You play as a Proxy, a guide who leads others safely through the Hollows, and the story unfolds across the city's rival factions. Combat is fast and real-time. You build a squad of up to three Agents, chain Basic and Special Attacks, and use dodges and parries to counter enemies before unleashing finishers on stunned foes. Between missions, the game adds a slower layer of city life, character stories and side events. Like HoYoverse's other titles, it runs as a live service, with major versions adding new characters, story chapters and limited-time events; Version 3.3, \"Journey to the Sky\", reached the App Store on October 20, 2026. New characters and equipment are obtained largely through a gacha system, and the game offers in-app purchases.
