Club Units are those fancy golden coins you get for completing challenges in various Ubisoft games. They are the points you remember you have because Far Cry has club-specific weapon unlocks and they can also be used to unlock discounts on the Ubisoft store. If you’ve been sitting on a pile of these points, you’ll want to pay attention to this post.
Starting April 1, and I do mean on April 1, Club Units are going to start to expire after two years and everything from March 31, 2017 and before is going to be gone. You can log in here to see how many (if any) points are going to be gone in a few days.
