It's update day for Rainbow Six Siege and that means there's a new season starting in a matter of hours. Here's everything you need to know about what time the Y6S4 update is expected to drop and how much space you're going to need for it.

LATEST - Update Time & Download Size for Y6S4

Like Operation Crystal Guard, there's going to be an hour of Server Downtime for Operation High Calibre and the update will be available when it starts at the following times:

  • PC (Steam, Uplay, Luna, Stadia)
    • 06:00 PST / 09:00 EST / 14:00 GMT
  • Xbox (One, Series X|S)
    • 07:00 PST / 10:00 EST / 15:00 GMT
  • PlayStation (4, 5)
    • 08:00 PST / 11:00 EST / 16:00 GMT

You're not going to need to completely clear your hard drive for this one, either. You can find the download sizes for the update below:

  • Steam - 4.8GB
  • Uplay - 5.4GB
  • Xbox One - 4.1GB
  • Xbox Series X|S - 4.3GB
  • PlayStation 4 - 4.4GB
  • PlayStation 5 - 4.1GB

Operation High Calibre is going to introduce a new Operator, a visual overhaul for the HUD system, and some exciting changes to Elite Skin customisation and Exotic weapon skins. There's also going to be a minor Finka buff and a change to Camera and Gadget drones that should impact Mozzie mains particularly.

We have a set of Patch Notes for Operation High Calibre here, however, Ubisoft might release some updates when the Y6S4 update itself is available. We know for a fact that the camera changes aren't going to be live at the start of the season - so there could be some delays to the other changes coming in the next season.
