Sleepless Night Studio

Sleepless Night Studio is a Chinese game development studio known for the multi-platform role-playing game currently titled Codename Bang Bang (代号砰砰), a female-oriented otome RPG that has also been presented under the working titles Under the Night and Reign of Nightfall. Designed for iOS, Android and PC, the game is set in the fictional kingdom of Milan, where players take on the role of the First Duke of Milan, a powerful and morally ambiguous mafia boss seeking to rebuild a fallen empire. It blends romance, strategy and political intrigue, offering a bold twist on the otome genre with turn-based combat, character collection and relationship-building mechanics wrapped in a stylish, noir-inspired aesthetic. A cast of charismatic male leads, each with distinct personalities and backstories, drives the narrative forward. The title supports both Chinese and English voiceovers, and its development team is composed of veterans of other popular female-targeted games.
