Watch Dogs is now free on Ubisoft untill the 23rd of December. All you have to do is Login in on Ubisoft and claim it on your account :)

If you cant find it just search it in the store and you will see it right away.
Have a nice day and dont forget to grab a cold one!

Oh they also extended the time of AC Black Flag so you can also claim that one if you dont have that game yet
