Rainbow Six Siege

Rainbow Six Siege entered its eleventh year of live service in early 2026, making it one of the longest-running competitive shooters in gaming history. Ubisoft Montreal continues to deliver seasonal content drops with new operators, map reworks, balancing passes, and quality-of-life improvements.

Year 11 Season 1 launched in March 2026 with a new attacking operator, a full rework of the Bartlett University map, and significant changes to the ranked progression system including a new Emerald rank tier.

With over 70 operators spanning Attackers and Defenders, Siege's roster offers unmatched tactical depth. Each operator brings unique gadgets, loadouts, and playstyles that shape the competitive meta every season.

Siege's map pool rotates seasonally for Ranked play. Year 11 Season 1 features the reworked Bartlett University returning to competitive rotation alongside staples like Clubhouse, Oregon, and Coastline.

Rainbow Six Siege boasts one of gaming's premier esports circuits. The Six Invitational — Siege's annual world championship — features a $3M+ prize pool and draws millions of viewers worldwide.

Originally launched on December 1, 2015, Rainbow Six Siege was Ubisoft's bold bet on a live-service tactical shooter. After a rocky launch with server issues and limited content, the game grew into one of the decade's most successful multiplayer titles through consistent free updates, operator additions, and a thriving esports ecosystem.

Key milestones include the Operation Health initiative (Year 2) that prioritized stability over new content, the introduction of the attacker repick system (Year 7) that revolutionized competitive play, and the transition to a cross-platform ecosystem (Year 8) unifying PC, PlayStation, and Xbox player bases.
