Oni is a 2001 action game developed by Bungie West and published by Gathering of Developers.
Set in the year 2032, Oni is the story of Konoko, an elite agent of the Tech Crimes Task Force who is on a quest to infiltrate and destroy a ruthless crime syndicate. The game puts the player in a world that can be imagined as a blend of action thrillers, such as La Femme Nikita, and classic anime, such as Ghost in the Shell. As the game progresses, Konoko wrestles with the terrible secrets of the underworld, confronts the frailty of her own identity, and discovers that she can trust no one. Experience full contact action in a futuristic anime-inspired 3-D world. Empty your clip into your opponents and then take out the survivors with flying kicks and neck-snapping throws. With its revolutionary engine, Oni will change the way you look at third-person action games.
Oni is abandonware and no longer sold or supported by its publishers. Files are archived here for these platforms:
