Level Design — All 11 Maps

Game: Project Void | Build Phases: 2 (splash/menu/test) + 21 (full levels) Framework Systems: 05_GM_CoreGameMode, 19_BP_DoorActor, 37_BP_Checkpoint, 67_BP_NarrativeTriggerVolume, 92_BPC_ProceduralEncounter, 93_BPC_AdaptiveEnvironmentDirector, 133_BP_RoomAudioZone

---

Purpose

Defines the layout, objectives, placed assets, and atmosphere for every .umap level in the game. Each level builds on the previous, introducing new systems incrementally.

L1 — L_SplashScreen

Duration: ~8 seconds (skippable) | Framework: 114_WBP_SplashScreen

Setup:
  1. New Level → Empty Level
  2. Add PostProcessVolume:
     - Set to Unbound: true
     - Film → Saturation: 0.9
     - Color Grading → cool desaturated look
  3. Add WBP_SplashHorror widget to viewport on BeginPlay
  4. Level Blueprint: OnBeginPlay → PlaySplashSequence
  5. OnSequenceComplete: OpenLevel("L_MainMenu")

Placed Assets:
  - (None — this is a UI-only level with no world geometry)
  - Optional: add a CameraActor + black VoidPlane for background

Audio:
  - SS_AudioManager.PlayMusic("splash_ambient", MS_MusicBus)

Enemies:
  └─ BP_Enemy_Shade × 1 (persistent pursuer)
       ├─ Teleports between dark corners
       ├─ Flashlight delays its approach (slows to 50% speed)

       └─ If caught → instant death → Void Space

Stress Mechanics:
  ├─ Player stress rises constantly (+2/sec) in total darkness
  ├─ Using flashlight: stress rise slows to +0.5/sec
  ├─ Battery depletes: stress rise doubles
  ├─ At Breaking (75+): screen distortion, false enemy sounds
  └─ At Catatonic (100): player collapses, Shade appears

Audio:
  ├─ BP_RoomAudioZone_Basement (heavy reverb, dripping water, distant screams)
  ├─ SS_AudioManager.SetFloatParameter("HeartRate", player heart rate)
  └─ 4 scare sting cues placed at specific trigger volumes

Atmosphere:
  ├─ NO PostProcess volume "auto-exposure" — pure darkness without flashlight
  ├─ BP_LightEvent_Flicker × 6 (throughout basement — random flickers)
  └─ DA_Atmosphere_Basement_Dark → maximum horror preset

  ├─ BP_Enemy_Shade × 1 (pursues in void — cannot be killed)
  └─ BP_Checkpoint_VoidThreshold (one-time checkpoint)

Shrine Solution:
  ├─ Shrine 1: Player's reflection shows a key moment from earlier

Level Creation Checklist (per level)

For each level, ensure:

• World Settings → GameMode Override = GM_HorrorGameMode
• PlayerStart actor placed (at least one)
• Lighting: DirectionalLight + SkyLight + PostProcessVolume (horror grade)
• Audio: At least one BP_RoomAudioZone covering the playable area
• Navigation Mesh: Build → Build Paths (NavMeshBoundsVolume covering all walkable areas)
• Collision: All walls/floors have collision; doors have interaction collision
• Loading: Level name registered in GM_HorrorGameMode.HorrorLevelNames map
• Save Support: All I_Persistable actors present (doors, pickups, enemies)
• Checkpoint: At least one BP_Checkpoint placed
• Level Blueprint → OnBeginPlay:
  • Set chapter tag on GS_HorrorGameState
  • Load atmosphere profile via BPC_AtmosphereStateController
  • Start music via SS_AudioManager
  • Fire BPC_NarrativeStateSystem.OnChapterStart

Notes for Expansion

• Each level should have a paper map (diegetic) that player can find — shows layout
• Consider streaming sub-levels for large areas (basement corridors) to manage memory
• Add environmental storytelling: blood trails, scratch marks, patient drawings on walls
• The void space could be procedurally generated using BPC_AdaptiveEnvironmentDirector
• Add New Game+ variations: enemy placements shift, doors start locked differently
• Test sandbox should include a stress/sanity debug overlay (F1 toggle)
• Each level exit door should glow faintly (diegetic guidance, not quest marker)
• Use data layers for adaptive environment: rooms that shift should be in a separate data layer
