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

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

Gameplay

Immersive Exploration – Navigate the dark, decaying men’s wing of an abandoned asylum in a slow-paced, atmospheric experience focused on tension and discovery.
Multi-Mode Flashlight – Use a standard beam to light your path, or switch to UV mode to reveal hidden messages, clues, and paranormal traces.
Interactive Smartphone – Stay in constant contact with your dispatcher, send photos, receive updates, and access critical apps like the motion radar to detect nearby movement.
AR Glasses with Night Vision – Take photos of key evidence and use night vision as a backup when your flashlight battery dies.
Sanity System – Monitor your mental state through a wristwatch as the psychological weight of your surroundings begins to affect your perception.
Environmental Storytelling – Every room tells a story; uncover what happened through visual cues, documents, and interactive objects.
High-Tension Atmosphere – A focus on sound design, lighting, and isolation creates a deeply unsettling experience without relying on constant jump scares.

Challenging, but worth it! Game doesn't hold you hand so every completed step feels earned. Visually, it’s impressive.. good graphics and atmosphere, especially for a new developer. There were a few issues with opening doors, but hopefully it will be adjusted in a patch. Looking forward to the next chapter. Also, wanted to thank the Developers for stopping in during our first play through live. :) Cheesyobject

Honestly this game is very spooky, I was given the honor and approached by the developer to play this game on stream before release. I would definitely recommend this game if anyone is interested in spooky asylum games. Give it a try!

This game is the first game made by Ragdoll Games! 2 Developer team and honestly a great experience especially for a first game! A good creepy eerie experience with some jumpscares and scary atmosphere. Only feedback I have is to increase the mouse sensitivity when opening doors and with the power grid puzzle to provide a confirmation when you complete it correctly. Otherwise loved it!!

I really enjoyed this horror game! The atmosphere was incredibly immersive, the story kept me hooked from start to finish, and the jumpscares were genuinely terrifying. I’m already looking forward to Chapter 2 ,can’t wait to see what happens next!

Not recommended Jun 5, 2025

Game play clunky, almost impossible to open doors and dresser drawers. This is nothing more than a cheap demo, I can't believe i paid 15 bucks for this...don't buy this game
