Rainbow Six Extraction is a new co-op PvE standalone release coming January 2022 (check out our full hands-on preview here), bringing Left 4 Dead style alien parasite horde action to the tactical world of Rainbow Six. And to celebrate the upcoming release Ubisoft's Rainbow Six Siege is getting a special PvP Containment event starting tomorrow.

Which sees the arrival of a new game mode called Nest Destruction set in "a reworked version of the Consulate map overruled by the Chimera Parasite".

This event offers a look into the world of Extraction in Rainbow Six Siege, with a team of REACT agents (attackers) intervening to destroy Nests that are being defended by a team of Proteans, a deadly Archæan variant that can adopt the form of REACT operators (defenders) and mimic their behaviour with maximum speed and melee attacks. Defenders will be provided with additional Health, Aruni’s Punch, and Oryx’s special abilities, but will be weaponless for the whole game. Attackers will have a standard loadout without modifiers and only have access to a reduced Operator selection.

Containment will introduce a new game mode, Nest Destruction, that will have players fight over a Nest. Attackers will be given a two-tiered objective: destroy the nest to open the final objective and win the round. On the other side, Defenders will have to rely on melee attacks and Oryx’s Ramah Dash to stop their opponents and claim victory.

It all sounds very cool, and if you're wondering why now - well, that comes down to Rainbow Six Extraction's original September release being pushed back to next year. The Containment event also sees the arrival of new headgear, uniforms, and weapon skins for all Operators via time-limited customisation items going up for sale.
