Tom Clancy's Rainbow Six Siege Y9S1 Patch Addendum Fixes Bugs

Tom Clancy's Rainbow Six Siege releases a Y9S1 patch addendum detailing bug fixes across gameplay, level design, and operators, alongside download sizes for all platforms.

Ubisoft has released a patch addendum for Tom Clancy's Rainbow Six Siege Y9S1, outlining bug fixes for gameplay mechanics, map geometry, and operator interactions across all platforms.

Gameplay and Weapon Fixes

Fixes address issues where aiming down sights while holding a shield and handgun was too fast, Bailiff 410 damage decreased with a laser sight equipped, and the AK-74M missed its ACOG attachment. Friendly fire penalties erroneously given during Free For All matches are also resolved.

Map and Level Design Fixes

Numerous level design fixes address unintended lines of sight, collision errors, and spots where players or drones could get stuck or navigate out of bounds across maps like Clubhouse, Lair, Nighthaven Labs, and Kafe Dostoyevsky.

Operator Adjustments and Fixes

Doc no longer allows instant self-revives when shooting players wearing Rook's Armor. Deimos receives multiple fixes for his DeathMARK Tracker, ensuring correct target selection, ping visibility, and proper behavior when Deimos is eliminated during activation.

Why this patch matters

The Y9S1 addendum cleans up lingering issues with operator gadgets, map geometry, and weapon attachments.
