The shadows are calling as Obsidian Moon, the upcoming noir detective simulator from Lost Cabinet Games, opens its case files to the public with a playable demo during Steam Detective Fest. Available now on PC via Steam, the demo gives players their first chance to investigate a murder, follow leads their own way, and decide how far they’re willing to go in pursuit of the truth.
A Gritty Noir Detective Experience Rooted in Choice
Set in a rain-soaked city choked by secrets and moral decay, Obsidian Moon is a text-based detective adventure inspired by classic 1930s noir fiction and psychological thrillers. Players step into the worn shoes of Carter, a once-respected homicide detective grappling with grief, alcoholism, and a crumbling sense of self.
Tasked with solving a series of interconnected murders, Carter must rely on logic, instinct, and intuition—while his own mental state steadily deteriorates. Every decision shapes the investigation, pushing players to confront not only the case at hand, but also the personal cost of uncovering the truth.
Investigate Your First Murder in the Obsidian Moon Demo
The Obsidian Moon demo, released as part of Steam Detective Fest, features the game’s first full murder investigation rather than a limited vertical slice. Players can interrogate suspects, analyze evidence, dig through records, or pursue more ethically questionable shortcuts, with the case dynamically adapting to each approach.
With more than 30 possible investigative paths, the demo emphasizes freedom and consequence, allowing players to experiment, fail, and discover new outcomes based on their choices.
According to Game Director Yannis Antonakakis, Steam Detective Fest was the ideal opportunity to showcase the game’s depth:
The demo is designed to let players truly live inside an investigation, encouraging experimentation and mistakes, even when the cost is high.
