Ubisoft has released update 1.000.160 (version 3.54) for Rainbow Six Siege, primarily to resolve an exploit involving the operator Osa. The hotfix, deployed on October 22, 2026, across PC, PlayStation, and Xbox platforms, officially re-enables the operator for all game modes.
Osa Exploit Fixed and Operator Re-Enabled
The primary focus of this maintenance period was the resolution of an exploit that led to Osa being restricted. With the deployment of patch 1.000.160, Osa is once again available for selection in the operator roster. In addition to the character-specific fix, the update addresses general gameplay performance and stability.
Seasonal Context: Operation Split Fire
Rainbow Six Siege is currently in Year 11 Season 3 (Operation Split Fire). This hotfix serves as a stability update within the current season’s lifecycle. The preceding season, Year 11 Season 2 (Operation System Override), established several core components of the current game state, including:
- The introduction of the Calypso Casino map.
- A rework for Dokkaebi’s Jegeo Payload.
- The launch of Ranked 3.0, an update to the competitive matchmaking and ranking system.
Players on PlayStation 5 will see the version number 1.000.160, while the update is identified as patch 3.54 on other platforms. For historical context on the features introduced earlier this year, you can review the Operation System Override details via Ubisoft.
