STALKER: Lost Alpha on Steam (ENG)


Many fans of Stalker followed the development of this mod/addon from early on.

As a result, the release of this great game, and the owners of the steam version of Stalker SoC wondered if they could play it on Steam.

Lost Alpha is an INDEPENDENT GAME therefore just throw it in the folder with the original game will not work.

Now I'll tell you how to proceed.


1) Download the original version of the game via Steam (i.e just take and install Shadow of Chernobyl in Steam).

2) Download Lost Alpha.

You can download it from the official site or Moddb.

Official site is []

3) Then locate the folder where you have stalker, for example

Mine is in D:\Steam\SteamApps\common\STALKER Shadow of Chernobyl

And just delete the entire contents of the STALKER Shadow of Chernobyl (Delete everything in it), the folder itself called STALKER Shadow of Chernobyl, we save!

4) Run the installation of Lost Alpha

During the installation, the path we specify is this:

D:\Steam\SteamApps\common\STALKER Shadow of Chernobyl

A message that the folder already exists will come up, just click yes.

5) After installing the game, go to D: \ Steam \ SteamApps \ common \ STALKER Shadow of Chernobyl, there will be a folder namned bins , Rename it to bin

6) Now go to the library in Steam, and as usual run STALKER Shadow of Chernobyl.

That's all!

Tried as best as i could to translate it, But it was a couple of wierd things :P


Update: I just ran into the issue others have brought up that the overlay won't work with the patched versions.

Fix: For me the fix was to run the steam exe as administrator (windows 8 64 bit), after shutting down and restarting steam the overlay worked. I went back and forth a couple times to be sure, and it worked.

Thanks for the info Bearicus


All the credits goes to the user Six Of Laser who created the russian one. I merely translated it.
