Tom Clancy's Rainbow Six Siege: North Star is the twenty-first Season update for this tactical shooter, continuing its episodic evolution. This update introduces Thunderbird, a new Operator from Star-Net Aviation, whose unique Kóna stations can heal or even revive downed allies, though enemies can also use them. Gameplay is further altered by a significant rework to the Favela map. As a seasonal addition, it refines the established high-stakes combat meta across PC and consoles by adding new strategic utility.
