I've noticed that for me the GOGDownloader can't save FEAR 2 to memory, It can download it but if I restart the downloader it "forgets" FEAR 2 was on the list, thankfully it does seem to pick up where it left off if I go to my shelf to redownload it..

I had some issues with one of the files being corrupt Just downloaded it normally without the GOG Downloaded and no problem.

As far as I know that issue has been fixed.

I downloaded F.E.A.R. 2 thrre times with my Browser (Firefox) and each time the installer tells me, that all for *.bin files are corrupted and i have to download them again. So, the problem of broken downloads (no matter if GOG-download-tool or nor) is not fixed yet.

Edit: Tried it again with the GOGdownload-tool and it worked now.

It was apparently a problem with the 4th bin file.

They could also add Armacham Field Guide that was bundled with pre-orders and other editions of F.E.A.R. 2: Project Origin.
