This is a full size Stalker stand-alone game. It can be downloaded directly from ModdB in 4 parts.
It extracts to a full 14.5 GBs and is much larger than the original Stalker Shadow of Chernobyl. It has many extra maps from the earlier builds directly received from GSC themselves with permission.
Download all 4 parts and put them in the same folder. Extract the part 1 and use it to extract and install the other parts and the game itself. You need a strong PC since they rebuilt the X-Ray engine enough to use multiple-cores and run better. Its still an old engine but looks very nice.
For any issues you might encounter, use the GSC Gaming World site which has new threads for this game.
When installing the progress bar just looks full, but its working fine and you need to wait about 15 to 20 minutes for it to finish.
