of these projects. It was unexpected, and we felt honored. Later things calmed down, and we think we are on a good path now to finish the game. Those who regularly visit our site already know of the changes through patches, etc... so if they -you- think we have earned it, to be in the top 5 again, we will be there! Everything depends on your choice.

And a little status update of the upcoming developers cut. Our programmers updated the audio/sound engine of the game, now you can select all your sound cards from the list, and eax finally works, mainly on sound blaster cards, even the integrated sound chipsets which supports eax 2.0 will benefit from the changes. They also started remaking the weapon upgrade system, this time based more on the system in Call of Pripyat. The game designers are filling the empty parts of the levels with more "life" as well. Currently, we are testing the 2nd edited level of the 10 we plan to change. It's a long sequence, since we need to test run the levels individually, and in story mode as well, to see how the triggers work. When these are finished, we will check the keypoints in the storyline, and try to make the duller parts a bit better without destroying the "jenga tower" :).

Christmas and New Years is coming, with greetings of peace and prosperity, the whole dezowave group wishes the very best for you during this special time. May You enjoy all the best now and throughout the coming year. 2015 will be a cool year, it's not a secret we are working on our next project as well, which will be announced in a few months!

I don't think you can use that one but I'm not sure. My save is just before I enter the x18 lab and some previous comments told me to buy the download module before I enter the x18 lab so I have them both right now.

Also a suggestion to the admins, update it with a very detailed installation tutorial, there are lots of comments on youtube and your forums that call you guys lazy because you didnt include a very useful install guide.

learn to spell pal. By the way, this is all actually true, it took one guy 3-4 hours to find to dig information out on how to install it. There is so much in the files and lots of extras that hardly anyone knows what to do with. Ignorance of some folk.

Once you start extracting part 1 when it's about 25% done extracting it will move onto part 2 automatically so you don't need to do anything with them.
Just extract part 1 and once it's finished open the .exe file.
You can extract it anywhere since you'll delete the contents afterwards anyway.

It's not stopping and freezing it just takes a long time. the installation bar will be 95% complete but after that it will take about 10 more mins to get that last 5% install since it's 6 GB it has to do.
Just wait.

It took me about 5 mins too but since he claims it freezes I'm assuming it took him way longer.

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…
