Rainbow Six Siege Y6S4 High Calibre is releasing today! Downtime for maintenance will begin later today and as with any update, a small period of maintenance is required for each platform before the new season can begin. The server downtime is planned to last one hour, however, as with any server downtime, this could vary.

Writing on Twitter the team told fans that the deployment schedule will start with PC players, then PS4/PS5 owners and finally Xbox users.

PC server downtime begins at 9:00 AM ET / 13:00 UTC. For those in the UK that means a 1pm GMT. Xbox server downtime begins at 10:00 AM ET / 15:00 UTC. That means UK based players will go offline at 2pm GMT. PS4/PS5 server downtime starts at 11:00 AM EDT / 16:00 UTC. Finally that means Xbox players will go offline at 3pm GMT.


Ubisoft has confirmed that the Rainbow Six Siege Y6S4 update and patch will be quite a small one. Approximate files sizes can be seen below:


  • PC - Steam: 4.80 GB, Uplay: 5.36 GB
  • PS4 - 4.38 GB
  • PS5 - 4.10 GB
  • Xbox One - 4.08 GB
  • Xbox Series X - 4.31 GB

Y6S4 Designers Notes

Before we get to the patch notes, we also want to recommend that players take a look at the latest notes from the dev team. The recently released Y6S4 Designer's Notes go into far more detail than the patch notes. For instance, one of the big changes in Y6S4 is a change to the Angled Grip weapon attachment. Here's a quick recap of the change:

  • The increase to ADS speed provided by the Angled Grip is now 20% less than it was before.

Now, whilst the patch notes will give you the above intel, what it won't tell you is why? That's where the Designer's Notes come in.

In the case of the Angled Grip, we learn not only who the change is targeting, (in this case Top Ranked players and Pros), but also a deep dive into the change itself. Here's a small snippet of what to expect:

Before we get into the description, we want to acknowledge that we know this isn't going to be a popular change. We all love the angled grip, but that's part of the problem - it's so effective that it has become an essential attachment in just about every case. We know that by changing this, it will have an effect that's felt throughout the game, so we ask you to please jump on the Test Server, give it a try, and then come to us with your thoughts. In theory, it's a big change - we know that - but we truly want to understand how you feel with it in practice. This is something we can and do plan to continue tweaking, so we're extremely open to hearing your thoughts, as always.

Rainbow Six Y6S4 Patch Notes - Operation High Calibre

R6 Y6S4 | Test Server Patch Notes


Since the game's release, Rainbow Six Siege has always used two colors to represent teams: blue and orange. The default team colors have now changed to blue and red, with opponents always being red. This change is mainly reflected in the UI and round feedback. It aims to bring consistency to the UI and improve onboarding for newcomers. The team colors can be changed between blue, red, or orange in the Accessibility section of the Options menu. To go along with this change, teams are now referred to in-game as Your Team and Opponents instead of Blue Team and Orange Team.
