Ubisoft has today revealed Rainbow Six Siege Y6S4 (Year 6 Season 4) High Calibre! This new season once again introduces a new Operator in Thorn, a reworked map, Operator changes and more! Thankfully, Ubisoft invited MP1st to check out the new Operator and map reworks, and we have a load of gameplay available below!

Rainbow Six Siege Y6S4 High Calibre New Operator, Map Rework, and Gameplay:

In Rainbow Six SiegeY6S4 High Calibre, players will be able to play as new Defender, Thorn! This new Operator is equipped with Razorbloom Shells: throwable proximity devices that, once triggered, initiate a timed detonation. If enemy players don’t get out of the area of effect on time, they will receive damage at the end of the fuse timer. Thorn is a medium speed, medium armor Operator who can be equipped with either the new UZK50Gi or the M870 as primary weapon and with the 1911 TACOPS or the C75-AUTO as secondary weapon.

Check out the reworked Outback map, which has been rebuilt to “improve balancing and player comfort” according to Ubisoft. “Both the main building and its exterior have been modified to allow the Attackers to create and execute more effective strategies. In addition, 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.”


Additional updates coming with High Calibre include:

  • Choosing team colors between blue, orange or red
  • Balancing updates (Finka, Echo and Mozzie’s drones, bulletproof cameras update, new rule for cameras placed outdoors)
  • New customization features on Operators’ Cards, victory dances, colors and more.
