The Ubisoft Club is giving away a free PC game in every month as of June to celebrate Ubisoft's 30th anniversary. First we obtained Prince of Persia: The Sands of Time in June. Then we got the original Splinter Cell in July and Rayman Origins in August. Actually, there will be three more free Ubisoft games till the end of 2016.
