# Psychological Horror - Horror Template | Summer Engine

## About this template

Picture a game where the level geometry changes when the player is not looking, where NPCs repeat dialogue with slight variations that feel wrong, where a door the player walked through three times suddenly leads somewhere different. Psychological horror does not rely on monsters. It relies on destabilizing the player's model of the world.

Summer Engine helps you build unreliable environments through conversation. Describe the kind of confusion you want to create, the narrative you want to fracture, the moment you want players to realize they cannot trust what they have seen. The AI helps construct systems that make reality feel slippery.

The best psychological horror games work because they establish rules and then systematically break them in ways that feel personal. The game appears to know things about the player it should not. That feeling of being watched by the fiction itself is what you are here to create.

## Who it's for

* Narrative designers who want to use game systems as horror tools rather than just atmosphere.
* Developers inspired by PT, Hellblade, or Disco Elysium who want to explore unreliable reality mechanics.
* Writers building a horror game where the story is inseparable from the mechanical experience.
* Teams willing to prototype unconventional ideas that do not fit standard horror genre templates.

## Highlights

* ### Narrative Horror Demo  
Build a 30-minute experience where environmental changes and repeating loops tell a fragmented story. Strong festival submission format.
* ### Unreliable Space Prototype  
Develop a single environment that shifts based on player progress, testing how subtle environmental manipulation creates dread before scaling.
* ### Character-Study Horror  
Build a game focused on a protagonist's deteriorating mental state, using audio hallucinations and visual distortions as mechanics, not decoration.

## Highlights

### Unreliable environment

Rooms change between visits. Objects move. Familiar spaces become unfamiliar. The game erodes the player's confidence in their own memory.

### Fractured narrative

Story told through contradictory fragments, repeated loops with variations, and environmental details that accumulate into an unsettling picture.

### Perception distortion

Visual and audio cues that may or may not be real. Players learn to question what they see and hear rather than trust it.

### Protagonist interiority

The player character's internal state manifests in the world. Their fear, guilt, or grief shapes what the player experiences.

## Features

* ### Dynamic environment manipulation  
Systems that alter level geometry, object placement, and lighting states based on player progress or triggers without visible loading screens.
* ### Audio hallucination system  
Directional audio events that lead nowhere, voices that comment on player actions, and ambiance that shifts in pitch and timbre as stress increases.
* ### Loop and echo mechanics  
Narrative structures where players revisit locations that have subtly changed, reinforcing the feeling that time or memory is unreliable.
* ### Sanity effect system  
Visual and mechanical distortions that increase with time spent in hostile spaces: screen warping, phantom sounds, HUD degradation.

## Genre fit

* Horror
* Psychological
* Narrative
* Walking Sim
* Desktop
* Console
