The latest Rainbow Six Siege season, Operation Crystal Guard, hits test servers tomorrow, and it’s packed with new content and gameplay tweaks. The headline features of Ubisoft Montreal’s latest update include new attacker Osa, who can deploy a handy see-through shield in doorways and windows, and a trio of map reworks for the Bank, Coastline, and Clubhouse. You can check out a quick character teaser for Osa, below.

　　And here’s a more in-depth gameplay overview of Osa and the newly-reworked maps.

　　Here’s the rundown on the new Operation Crystal Guard content:

　　New Attacker: Osa

　　Anja “Osa” Janković, trained in electromechanics, military engineering and robotics genius. Recruited into Nighthaven right out of university, founded their R&D department called “Quantum Concepts & Robotics,” trained in field operations by Kali herself. Boss lady doesn’t mention her much, so I got Ace to talk. According to him, Kali and Osa tell each other everything. Kali is very protective of her, and not just because she’s her “golden goose”. Best friends, business partners, however you want to describe it. There’s a lot there that Harry could get at.

　　The device she’s bringing to the battle is sure to play on lines of fire. A clear shield with mechanical claws that digs itself into surfaces and frames? Its defensive capabilities designed for offensive missions might make Mira jealous that she didn’t think of that first. Still, I’m not seeing anything yet that suggests Nighthaven is trouble.

　　Unique Abilities and Playstyle – The transparent and bulletproof Talon-8 Shield can be carried by Osa or deployed on floors or window frames, giving her a protective line of sight while she formulates a strategy.Primary Weapon – 556xi, PDW9Secondar Weapon – PDDGadgets – Claymore, Smoke GrenadeMap Reworks
