Operation Vital Signal: Doc remaster lands December 1

Operation Vital Signal is Rainbow Six Siege's final season of Year 11, and it launches December 1. A remastered Doc leads the way. Ubisoft's official Vital Signal CGI trailer and the season reveal both dropped during the Osaka Major.

The reveal panel went live on November 14 at 6:30 PM PT. Ubisoft's Y11S4 reveal announcement also offered a free weapon charm through Twitch Drops for viewers. Doc is one of Siege's original operators, and his old Stim Pistol has been part of the game since the original Rainbow Six Siege release in 2015.

How does Operation Vital Signal change Doc?

The Stim Pistol is gone. In its place is the E-HEAL Monitor. The developer notes published by Bleeding Cool explain that Doc can remotely trigger patches already attached to teammates. That lets him heal allies and revive downed players from anywhere on the map without exposing himself.

Shacknews' hands-on with Vital Signal says patches are applied in the prep phase, so there is no aiming in the middle of a firefight. With the old pistol, shots on moving teammates were often wasted. Now Doc looks like one of the most important Defender picks. He can also use his own patches to recover when he is Down But Not Out.

New weapon and balance changes

The MBZ-19 adds a strong primary to the Defender side, available to Jäger, Warden and Thunderbird. Thunderbird's Kóna Station count rises to four, the cooldown drops from 15 to 10 seconds, and stations now cleanse stun and concussion effects. The ACS12 and TCSG12 shotguns lose some damage and magazine capacity.

Operation Vital Signal at a glance

• Release: December 1, 2026 (Y11S4)
• Platforms: PC, PS5, PS4, Xbox Series X|S, Xbox One
• Doc: remote heals and revives with the E-HEAL Monitor
• New weapon: MBZ-19 (64 rounds, 33 damage, 750 RPM)
• Ranked: separate Solo/Duo and Flex queues, level requirement cut from 50 to 30
• Maps: targeted Bank update, modernized Yacht, Favela and Tower

What changes in Ranked and on the maps?

Ranked is splitting in two. Solo players and duos get Ranked Solo/Duo, while bigger groups play Ranked Flex. Ubisoft says cross-queue matchmaking will keep queue times short. The account level needed for Ranked also drops from 50 to 30.

Bank becomes the second map to get a targeted update. A new entry point behind the building speeds up attacks and makes the second-floor site harder to hold. Yacht, Favela and Tower are also getting modernized. It is the biggest map shake-up in a while, and it recalls the Crimson Heist patch that reworked Border.

What else is in the season?

The season opens with Freeze for All: Permafrost, an eight-player free-for-all mode, and Grand Larceny returns in February. Winter Daily Rewards run from December 1 to January 15, with 20 rewards in total. Five are Celebration Packs, with Gold Dust and Glacier skins back alongside a new animated T-5 SMG skin. There is also a DOOM crossover.

Ubisoft is bringing back Testing Grounds from January 19 to February 2. This time players can try Half-Reinforcements, a Defender secondary gadget prototype. A new Social Hub overlay also makes it easier to manage friends and build squads.

What does it mean for players?

Vital Signal improves what is already there rather than adding a new operator. The Doc remaster makes healing far less risky, and a separate Solo/Duo queue answers a long-running request.
