The best place to advertise an upcoming game is inside one of your current games, it seems. That’s what Ubisoft are doing with the latest Rainbow Six: Siege event, called “Containment”. The event is inspired by the upcoming Rainbow Six: Extraction, and gleefully messes with Siege’s set-up. It’s a PVP challenge where a team of Rainbow Six operators are pitted against a group of infected alien doppelgangers protecting their nests.
