Lost Signal is a lightweight psychological horror shader designed to create a tense, immersive atmosphere without requiring a high-end PC.

 

Instead of focusing on realism, Lost Signal recreates the unsettling feeling of exploring the unknown through darkness, subtle analog-inspired visuals, and atmospheric post-processing.

 

Features

 

- 🌑 Dark, immersive nights

- 🔦 Dynamic flashlight effect for torches and lanterns

- 📼 Analog-inspired grain and screen effects

- 🌧️ Rain blur

- ❤️ Fear Pulse

- 😨 Panic effects

- ⚙️ Customizable settings and intensity profiles

- 📱 Optimized for low-end devices

Lost Signal is still under active development. Features, visuals, and performance will continue to improve with every update. Feedback, bug reports, and suggestions are greatly appreciated and help shape future versions.
