About this game
Mary awakens in a high-contrast world with no memory, trapped within a series of isolated and deadly scenarios. Trials of Mary is a story-driven, cinematic survival horror experience where your intelligence is your greatest weapon. Within a modernized nightmare loop, you must confront the darkest rules of classic horror cinema.
This journey, consisting of 4 main chapters each with its own unique atmosphere, offers 5–6 hours of intense gameplay. Stripped of unnecessary details, this experience allows you to directly encounter the most iconic subgenres of horror cinema.
Core Gameplay Features:
Intelligence and Strategy: Even if you are not a fighter, you can use environmental objects to survive and defend yourself when necessary.
Real-Time Interaction: No time wasted in menus; to solve complex puzzles, you must physically pick up, rotate, and examine objects in the 3D world.
Dynamic Escape and Defense: Use the environment to evade your pursuers. Each chapter presents unique enemy behaviors that force you to adapt your strategy.
Minimalist Interface: Focus entirely on the atmosphere with a “living” camera perspective that reacts to Mary’s fear, without cluttering the screen with UI elements. Can you complete this descent before the darkness fully consumes you?
The trial begins now.
