In the trailer below, Osa uses her shield to block a window. It doesn’t cover the full thing, leaving a small gap in the top that people could shoot through. The shield itself is bullet proof, though it does look like it might be breakable after a lot of bullets have been thrown at it. Interestingly, Osa is an attacker. I would’ve thought an ability like this would’ve been part of a defender’s kit, but I suppose it makes sense if she can also wander around with the shield out to protect her squad. Perhaps the best offense truly is a good defense. The developers have also released a little bit of background info on Osa in the form of a letter from one Siege character to another. It says: “The device she’s bringing 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.” Mira is a defense operator who can make little windows in reinforced walls. Those have to be meleed to be destroyed, so perhaps Osa’s shields will be similar? Fortunately, we don’t have to wait too long to find out. The full reveal for Osa and the Crystal Guard update is set for Monday the 16th of August at 3pm BST (7am PT) over on Twitch.
