Obsidian Moon promises a psychological descent into a series of murders that tie into a growing, otherworldly conspiracy hidden beneath the city’s surface.

As Carter, a once-respected homicide detective haunted by grief and failure, you’ll be asked to solve a string of interconnected cases through logic, instinct, and the steady collapse of your own sanity.

Armed with vintage forensics, gritty intuition, and limited time, you’ll follow leads, interrogate suspects, and make costly choices that may bring you closer to the truth, or break you entirely.

Inspired by Lovecraftian horror, 1930s noir, and Mediterranean chthonic mythologies, Obsidian Moon melds storytelling with genre-bending mechanics that echo titles like Stacklands, Papers, Please, and Cultist Simulator. Every case is a story. Every choice leaves a scar.

"We wanted to build a detective game that gives players true investigative freedom, not just to solve the case, but to lose themselves in the process", said Game Director, Yannis Antonakakis. "The entire design is built around one question: what if all the clues were laid out in front of you, and the only thing standing between order and chaos was your mind?"

Key Features:

• 10 sinister murder cases that converge into a wider conspiracy, bound by blood, shadow, and secrets.
• Player-driven investigation – interrogate witnesses, run forensic reports, dig into criminal records… or use your magnum to extract a confession (seriously don't do this)
• A noir descent into madness – choose between stability or spiraling; every lead costs you time, money… and maybe your mind.
• Multiple modes – including a Hardcore permadeath mode and immersive Noir black-and-white filter.
• Three narrative lenses – track the crumbling psyche of Carter, the reactions of Chief O’Hara, and the naive wonder of your partner, “The Kid.”

 Obsidian Moon is in development for PC (Steam).
