New Rainbow Six Siege Y6S4 Operator: Thorn

Of course, a new season of Rainbow Six brings a brand-new Operator and in Operation High Calibre, it’s Thorn.

Thorn is the Rainbow Six Siege’s 31st Defender, and also the 62nd Operator overall. Hailing from Ireland, Thorn brings the brand-new UZK50Gi SMG and the Razorbloom Shell Unique Ability.

The Razorbloom Shell “sticks to a surface after it’s thrown by Thorn” and once it’s triggered, it “automatically propels a set of sharp blades in all direction,” killing anyone nearby. Thorn can also run a Deployable Shield or Barbed Wire Gadgets, the M870 Shotgun, and the 1911 TACOPS or C75 Auto handguns.

Outback, set in Australia, has also undergone renovations with the Y6S4 update. Bomb sites have been moved and both the main building and exterior have been modified “to allow Attackers to create and execute more effective strategies.”

Also, the devs explained that “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.”
