If you want to have a chance to win a $50 GameStop gift card courtesy of The Witcher 3: Wild Hunt, all you have to do is to explore the world.
To be more precise, you’ll have to explore the world of Google Maps looking for monsters from the game. Clicking on them will let you see if you’re the first that found each critter. If you are, you win.
To participate you need to go here, log in with either Facebook or Google, then go in the street view of Google Maps and start searching.
As you may imagine, the contest is open only to residents of the United States.
PS: Some monsters don’t catch shadows on Google Maps. Downgrade!
