Rainbow Six Siege Y11S2 Test Server Addendum Fixes Audio and Visual Bugs
Ubisoft released a patch addendum for Tom Clancy's Rainbow Six Siege addressing Test Server bugs, including missing operator voice-overs, lighting issues, and interaction blockers.
The latest patch addendum for Tom Clancy's Rainbow Six Siege cleans up a wide variety of audio bugs, lighting errors, and map interaction issues identified during the Y11S2 Test Server phase.
Gameplay and Map Fixes
Several crucial map and item bugs have been resolved. Dropped phones no longer emit a blinding flash when viewed from different angles. Defusers placed inside the bathtub on Fortress can now be properly picked up and defused even if the wall tiles above are destroyed. Additionally, only Solid Snake can pick up OSP Pouches dropped by fallen operators, restricting other attackers as intended.
Audio Corrections
Missing voice-over lines have been restored. Viperstrike now speaks correctly when talking with Nighthaven, and Thorn, Wolfguard, and Caveira now properly play dialogue when interacting with Denari. The patch also fixes missing destruction sound effects across surfaces and eliminates audio distortion caused by holding both lean buttons when set to hold.
Visual and UI Cleanup
A massive list of interface and lighting glitches has been squashed. Overly bright visuals have been toned down on Montagne and Osa's elite bundles, Solis's headgear visor, Twitch's Shock Drone laser, and dropped phones. Menu navigation no longer locks up after purchasing certain unlockable operators, and weapon charms no longer appear cropped in the locker preview.
Why this patch matters
This addendum resolves nagging quality-of-life snags from the Test Server, ensuring smoother audio cues and cleaner visuals ahead of the full Operation System Override launch.
