More fixes and features are coming in Rainbow Six Siege, as Patch 2.1 goes live for PC players today and February 16 for console players. The update brings a sizable list of new fixes, tweaks and additions with the most prominent being the ability to create 10-player custom games on dedicated servers. The Spectator Camera feature is also being made available on dedicated servers, enabling an 11th player to join in and observe custom games.
The full list of updates is extensive, including tweaks that range from a change in head and shield size for Blitz (making it harder to score a headshot around his shield) and Daily Challenges that accumulate even if players don't log in every day to the closing of assorted level exploits and glitches. For a full rundown, take a look at the Rainbow Six Siege forums.
