Installation:

1. Make sure that you have installed SoC in 1.0004 version. Mod was made on this patch so you should install game on this version. If you don't have 1.0004 game version, use from "1.0006 to 1.0004 downgrader" which you can find in "Tools, Add-Ons" directory in the downloaded package. Then remove old Gamedata's and other mods from your Stalker's directory.

2. Unpack S.T.A.L.K.E.R. - Secret Trails 2 + Autumn Aurora 2 (English, 12.06.2014).7z and move Gamedata and Bin directories to game directory.

3. Use the User.ltx file from the package (put it to localization where saved games/logs are located).
You can also add -noprefetch and -nointro to the game shortcut to make loading times faster.
