Lost Alpha is a new episode of the S.T.A.L.K.E.R. series made by dezowave group for free!
Here is the long awaited third patch for S.T.A.L.K.E.R.: Lost Alpha. Due to the changes in storyline and engine, it's required to start a new game after you installed this update. Your previous saves made with 1.3002 will not work. This patch is cumulative, so you will not need to install the previous (1.3001 or 1.3002) patch at all.
