Official announcement for Rainbow Six Siege from Ubisoft, published on Steam on September 23, 2026.
See everything included in the Y11S3.1 update.
REFINEMENT CHANGES
These are small adjustments that don’t aim to alter an Operator’s overall power level or flexibility. Instead, they focus on polishing gameplay details, improving consistency, and enhancing quality-of-life without shifting the meta. Our goal is to maintain a steady stream of these refinements alongside major updates, helping the game evolve and improve at a constant pace.
BUCK
This allows Buck to maintain his presence for longer, enabling more consistent vertical play and extended utility usage throughout the round.
SKELETON KEY
- Total ammo increased to 36 (was 31).
CASTLE
This increases the time and commitment required to clear Castle’s barricades, improving their role in slowing Attacker advances and reinforcing defensive positions.
ARMOR PANEL
- Increased melee hits to destroy the Armor Panel increased to 10 (was 9).
FENRIR
We want to improve the responsiveness of his gadget when triggering zones. This allows Fenrir to influence engagements more quickly, improving his ability to react to Attacker presence and apply pressure in dynamic situations.
F-NATT DREAD MINE
- Reduced the time it takes for gas to reach maximum range to 1.9 seconds (was 2 seconds).
MAESTRO
We aim to improve the consistency of his gadget over time.
EVIL EYE
- Increased the battery life to 9 seconds (was 8 seconds).
THERMITE
This change improves the lethality of Thermite’s charges when activated in contested areas, increasing the risk for Defenders playing close to reinforced surfaces.
EXOTHERMIC CHARGE
- Increased damage to 220 hp (was 200 hp).
SLEDGE
We want to improve Sledge’s responsiveness when using his gadget, allowing him to apply destruction more fluidly.
