What do we already know about Y11S4?
Ubisoft confirmed a lot in Community Checkpoint #6 on 2 November, which we covered in full in our Y11S4 Ranked map changes article:
- No more seasonal Ranked map rotations: Ranked moves to a "best of" pool of about 15 maps, including the nine used in pro play.
- Hostage and Secure Area return to Quick Match.
- 3v3 Arcade, the smaller-team mode from Operation Split Fire, comes back.
- A Testing Grounds event with Half Reinforcements, followed later by a Hostage rework.
- A TCSG nerf, and from Y11S4 the .1 and .3 patches ship fewer but bigger changes.
New operators, maps, the season's name and its launch date haven't been announced. Those are what the reveal is for.
What is the Osaka Major?
The Osaka Major runs from 6 November to 15 and is one of the key events on the road to the Six Invitational, with teams playing for qualification points. As well as Twitch Drops, Ubisoft is running match predictions (correct picks can unlock weapon skins and Alpha Packs), a limited Osaka Major Bundle and R6 Share team bundles.

Is Rainbow Six Siege free to play?
Yes. Quick Match and Unranked are free with a selection of operators. Ranked, Siege Cup, more operators and cosmetics need a purchase. It's on PC, PlayStation and Xbox. We'll update this page with everything announced at the reveal.
