GOG.com has officially kicked off its annual Autumn Sale, offering steep discounts as high as 85 percent off its catalog of DRM-free PC games. Along with those discounts, you can get The Witcher 2 for free - but you'll have to jump through a few hoops first.
In order to get the free game you have to collect stamps each day by visiting the site. There are seven stamps that you have to collect and a new one will appear every day. Those who are ultra cheap and do not already own the CD Projekt RED title won't have to purchase anything in order to get the game for free.
