Rainbow Six Siege‘s Y6S4 High Calibre was fully revealed yesterday, and it is bringing some exciting changes to the game.

The last season of this year is introducing Rainbow Six Siege’s 62nd operator ‘Thorn,’ who is bringing an explosive trap gadget called the ‘Razorbloom Shell’, alongside a new SMG called ‘UZK50GI‘. Apart from this, the game also gets some balancing changes that you might love or hate.

One change that has already created mixed reviews is that defender cameras now lose signal after 10 seconds when they are outside the map. So, Valkyrie mains will surely be disappointed as their cams (thrown outside the building) now won’t be able to feed intel for more than 10 seconds. However, this will also alleviate some major frustration for beginner players, spending a major chunk of time outside the building.

Outback has received a variety of updates to improve balancing and player comfort. Both the main building and its exterior have been modified to allow Attackers to create and execute more effective strategies. As well, new exterior soft walls have been added to the building, and some areas have been refurbished and cleaned up to remove junk and provide better lines of sight and balance.

A few new locations have been added to the map:

  • 1F Convenience Store, 1F Compressor Room, 1F Gear Store, and 1F Beer Fridge have been combined into 1F Bike Repair and 1F Mechanic Shop.
  • 2F Office Supply is larger and has an exterior soft wall.
  • 1F Restaurant has been split into two rooms: 1F Restaurant and 1F Shark.
  • 2F Covered Terrace is now an interior area that connects 2F Mezzanine and 2F Piano Room. The 2F Piano Room stairs have been removed.

Bomb sites have been moved:

  • The bombsites that were previously in 2F Dorms and 2F Laundry have been moved to 2F Laundry and 2F Piano Room.



  • The Test Server will now only be open at three separate times throughout the season and content will be split into three different releases.
  • Season Release: Contains only content that will ship for the season.
  • Lab Release: Contains experimental content and will be used by the team as an opportunity to collect feedback on features that are still in early production.
  • Balancing Release: Contains Operator and other balancing changes.

R6 FIX 2.0

  • R6 Fix has received a variety of extensive updates. The website’s UI and UX design has been completely overhauled, and the function of various features, such as the search feature, has been brought up to date. In addition, a new notification system now allows users to track updates to reports, and to provide even more transparency, devs now have the ability to communicate directly with users.


Since the game’s release, Rainbow Six Siege has always used two colors to represent teams: blue and orange. The default team colors have now changed to blue and red, with opponents always being red. This change is mainly reflected in the UI and round feedback. It aims to bring consistency to the UI and improve onboarding for newcomers. The team colors can be changed between blue, red, or orange in the Accessibility section of the Options menu.

To go along with this change, teams are now referred to in-game as Your Team and Opponents instead of Blue Team and Orange Team.



  • Players can customize their Operator’s unique abilities in the Loadout section.
  • Players can navigate to any Operator in the Operators section and select the Appearance tab to view Headgear, Uniforms, Victory Celebrations, Operator Portraits, and Card Backgrounds.
  • Players can customize their Operator Cards by mixing and matching Operator Portraits and Card Backgrounds. Their selections will be seen by teammates before everyone loads into the match and in various places in-game. They will also be seen by opponents they eliminate.
  • UX and UI changes have been made to various customization menus to improve player comfort.


  • Players can now acquire Exotic weapon skins during their Battle Pass progression. These new weapon skins have a unique 3D effect.


As with every season, High Calibre brings a price decrease for specific Operators. Nomad and Kaid are dropping to 10,000 Renown or 240 R6 Credits, Kali and Wamai are changing to 15,000 Renown or 360 R6 Credits, and Aruni will now cost 20,000 Renown or 480 R6 Credits. Take this opportunity to add them to your roster and maybe you’ll find your new main!
