# ⚙️ Inside The System: Anomalies — Horror Edition
Welcome to a broken simulation. Inside The System is an immersive psychological and environmental survival horror modpack built on NeoForge (1.21.1). The code is corrupted, the environment is unstable, and you are not alone.
👁️ Features & Core Concept
- Digital Corruption: Experience a world that feels like a glitching, decaying reality.
- Terifying Visuals: Powered by Insanity Shader and EnhancedVisuals for unmatched atmosphere, blood splatters, and screen distortions.
- Realistic Soundscapes: Immersive spatial audio with Sound Physics Remastered — every footstep and echo matters.
- Ultimate Optimization: Smooth gameplay and high FPS thanks to Sodium and Iris Shaders.
🛠️ Modlist Highlight
This modpack carefully balances immersion, performance, and terror. Key modifications include:
- Inside the system — The core mechanical and thematic foundation.
- Insanity Shader — Dark, foggy, and atmospheric world rendering.
- EnhancedVisuals — Heartbeats, blur, and damage indicators.
- Sound Physics Remastered — Realistic sound attenuation and echoes.
- Sodium & Iris — Industry-standard performance optimizations.
