R6 Y11S4 (2026): Release Date, What's Confirmed, What to Expect

Rainbow Six Siege's next season, Year 11 Season 4, hasn't been announced. What is known comes from three places: the dates Ubisoft has published for the season that's running now, the things Ubisoft has said will start "in Year 11 Season 4", and the rules every Ranked 3.0 season follows. This page puts those together as of 2 November 2026, marks every date that's our estimate as an estimate, and leaves out the rumours. It will be rewritten when Ubisoft reveals the season.

When does Y11S4 start?

Ubisoft hasn't said. On 2 November 2026 its Rainbow Six Siege page still advertised the Operation Split Fire Battle Pass "from September 1st to December 1st", and its newest Siege posts were the Y11S3.2 patch notes (13 October) and the mid-season designer's notes (15 October) — nothing about the next season. Today is day 63 of Split Fire, and the pass ends in 29 days. Our estimate of an early-December start rests on three things, each of them checkable:

1. The pass marks the season.

   Split Fire launched on 1 September 2026, the same day its Battle Pass began, so the pass ending on 1 December is the best marker for the season's end.

2. Year 11 launches on Tuesdays.

   Season 1 began on 3 March, System Override on 2 June and Split Fire on 1 September — all Tuesdays — and 1 December 2026 is a Tuesday too.

3. Last year's Season 4 was revealed in mid-November.

   Ubisoft's ShieldGuard post of 7 November 2025 announced the Season 4 reveal panel for Sunday 16 November, and Ubisoft News published Operation Tenfold Pursuit the same day. The same rhythm would put this year's reveal about two weeks before the pass ends.

Our free season calendar carries the same projection, marked as an estimate, until Ubisoft confirms or changes it.

What Ubisoft has confirmed for Y11S4

Only one item is announced for the season by name. Ubisoft's Community Checkpoint recap of 7 August 2026 lists "A new, mandatory Code of Conduct beginning in Year 11 Season 4", noting that "the player code of conduct emphasizes no cheating or toxic behavior". Its text isn't published yet; it will sit beside the Core Rules of 31 July 2026, which our penalties and reputation guide explains.

Everything else that's certain comes from rules Ubisoft applies at every season start, or from promises made for "next season":

• A rank reset with placements: "At the start of each season, all ranks will be reset and players must complete 5 placement matches to receive a new one."
• Split Fire's rank rewards: the seasonal charm and card background for the highest rank you reach "are delivered at the start of the next season".
• The Legend Division top 100: "those who crack the top 100 get a charm next season that displays their final leaderboard position".

Name, operator, map, balance changes and exact dates: not announced. Reports about any of those before the reveal are rumours, so they aren't repeated here.

What the switch does to your rank

Ranked 3.0's season rules, in force since 2 June 2026, decide what happens on the day Y11S4 arrives — unless the patch notes change them:

One change is pending without a date: Ubisoft said in June that placements "will carry more weight in determining starting rank in future seasons". Whether Y11S4 is that season, the patch notes will tell. The placement matches guide covers the reset in detail.

The Legend Division after Split Fire

The Legend Division — a solo-queue-only playlist above Champion — opened in the middle of Split Fire, on 15 October 2026 by SiegeGG's report. Entry needs "current Champion rank and Platinum rank last season, a positive reputation standing, and completed security requirements": an authenticator app for two-step verification and, on PC, the ShieldGuard Secure Platform. Players lock a region for the season, and the top 100 carry a charm into the next season showing their final position, which "you can only keep … if you stay in the top 100".

What it looks like in Y11S4 isn't announced. When Ubisoft first described it, the entry rule was "Platinum or higher in Season 2, and Champion in Season 3"; if the same pattern holds, Platinum or higher in Split Fire would be the "last season" requirement next time — our reading, not a Ubisoft statement. The Legend Division guide has every requirement.

Year 11 so far

Season	Started	Operator	What it brought
Y11S1 Season 1	3 March 2026	Solid Snake	Solid Snake joins as an Attacker.
Y11S2 Operation System Override	2 June 2026	Dokkaebi	Ranked 3.0 (no hidden MMR), the Dokkaebi remaster and the Calypso Casino map.
Y11S3 Operation Split Fire	1 September 2026	Noor	Noor, a Defender built to counter shield operators; the Legend Division from mid-season.
Y11S4 not announced	≈ early December 2026 (our estimate)	—	A mandatory Code of Conduct; the rest at the reveal.

Year 11 has followed Siege's usual rhythm of four seasons of about three months each. The biggest change came in the middle: Ranked 3.0 arrived with System Override, removed hidden MMR and gave Champion five divisions like every other rank — the rules the Y11S4 reset will follow.

Security and conduct changes on the way

Ubisoft's August 2026 recap listed more work without tying it to Y11S4. Treat these as coming, not as dated:

• Anti-toxicity voice chat: "Updates to anti-toxicity voice chat programs before the end of the year".
• App-based two-step verification beyond Legend: "Eventually, two-factor authentication via app will be rolled out to other divisions of Rainbow Six Siege as well."
• A kernel-level anti-cheat: a team at Ubisoft Security "is working on a kernel level, shared anti-cheat solution across all Ubisoft games".
• Retroactive bans: a program "that can analyze past matches, so cheaters can be retroactively caught and sanctioned".

If you don't use an authenticator app yet, the switch is a good moment to add one: it's already required for the Legend Division. The ShieldGuard guide covers the PC security settings.

Year 12 and beyond

Ubisoft's Gamescom recap of 30 August 2026 gave the clearest look past Y11S4:

• "Starting in Year 12, Siege is going back to four new Operators per year."
• A Hostage Rework is in active development.
• Arcade: after the response to the 1v1 and 3v3 modes, the team is "looking at ways to take those experiences further in future seasons".
• A teaser: "A playable Operator is going to die." No operator or date was given.
• Conduct: "Year 12 will introduce features that recognize and encourage good behaviour" (7 August 2026).

On the economy, Ubisoft's post of 30 June 2026 says the Marketplace "will remain closed" while the economy is rebuilt, with no reopening date, and that from Season 3 "new event packs will transition to R6 Credits only". Nothing in it is specific to Y11S4.

How to get ready for Y11S4

1. Lock in your Split Fire reward.

   Your highest rank before the switch is your reward rank — aim for it before the pass ends on 1 December 2026.

2. Plan your placements.

   Five games with bigger RP swings and no squad limits: play them rested, on operators you trust, with your strongest friends.

3. Check your Ranked access.

   A premium offer, level 50 and two-step verification — the unlock guide walks through them.

4. Read the patch notes on launch day.

   New operator, map pool, balance and any placement change all land there.

5. Learn the new Code of Conduct.

   It's mandatory from Y11S4 — know what it asks before your first match.
