Rainbow Six Operation High Calibre, the final update for Year 6, is arriving. The new operation includes defender Thorn, the Outback map rework, balance changes to Finka, Mozzie, and more ⁠— here are the full patch notes of the Y6S4 changes.

Rainbow Six is rounding out its big anniversary year ⁠— the sixth one, of course ⁠— with a bang in Operation High Calibre. It’s in the name after all.

The update will include new content such as Thorn, the game’s 62nd operator, and a rework to Australian map Outback. The existing members of Team Rainbow aren’t forgotten though, with balance changes to Finka, Valkyrie, and more.


Plus, the game’s HUD is getting a visual overhaul, and the Test Server is undergoing some changes too.

Here’s what you need to know about Operation High Calibre with the full patch notes right here.


Operation High Calibre is the final big update of Rainbow Six Year 6.

When is Rainbow Six Operation High Calibre launching?

Rainbow Six Operation High Calibre is set to go live on November 30, 2021.

After a three-week testing period which started on November 8, the update will be shipped everywhere, so you don’t have to wait long to get your hands on all the new content.

What’s coming in Rainbow Six Operation High Calibre?

New defender Thorn brings Razorbloom Shells

Thorn, Rainbow Six’s 62nd operator and 31st defender, is rounding out the new additions to Team Rainbow in Year 6. The Irish defender brings a new weapon into the Siege arsenal in the highly-destructive UZK50GI.


Her gadget is called the Razorbloom Shell, which sticks to a surface after it’s thrown. It lays dormant until an enemy walks by, triggering an explosion after a short timer that shreds enemies caught in its radius ⁠— one trap can kill an entire squad if not dealt with.

The Shells can be shot, even during the activation time. However, when combined with Barbed Wire, or utility like Melusi’s Banshee, the Razorbloom can deal a ton of damage. Check out our Thorn guide for more.

Outback map rework overhauls Australian motel

Outback, which first released as part of Year 4’s Operation Burnt Horizon, is getting a full map rework in Operation High Calibre.


Every aspect of the Australian motel-based map is getting overhauled. The general plan though is to give attackers more creative options to breach into sites, with new external walls and a bit more destructibility across the map.

The map has also been decluttered, bomb sites shifted around, and new rooms added ⁠— like the Terrace between Mezzanine and Piano Room making for a new top floor rotate instead of solely funnelling through Games Room.

Planned Defender camera nerf delayed

The biggest balance change planned for Operation High Calibre was a big nerf to defenders like Valkyrie. Defender cameras were set to automatically disable when thrown outside after a set period of time.


However, after testing on the TTS, Ubisoft are shelving the changes for a future update.

“On the [test server], we discovered an issue that will take longer to fix than expected, so we’ve decided to delay this change,” developers said on November 24.

With the changes in place, you could only set up cameras for 10 seconds outside before they were disabled, with no feed going back to the defenders inside. The change was a big nerf for Valkyrie especially, who relied on outside cameras on certain maps to gain key intel.

However, the changes have been delayed until after the Six Invitational 2022 at the earliest, giving Ubisoft time to fix map issues to make sure cameras are disabled properly.


“We’re updating our interior and exterior detection volumes, making sure they’re precise. This means going over every map and possible cam location, making sure there are no exceptions. This is why the change requires a little time.”

Buffs to Mozzie and Echo — increasing their camera activation times outside from three seconds to 10 seconds — will still be shipped.

Finka buffs let her revive herself when downed

French attacker Finka is leading the balance changes for the other side of Team Rainbow ⁠— and it’s a long-awaited buff at that.

She can now use her Adrenal Surge gadget to revive herself when downed, if she has a charge. The recoil boost has also been removed from the charge, which will be helpful for players who have mastered their spray patterns with the Spear (or other rifles).

However, to compensate for the power of the revive, she has an increased 20-second cooldown between Adrenal Surge charges.

There are also a host of changes coming to the Test Server, including some accessibility updates and an all-new in-game hub.
