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.

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".

Hello guys i have a question, i have a question.

Why is it that lost alpha doesn't run at full gpu clockspeed. When i play lost alpha it runs at about 750mhz, but when i play another game like skyrim with lots of mods it runs at the intended 1228mhz. I've tried to run LA with and without overclocks and the game keeps using only 750mhz. Could someone explain how this happens since the framerate is tanking a lot.

My gpu is an msi twinfrozr gtx770

Another observation i would like to make. In my case i noticed in that in the options menu when you choose the sound device i can only choose "direct sound". I have a creative xfi extreme gamer sound card. The reason i say this is because after the first pach i could choose my sound card.After the second and now after the third I can not do that anymore, only "direct sound"
A question for the team is about the S3r1ous mod pack. It is ok to use it?

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…
