Rainbow Six Siege uses Seasons and Years to define their different content packs and title updates. There are four seasons per year, and March 2019 marks the beginning of year four. Players have the option of purchasing a yearly pass, but it is not necessary to access all content. All maps and updates are given to everyone for free, and new Operators can be unlocked with the currency earned in-game. The current Year 4 Pass and everything that comes with it is outlined below.
Year 4 Pass
The Year 4 Pass allows the holder to instantly unlock eight new Operators throughout the four seasons of Year 4. These characters will be available seven days earlier than those who do not own the Year 4 pass, and a bonus 8 Uniforms and 8 Headgear will be given for free specifically for these Operators. Additionally, the Year 4 Pass includes a bonus 600 R6 Credits and the Lava 6 Charm for all primary and select secondary weapons. And finally, Year 4 season pass holders will receive a 5% Renown Boost, 10% discount on all item from the in-game shop (Renown and R6), and a 0.3% boost on Alpha Pack increases until January 31, 2020.
