Note that, despite what the main screenshot says, as well as the names on the downloaded files, this is NOT the "Collector's Edition" - you can confirm this by reading the "RAZOR.nfo" file, inside the archive.

Fortunately, the "Collector's Edition" is on IGG-Games, but on a different page, here:

Fright Chasers 3 - Director's Cut (Collector's Edition)

You can also tell by the file size difference, this one is just 458mb while the "Collector's Edition" is 637mb.
