About This Game

Subject 404 is a psychological horror game where you awaken as a test subject inside an unknown facility.

You are not given a name. You are not given answers. You are only given instructions and a number.

A panel speaks to you. You are expected to obey.

Gameplay

The panel issues a continuous stream of commands that must be followed under time pressure.

Each command places you in a different situation:

The commands are fast, unpredictable, and intentionally disorienting. Hesitation is often fatal.

Failure Has Consequences

If you make a mistake, the Executioner arrives.

You don’t see its face. You only hear it approaching.

Death sends you back to the beginning.

Endless Rooms

Each room contains:

Complete the command correctly and the door opens, leading to the next room. Each chapter requires a set number of successful commands before reaching a Safe Zone.

Safe Zones and Anomalies

Safe Zones remove time pressure — but not unease.

Inside them, you may encounter:

Narrative Approach

The narrative unfolds naturally as you move, observe, and interact with the environment.

Visual Style & Atmosphere

The visual style is not nostalgic — it is designed to feel uncomfortable.

Subject 404 is a short but intense psychological horror experience about obedience, control, and the consequences of hesitation.
