Rainbow Six Siege's Official Release Date Set for October 13, 2015

From the announcement:

Selecting one of 20 Operators will be an important choice for all Rainbow Six Siege players. Will you focus on jamming the opposing squad’s communications? Or will you favor the ever-reliable bulletproof barricade? Will a ranged breach launcher be more useful to you than a sledgehammer? Every choice contributes to your team in different ways, and you can discover the possibilities when Rainbow Six Siege hits stores on October 13, 2015.
