A lot is changing in Rainbow Six Siege: not only will it's third season usher in a cooperative zombie mode,  but what you get when you purchase the game will be different, too. In a new blog, Ubisoft has announced it will remove the Renown cost for the game's original 20 operators. This applies to owners of the Advanced, Gold and Complete Editions, and will take effect March 6.

Meanwhile, the Starter Edition, which previously offered two random operators to those who purchased it, will now offer six random operators. These random selections are drawn from a pool including Ash, Thermite, Thatcher, Fuze and Sledge from the attackers side, and Rook, Mute, Smoke, Jager and Kapkan from the defenders side.
