Ubisoft is deploying a test server for Rainbow Six Siege's next major update, Operation White Noise, early next week, but before then, players who have yet to try the popular shooter will have a chance to sample it for free. Today, Ubisoft announced that Rainbow Six Siege will be free to play on PS4, Xbox One, and PC via Uplay and Steam for a limited time this weekend.

The free period kicks off on Thursday, November 16, and runs through November 19. As is typically the case, PS4 players will need to have a PS Plus subscription in order to take part in the free weekend, while Xbox One owners will need to have an Xbox Live Gold membership.
