Ubisoft has officially unveiled the full details for Rainbow Six Siege Year 11 Season 2, titled Operation System Override, confirming the return of a legendary franchise location and a substantial mechanical overhaul for one of its veteran operators. Dropping on June 2, the upcoming expansion centers heavily on tactical nostalgia by reintroducing the Calypso Casino map, a fan-favorite environment originally featured in Tom Clancy’s Rainbow Six Vegas and its sequel.
The reimagined casino level has been rebuilt from the ground up to fit the destruction physics and close-quarters structural design of Siege. Revealed over the weekend during a major competitive event in Salt Lake City, Utah, the map represents a deliberate callback to the franchise’s single-player and tactical roots. Alongside the new venue, Ubisoft is deploying visual and lighting enhancements to three existing maps: Emerald Plains, Kanal, and Outback.
Beyond the map roster changes, the core gameplay balance will shift dramatically with a comprehensive remaster of the attacking operator Dokkaebi. Her original Logic Bomb camera-hacking ability is being replaced by the Jegeo Payload, a malware gadget that targets an individual defender’s phone. If the affected player fails to disable the device in time, the phone detonates, inflicting 40 horsepower of direct damage and igniting a localized fire that can harm both the target and nearby teammates. To offset this lethality, the gadget features a shorter duration but offers quicker cooldown periods and more charges.
The update further introduces the XK23 assault rifle as a selectable primary weapon for Dokkaebi, Sens, and Ram. Players can also expect Ranked Overhaul 3.0, a major balancing pass that extends the gadget ranges for Pulse, Mozzie, and Nomad, and enhancements to Gridlock’s Track Stingers. Console players will receive native mouse and keyboard support later in the season. Operation System Override follows a high-profile Year 11 launch that crossed over with Konami’s Metal Gear series, signaling Ubisoft’s continued aggressive content roadmap for the long-running live-service shooter.
