FULL REVEAL - Operation High Calibre

Rainbow Six Siege's next major update is set to be fully revealed in a matter of hours.

According to Ubisoft, we should find out everything we need to know about Operation High Calibre and what's coming to Rainbow Six Siege in Y6S4 at the following times:

• 10:00 November 8th PST
• 13:00 November 8th EST
• 18:00 November 8th GMT

There's going to be a new Operator - revealed as Thorn - and a new weapon. Rumours also suggest that Outback - which was first added to Siege in 2019 - is going to be the newest map to get a major overhaul.

This Operation High Calibre full reveal should confirm the new Operator as Thorn - offering information about their unique gadget and loadout - and confirm the rumours that Outback is being reworked.

We're not expecting any pre-season Designer's Notes yet, though - these are essentially a set of Patch Notes. However, they offer more than just value changes. Siege also offers in-depth analysis from the development team through these notes.

We don't know exactly when Y6S4 is set to start for Rainbow Six Siege - however, it should drop a short period after Crystal Guard ends. So, we're expecting sometime in a two-week period in late November and early December. It could drop on November 30th or December 7th.

Keep an eye on Rainbow Six Siege's socials for the latest information and confirmation of the release date for Operation High Calibre.
