The beloved Rainbow Six Siege Containment event is back this year with brand-new cosmetic items and a fun game mode. Inspired by the popular Outbreak event released in 2017 with Operation Chimera, it delivers a similar structure of gameplay in the 5v5 event mode. On the attacking half, you can pick from seven selected attackers who will hunt down the rest seven infected defenders, and destroy nests in the pre-reworked Consulate.If the defenders successfully defend the nests, they win. On the other hand, attackers can utilize various tactics to breach through their defenses. While the 5v5 game mode is a fun way to enjoy the event, the Containment packs can also deliver some fascinating cosmetic items which you can grind through either R6 Credits and unlock the bundles, or use in-game renown to purchase the packs.Complete list of Rainbow Six Siege Containment event cosmeticsMuch like most events, Containment in Rainbow Six Siege also offers cosmetics for weapons, headgear, uniforms, operator portraits, weapon charms, card backgrounds, attachments, and drones.
