Atelier Online is an anime-style tactics role-playing game with a side view. Characters such as Rorona and Marie from the previous Atelier series join the game to experience a never-before-seen story. Elements and monsters on the island will appear depending on the weather and day. Players can also explore the island with up to 3 friends in online co-op multiplayer mode. Players can try out different equipment on their characters, such as clothing, weapons, and accessories, to improve stats, change appearance, and gain new skills.
