Ubisoft Montreal revealed additional details for Rainbow Six Siege Year 6, Season 4: High Calibre. The season introduces Thorn, a new defender operator that Ubisoft Montreal describes as a trapper.

"Thorn's gadget is called the Razorbloom Shell," Rainbow Six Siege game designer Dominic Clément said during High Calibre's reveal, which is embedded below. "It's a sticky device you can throw pretty much everywhere on the map and it's going to stick on pretty much any surface."

As seen in Thorn's reveal trailer, the Razorbloom Shell is a proximity-based gadget. Once placed, an attacker must wander into its range in order for the gadget to activate. Upon activation, the attacker has a brief window of opportunity to decide whether to push ahead, retreat, or destroy the gadget before it explodes. When used correctly, the Razorbloom Shell is designed to force attackers into panicking and moving without careful consideration, which can prime them for ambush.
