Rainbow Six Siege X is a tactical first-person shooter from Ubisoft Montreal, published by Ubisoft. It is the June 2025 relaunch of Tom Clancy's Rainbow Six Siege, which first shipped on 1 December 2015, and it runs on the same client: attackers and defenders contest a site inside a building whose walls, floors and ceilings can be opened. Every fact on this page comes from the publisher's own pages, read on October 12, 2026.
Game Facts
Developer, publisher, first release date and genre: the Steam store page, read October 12, 2026. Siege X launch date and the operator and map counts: the publisher's own pages, read the same day. The 43 operations are the third-party tracker's record, described under Seasons below.
Background
The original game shipped on 1 December 2015 without a season system. The operation cadence began two months later, on 2 February 2016, with Black Ice, and has run roughly quarterly since. The publisher's own launch article for Siege X describes the 2025 update as "a new evolution of the intense tactical shooter", with major upgrades to core systems, revamped player protection systems and the permanent 6v6 mode.
Siege X was a free update for players who already owned the game, and the same article states that existing players keep their content and progression. Alongside it the publisher opened free access, which is the change that matters most for anyone arriving now: it is covered under How the Game Works.
How the Game Works
The publisher's map directory groups the playable maps under four playlists — Ranked, Unranked, Quick Match and Team Deathmatch — and the launch article adds Dual Front, a permanent 6v6 mode that the publisher describes as launching with Siege X and that runs on current-generation consoles and PC only.
What free access covers. The publisher's launch article lists Quick Match, Unranked and Dual Front, with a selection of operators, as the modes a new player can enter without paying. Ranked, Siege Cup, and the remaining operators and cosmetics require payment to unlock. That split is the publisher's own description of its own access model, and it is the reason free access and the paid game are worth telling apart on a page like this one.
The operator system. Each operator carries one unique ability and a fixed loadout of two primary weapons, two secondary weapons and two gadgets, and is filed on one side of the match. The roster stands at 78 operators in the publisher's own directory — 39 attackers and 39 defenders — each with a published set of specialties and a three-point rating for health, speed and difficulty.
Guides
Two sections, both built from the same read.
All 78 operators
The full roster split by side, with each operator's official specialties and ratings, and a page of their own for every one of the 78 carrying the ability, the loadout and the record fields.
Every operation since 2016
All 43 operations with start and end dates, from Black Ice in February 2016 to the live season.
The Maps
The publisher's map directory lists 27 maps as of October 12, 2026. They are named here in alphabetical order rather than by playlist, because a map's playlist is a rotating decision and a name is not:
| Maps in the publisher's directory |
|---|
|
Map names: the publisher's own map directory, read October 12, 2026, where the counter reads 27 of 27. The directory filters them by playlist; that filter is not reproduced here because it moves between seasons.
Official Channels
- Rainbow Six Siege — the publisher's own site — the source for the launch article, the operator directory and the map directory used above.
- Rainbow Six Siege on Steam — the store page the developer, publisher and first release date were read from.
- Rainbow Six Siege X launches today — the publisher's own announcement of the relaunch, free access and Dual Front.
We link these publisher channels without nofollow because we have opened them and we do stand behind them. The season tracker cited on this page is a third-party record rather than a publisher statement, and is linked with nofollow.
Update Rule
Rainbow Six Siege X is a live game, and this page tracks the publisher's own pages rather than trying to keep pace with every patch. Roster counts, the map list and the free access split are re-read from those pages when this page is revised; the operation dates stay attributed to the tracker until the publisher publishes a full history of its own. The date at the top records when these sources were read, not when the game last changed.
