It's fair to say Year 9 transformed Rainbow Six Siege. Ubisoft's efforts were put on improving rather than inventing. Meanwhile, players also welcomed brand-new features like the Siege Cup, crossplay between PC and console, and the two new operators Deimos and Skopós.
In terms of cosmetics, Ubisoft also made crucial changes. After adding the Marketplace, the team added the Membership system to give exclusive items to Rainbow Six Siege players. If that wasn't enough, Ubisoft also made changes to the cosmetics given in time-limited game modes, introducing the re-colored and the Memento weapon skins.
For those unaware, Memento weapon skins are legendary weapon skins that can only be claimed after having unlocked all of the cosmetics included in a time-limited game mode. These weapon skins are animated and full of details that makes them one of the best gun cosmetics in the game.
Due to the exclusiveness of these weapon skins, getting them is very expensive. With time-limited event collections including 33 items, players can choose between purchasing the required items with 8,910 R6 Credits or 371,250 Renown. With 7,590 R6 Credits being worth USD$49,99, Memento weapon skins should be valued at around USD$60 and USD$65.
In Year 10, Ubisoft released the first Mythical Memento weapon skins. Introduced in the Rengoku Event, Ubisoft added a new one in this year's MUTE Protocol.
Despite the price, many players want to get their hands on them. Memento weapon skins aren't just exclusive; they are great looking skins too. If you're a die-hard Rainbow Six Siege fan, we're sure you want them at all costs.
