Here’s how it works: whatever system or marketplace you already have The Witcher 3: Wild Hunt on, sync it up to GOG Galaxy.
To avail of the offer, you just have to sync whatever platform you already own one of the best RPGS on to GOG’s games library system, GOG Galaxy. If you already own The Witcher 3 on PC or console, you can claim a second copy for free from GOG for the next week.
