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.

Install notes:
Unpack the zip somewhere, and run the setup. It will wipe the previous patch content, as well as gamedata, and bins directory from the game. So if you had modded files, make sure you back them up before you run the patch.Beware, mods created for previous patches will not work with this 2nd patch until mod makers make them compatible. We can not give support in this case.
