Rainbow Six Siege Operation Vital Signal Arrives December 1
Ubisoft says Operation Vital Signal arrives December 1 with a Doc remaster, Solo/Duo and Flex Ranked playlists, the MBZ-19 and a Bank update.
Ubisoft has revealed Operation Vital Signal, the next season of Tom Clancy's Rainbow Six Siege, which arrives on December 1, 2026 with a remastered Doc, new Solo/Duo and Flex Ranked playlists, a new MBZ-19 and a Bank update. The studio announced the headline changes in a Steam announcement posted at 16:00 UTC on November 15, 2026.
The post, titled “Operation Vital Signal Revealed,” promises “a stronger Siege experience” and refers to the season as Year 11 Season 4. Ubisoft had scheduled the season reveal for the Osaka Major weekend, as we reported earlier. Here is what the post confirms for Rainbow Six Siege.
Doc gets the E-HEAL System to heal and revive from afar
According to Ubisoft, Doc “has been transformed into a true support specialist.” With the new E-HEAL System, he can remotely heal and revive teammates across the map, which the studio says opens the door to “fresh defensive strategies and clutch saves.”
The post does not describe how E-HEAL works, whether it has a range or cooldown, or whether Doc keeps his current gadgets. It also lists a new MBZ-19 without saying what it is or who uses it.
Ranked splits into Solo/Duo and Flex, unlocking at Level 30
Players will choose between Solo/Duo and Flex playlists for what Ubisoft describes as “a more tailored competitive experience.” Ranked access now unlocks at Level 30, which the studio says will help more players enter the fight.
Ubisoft does not say how many players can queue in each playlist, how ranks carry over, or whether the current Ranked system is replaced.
Bank is updated while Yacht, Favela and Tower get modernized
Bank receives “targeted gameplay updates designed to create new offensive opportunities,” according to the post. Yacht, Favela and Tower continue the Modernized Maps initiative with visual and gameplay improvements.
The announcement does not list the specific changes to any of the four maps, and no patch notes or download size have been published.
The current Battle Pass ends before Year 11 Season 4 begins
Ubisoft says the current Battle Pass “won't be available for much longer” and tells players to unlock the remaining rewards before Year 11 Season 4 begins. The post gives no exact end time for the pass.
Ubisoft has not announced a start time for December 1, a new operator beyond the Doc remaster, or pricing for the new season at the time of writing.
Tom Clancy's Rainbow Six Siege is a tactical first-person shooter focused on close-quarters combat between teams of five. Players select from a roster of operators drawn from counter-terrorism units around the world, each with unique gadgets and abilities.
