Ubisoft is making some big changes to the way fans buy Rainbow Six: Siege, and what it means for their in-game unlocks.

Right now, Siege has five different versions that players can buy that all offer slightly different amounts of content unlocked from the start. The rest of the game’s content is available to all players via Siege’s in-game currency, called Renown, which can be earned by playing matches.
