Roadshow Entertainment has launched an Underbelly: Razor Facebook game which challenges users to survive a night in gritty 1920s Darlinghurst.
Created by digital agency Profero, the "Razor Wars" game takes the form of a choose-your-own-adventure story, with each choice keeping the user guessing as to whether they have made the right decision.
Fans can share how they fared on their Facebook wall and challenge their friends.
