About Injection No.9 - Chapter 1 (The Prologue)

Injection No.9 - Chapter 1 (The Prologue) - about the game
Step into the role of a detective investigating an abandoned asylum, where reality warps amid creaking floorboards and echoing whispers. This psychological horror prologue delivers a slow-paced adventure through the men's wing, blending immersive exploration with environmental storytelling in decaying rooms filled with clues. Flickering lights and isolation heighten tension as you uncover the facility's grim past. Navigate narrow corridors using a multi-mode flashlight to spot hidden traces in UV or standard beams, while your smartphone links you to a dispatcher for photos and motion radar updates. AR glasses capture evidence with night vision backup, and a sanity system on your wristwatch tracks mental strain from the oppressive atmosphere. Fans of atmospheric indie simulation and action drawn to discovery-driven tension will find a complete, fully playable chapter here.

Injection No.9 - Prologue is the first chapter in a psychological horror series.

WARNING: This video game may potentially trigger seizures for people with photosensitive epilepsy. Player discretion is advised.

Important Note: This is the complete and fully playable first episode of a longer story-driven game series that will come. All gameplay systems and mechanics are fully implemented – this is not a demo or a limited preview.

Storyline

You are a detective haunted by shadows of the past.
An anonymous tip leads you to a long-abandoned asylum on the outskirts of the city. The building is crumbling, but something inside is very much alive. As you step inside, reality begins to twist. Doors vanish. Whispers echo from the walls. Your only link to the outside world is a dispatcher on the phone—someone who seems to know more than they should.

Environment

The story unfolds within the decaying walls of an abandoned asylum, long forgotten by time. In this episode, players will explore only the men's wing, located on the left side of the facility.

Creaking floorboards, rusted doors, and faint whispers from the past shape an eerie, oppressive atmosphere. Each room tells a piece of the asylum's dark history, blending psychological tension with environmental storytelling.

Expect narrow corridors, flickering lights, and a constant sense of unease as you uncover what really happened behind those locked doors
