Ubisoft has rolled out new seasonal content for two of its Rainbow Six games, with Rainbow Six Siege and Rainbow Six Mobile both receiving major updates this week.
Rainbow Six Siege has launched Year 11 Season 2, Operation System Override, while Rainbow Six Mobile has kicked off Operation Gray Phantom on iOS and Android. Between them, the updates bring a new competitive map, a ranked overhaul, an Operator remaster, new mobile content, and a fresh set of limited-time events.
For long-term Siege players, Operation System Override looks like one of the more substantial seasonal updates in a while. The headline addition is Calypso Casino, the first new competitive Siege map since Year 8. Inspired by Rainbow Six Vegas, the map has been reworked for Siege’s current competitive standards, with a focus on vertical play, new entry points, and broader route options.
It is also being added directly into Ranked 3.0, which Ubisoft is positioning as a long-awaited rethink of the game’s competitive structure. Placement matches are returning, hidden MMR is being removed, and the overall goal is to make ranked progression clearer and fairer. For a game as punishing and tactical as Siege, clarity around ranking has always mattered, so this could end up being one of the season’s most important changes if it lands properly.
Remastered Operator
Dokkaebi is also getting a major remaster. The attacker has been reshaped into a more focused intel-denial Operator, with a new primary weapon, the XK23 assault rifle, helping push her toward a more aggressive role. Ubisoft says the changes are designed to make her more targeted and deliberate, rather than simply disruptive across the whole map.
Several existing maps are also being modernised, including Emerald Plains, Kanal, and Outback. These updates include visual changes and new destructible elements, while balancing changes are being made to Operators including Gridlock, Zofia, Nomad, Deimos, Solis, Pulse, and Mozzie.
Operation System Override also introduces rotating trial Operators, giving players access to a weekly set of six characters they may not currently own. At launch, the rotation includes Solid Snake, Maverick, Ace, Frost, Aruni, and Clash.
Elsewhere, Ubisoft is adding native mouse and keyboard support on console at mid-season, framed as part of its continuing push around competitive integrity and anti-cheat systems. Returning limited-time events Rengoku and M.U.T.E. Protocol will also appear during the season, while the esports tab is being updated with expanded visibility for Tier 1 team and player statistics.
Changes to mobile
Rainbow Six Mobile’s Operation Gray Phantom, meanwhile, adds Finka as a new Operator. Her team-focused ability is designed to boost combat momentum and encourage more aggressive coordinated play, making her a natural fit for players who prefer to push rather than sit back.
The mobile season also includes rotating 3v3 modes, a new event called Veil Protocol, themed challenges, fresh cosmetics, and a new Battle Pass with exclusive rewards. Ranked play is also continuing, giving players another chance to climb the ladder and unlock higher-tier seasonal rewards.
Between the two updates, Ubisoft is clearly treating Rainbow Six as a broader live-service franchise rather than a single flagship shooter. Siege remains the deep, competitive core of the series, but Rainbow Six Mobile is now being given its own seasonal rhythm, Operators, events, and progression hooks.
Operation System Override is available now in Rainbow Six Siege. Operation Gray Phantom is also live now in Rainbow Six Mobile on iOS and Android.
