About This Game

Uncover the Truth

The Shadows of the Past Demand an Investigator

Shadow Mansion is a narrative-driven, first-person horror and investigation game that prioritizes psychological dread and active deduction over simple jump scares. You don’t merely survive the mansion you must uncover the dark truth it has buried for decades.

Your journey begins with a mysterious letter that summons you to an abandoned family estate. To make it out alive, you must take on the role of a supernatural investigator, following a trail of fragmented clues to piece together a tragic family secret that was never meant to be revealed.

Key Investigative Features

🔍 Deep Environmental Investigation
Search every corner of the mansion to uncover hidden notes, listen to long-forgotten tapes, and examine subtle environmental clues. Progress depends not on collecting items alone, but on understanding what they truly mean.

🧩 Deductive Puzzle Solving
Progression is locked behind layered mysteries. You must gather scattered information fuses, ritual artifacts, cryptic keys and connect the dots to access the mansion’s most forbidden areas.

📓 A True Detective Mindset
Track your discoveries and reconstruct the dark pacts made by your family. You are not a passive observer you are the central investigator of a complex, multi-layered case.

🗝️ Stealth & Observation-Based Survival
You are not alone. A demonic presence and its followers stalk the mansion. Survival depends on careful observation, pattern recognition, and understanding the hidden logic behind the hauntings.

🕯️ Relentless Atmospheric Tension
Navigate pitch-dark corridors, restore failing systems, and manage your limited tools. Every flickering light carries meaning, and every silence may be a warning.
