One of the best side bonuses of modern PC gaming is the fact that new games tend to just materialize in your digital distribution account of choice. I couldn’t tell you how I got this copy of Serious Sam 3 if my life depended on it, but I’m sure glad it’s there. Now Ubisoft are offering to expand your library even further as a little holiday gift, and all you have to do is log into Uplay. Okay, I realize you might be entirely keen on adding Ubisoft’s long-maligned digital distribution service to your regular rotation of game clients, but at least hear ‘em out. Starting now and lasting until December 11, you’ll be able to grab a free copy of the excellent alt-history RTS World in Conflict, along with its Soviet Assault expansion. Then, from December 12 through December 18, you’ll be able to pick up the pirate-themed Assassin’s Creed IV: Black Flag for free. You can even pretend you’re pirating it if that makes you feel like more of a high seas scallywag.
