Hey fellow gamers and freebie seekers!
The Witcher: Enhanced Edition is free from GOG.
It was previously free (link), but had a lot of unnecessary steps to get it in the previous giveaway, so many people didn’t bother. 
It is easier to claim this time around.
Game Description:
Your name is Geralt of Rivia and you are a witcher, that means you kill monsters for a living. You were given special training to be the best at what you do and your body has been enhanced with potent elixirs to help you do it.
Suffering from amnesia you remember nothing of your past. Kaer Morhen, the last remaining keep of the witchers, was attacked by a mysterious organization, just as you were starting to lick your wounds there. The battle is won but the secret recipe for the mutagen, a substance required to create more of your kind, has been stolen. The surviving witchers set out to find and reclaim it and punish everyone involved. Memory loss or not, you are one of them.
