How to Make a Horror Game in UE5
Complete step-by-step guide from the developers of Night At The Mall. Learn lighting, sound, and psychological horror mechanics.
Why Unreal Engine 5 for Horror?
Unreal Engine 5 revolutionizes horror game development with Lumen (dynamic global illumination) and Nanite (virtualized geometry). These tools let indie developers create AAA-quality atmospheres without massive teams.
We built Night At The Mall entirely in UE5, and this guide shares our battle-tested techniques.
Project Setup
Initial Configuration
Template Selection
Start with "First Person" or "Third Person" template. We used First Person for Night At The Mall's immersive POV.
Enable Lumen & Nanite
- • Project Settings → Engine → Rendering → Enable Lumen
- • This gives you real-time global illumination (crucial for horror lighting)
- • Enable Nanite on static meshes for high-detail environments
Performance Optimization
Set target platform settings early. For cross-platform (PC + mobile), create separate builds with adjusted quality settings.
Master Horror Lighting
Lighting is 80% of Horror Atmosphere
Dynamic Shadows
- • Use Spot Lights with low intensity (0.5-2.0)
- • Enable "Cast Dynamic Shadows"
- • Add flicker animation for broken lights
- • Create long, stretching shadows in corridors
Lumen Settings
- • Lower "Lumen Scene Lighting Update Speed" for eerie lag
- • Increase "Final Gather Quality" for realistic bounce light
- • Use colored lights (red emergency, blue moonlight)
- • Add fog/volumetric lighting in dark areas
Pro Tip from Night At The Mall
We layer 3 light types: ambient (very low), practical lights (visible sources like exit signs), and accent lights (hidden spotlights to guide player attention). This creates natural-looking but controlled horror lighting.
Atmospheric Sound Design
Horror Games Are 50% Audio
Ambient Audio Layers
- • Layer 1: Low-frequency drone (20-80Hz) for subconscious unease
- • Layer 2: Environmental ambience (wind, distant creaks, HVAC hums)
- • Layer 3: Occasional random sounds (footsteps, doors, whispers)
- • Use UE5's "Ambient Sound" actor with attenuation settings
3D Audio Implementation
- • Enable "Spatialization" on all sound cues
- • Set attenuation distances (Inner: 300, Outer: 3000)
- • Add reverb volumes in enclosed spaces (malls, hallways)
- • Use "Occlusion" so sounds muffle through walls
Sound Design Tip
Record your own footsteps on different surfaces (tile, carpet, metal). Unique sounds make your horror game feel professional. We recorded 40+ hours of mall ambience for Night At The Mall.
Psychological Horror Mechanics
Player Vulnerability
- • Limited visibility (flashlight with battery drain)
- • Slow movement speed in dark areas
- • No combat—pure evasion and hiding
- • Sanity/fear meter that affects gameplay
Environmental Storytelling
- • Notes, diaries, and audio logs
- • Visual clues in environment (bloodstains, signs of struggle)
- • Dynamic events (doors slamming, lights flickering)
- • Contextual jumpscares (not cheap)
Pacing Blueprint
Horror games need rhythm—tension, release, escalation:
- Introduction: Safe area, teach mechanics (5-10 min)
- First Scare: Establish threat without showing it fully
- Breathing Room: Puzzle section or safe room
- Escalation: Increase frequency and intensity of scares
- Climax: Direct confrontation or escape sequence
Optimize for Performance
Horror Games Need Smooth Performance
Stuttering breaks immersion. Target 60fps minimum on PC, 30fps on mobile.
Level Streaming
Break large maps into smaller sublevel chunks. Load/unload based on player position.
LOD (Level of Detail)
Use Nanite for hero assets, traditional LODs for background objects. Reduce polycount on distant meshes.
Light Baking
For static lights, use baked lighting. Reserve dynamic lights for key horror moments.
