Rainbow Six Siege Y11S3.1 Buffs Buck and Castle in a Small Balance Pass

Ubisoft released Rainbow Six Siege patch Y11S3.1 (3.49) on September 22. Buck's Skeleton Key jumps from 31 to 36 total rounds, Castle's armor panel now soaks 10 melee hits instead of 9, and Fenrir's gas mines take slightly longer to reach full spread, up from 1.9 to 2 seconds. Ubisoft called it a polish pass with no intended meta shift. Rainbow Six Siege is a 5v5 tactical shooter built around destructible walls and gadget counters.
