Project BangBang (代号砰砰, or Code Name: Bang Bang) is an upcoming narrative-driven Gacha RPG developed by Sleepless Night Studio, targeting a female audience (joseimuke/otome).
The game is set in a fictional noir-inspired city called Milan, it features a female protagonist (exclusively, no male options,) who is a ruthless mafia boss and First Duke, navigating a morally gray world of power struggles, betrayal, and romance. The game blends mafia themes, dark storytelling, and high-quality fanservice, with a focus on “husbando” (male) characters as love interests or allies.
While specific mechanics remain undisclosed, it’s expected to combine RPG elements with action-based combat, potentially similar to Love and Deepspace. Players rebuild a fallen mafia empire, manipulate factions, and engage in intense relationships (romantic or antagonistic) with a cast of dangerous, attractive male characters. The art style is reminiscent of Reverse: 1999, with English (regional) and Chinese voiceovers.
Project BangBang is releasing on to iOS, Android, and PC, it is currently in beta testing in China with pre-registration currently closed. At present, no global release date is confirmed.
