What is the Ubisoft Club? The Ubisoft Club rewards players for their engagement within the games. It is free and rewards its members just for playing Ubisoft games however they have acquired them: purchase, second hand, Console service like PlayStation Plus or Xbox Live Go.

To sign up you just need to have a Uplay account. If you don't have any Uplay units (the currency needed to unlock these rewards) don't panic. Rainbow Six Siege has some pretty easy and straightforward tasks than you can do when the game comes out! Here is a screenshot of the challenges - http://imgur.com/Bkgdp2S

Ps. The wallpaper pack is REALLY good. Here is a preview of the SAS one! http://imgur.com/z9ATGzs
