# 12 — Settings, Accessibility, Haptics & Platform Systems (Systems 104-105, 148)
| # | System | Asset Type | Role |
|---|--------|-----------|------|
| 104 | `BPC_AccessibilitySettings` | Component | Accessibility; subtitles, colorblind, controller remap |
| 105 | `SS_SettingsSystem` | Subsystem | Settings subsystem; persistent settings, apply, reset |
| 148 | `BPC_HapticsController` | Component | Haptics controller; GameplayTag-driven force feedback, DualSense triggers, heartbeat pulse |
**104 BPC_AccessibilitySettings:** Manages accessibility features: subtitle toggle/size, colorblind mode selection (protanopia/deuteranopia/tritanopia), controller remapping, difficulty presets, hold-to-confirm toggle, camera shake reduction. Settings persisted via `SS_SettingsSystem`.
**105 SS_SettingsSystem:** GameInstanceSubsystem for all persistent settings. Loads defaults on init, saves on change, supports reset-to-default. Settings categories: Audio, Video, Controls, Gameplay, Accessibility. Coordinates with `SS_AudioManager` for volume, `SS_EnhancedInputManager` for key rebinding.
**148 BPC_HapticsController:** ActorComponent attached to the Player Controller. Central abstraction for all controller vibration and force feedback. Systems trigger haptics by GameplayTag (e.g., `Haptic.Damage.Heavy`) — never calling raw UE5 `Play Force Feedback` nodes. Handles platform detection (Xbox rumble, PS5 DualSense adaptive triggers, PC generic gamepad), respects accessibility toggle, manages effect priority/conflict resolution, and drives the continuous heartbeat pulse from `BPC_StateManager.GetCurrentHeartRate()`. Uses `DA_HapticProfile` Data Assets for all effect definitions.
