This is limited to the PC version of the game, though. That said, it’s permanently yours once you claim it within this time frame.
Details below: — Ubisoft (@Ubisoft) April 17, 2019 For context, Assassin’s Creed Unity is the eighth entry in the franchise, and takes place in the city of Paris during the tumultuous period of the French Revolution. The game was riddled with a long list of glitches and bugs when it released back in 2014, but Ubisoft has since patched those issues. At any rate, be sure to claim your free game from Ubisoft via its giveaway page here. Of course, being the PC version of the game, you’ll need download Ubisoft’s Uplay game launcher to play it.
