# GAMEINDEX — Project Void: Psychological Horror FPS Prototype

**Version:** 1.0 | **Generated:** 2026-05-21 | **Target UE:** 5.5–5.7
**Framework:** UE5 Modular Game Framework (135 systems)
**Game:** Project Void — Abandoned Asylum Psychological Horror

---

## Purpose

This document is the master index for the **"Project Void"** example game prototype. It defines:
1. The complete `Content/Game/` folder structure — every asset to create
2. Which framework system each game asset demonstrates
3. The full scene loading flow from boot to credits
4. Expansion notes for extending the prototype into a full game

**Rule:** All game content lives in `Content/Game/`. Never modify `Content/Framework/`. Game assets reference framework systems via interfaces, dispatchers, and Data Asset children.

│  Setting:    Abandoned Blackwood Asylum, 1920s          │
│  Player:     Dr. Eliza Vance — investigative journalist │
│  Premise:    You wake inside the asylum with no memory  │
│              of how you arrived. The building shifts     │
│              around you. Patients roam the halls.        │
│              Something older than the asylum             │
│              watches from the void between rooms.        │
│                                                         │
│  Tone:       Silent Hill meets Amnesia meets Outlast    │
│  Core Loop:  Explore → Find clues → Solve puzzles →     │
│              Evade threats → Piece together memory →    │
│              Unlock new areas → Reality shifts          │

- [ ] `Content/Game/` contains ALL game-specific content
- [ ] Game Blueprints are children of Framework Blueprints (never modify parent)
- [ ] Game Data Assets are instances of Framework Data Asset types
- [ ] Game references framework via interfaces and dispatchers (no hard refs)
- [ ] Project Settings point to Framework GI_GameFramework as Game Instance
- [ ] Game Maps reference GM_HorrorGameMode as GameMode override
