Video description: The Zariman Ten Zero cries out into the endless darkness of space. In a post-New War Origin System, something lingers in this Void-wrecked vessel that the Tenno once called home. Return to where it all began, find the source of the Zariman's song and illuminate the mysteries that echo through its vacant corridors.
Angels of the Zariman is the highly-anticipated follow-up to The New War, featuring new enemies, three new Mission types, an electrifying new Warframe and so much more - all seamlessly connected by a brand-new social hub.
