From Ubisoft's website:
New operators and a new map are coming to Rainbow Six Siege, and Ubisoft is celebrating by giving players free access to the game from November 11 to November 13. The free weekend will be available for the first time on PlayStation 4, as well as on PC through Uplay and Steam.
Operation Red Crow is set to launch on November 17 for PC, PS4, and Xbox One, marking the fourth major update for the game. It will include two new Operators (Hibana and Echo), a new map (Skyscraper), and new gameplay features. Season pass holders can play as the new Operators on November 17, and all players will be able to unlock them with Renown or R6 credits starting on November 24. As always, the new map and new gameplay features will be available to all players for free at launch on November 17.
