+# Cutscene System Implementation Roadmap
+
+## Overview
+This document outlines a step-by-step roadmap for implementing the cutscene system in Godot 4.3, based on the architectural designs created.
+
+## Phase 1: Foundation
+
+### 1.1 Base Action Class
+- Create `Action.gd` base class
+- Implement state management (PENDING, RUNNING, COMPLETED)
+- Add core signals (started, completed, failed)
+- Implement basic methods (start, update, is_completed, stop)
+
+### 1.2 CutsceneManager Core
+- Create `CutsceneManager.gd`
+- Implement sequential action queue
+- Add action addition methods
+- Create basic state management (IDLE, RUNNING)
+
+## Phase 2: Core Action Types
+
+### 2.1 WaitAction
+- Simplest action to implement and test
+- Validates the basic action system
+- Tests completion signaling
+
+### 2.2 MoveAction
+- Implement character movement logic
+- Add position calculation and frame-based updates
+- Test with different speeds and distances
+
+### 2.3 TurnAction
+- Implement character rotation logic
+- Handle both position and node targets
+- Test smooth rotation animations
+
+## Phase 3: Advanced Features
+
+### 3.1 Parallel Execution System
+- Implement parallel action group management
+- Add completion tracking for parallel actions
+- Test with multiple simultaneous actions
+
+### 3.2 DialogueAction
+- Implement basic dialogue display
+- Add duration-based completion
+- Test with different text lengths
+
+### 3.3 AnimationAction
+- Implement animation playback
+- Handle AnimationPlayer integration
+- Test with looping and non-looping animations
+
+## Phase 4: Completion and Callback System
+
+### 4.1 Signal Integration
+- Connect action signals to CutsceneManager
+- Implement action completion handling
+- Add error handling and failure recovery
+
+### 4.2 Callback System
+- Implement action-level callbacks
+- Add cutscene-level callbacks
+- Test callback chaining
+
+### 4.3 State Management
+- Implement full state transitions
+- Add pause/resume functionality
+- Test state persistence
+
+## Phase 5: Testing and Examples
+
+### 5.1 Basic Cutscene Example
+- Create simple sequential cutscene
+- Test all core action types
+- Validate completion flow
+
+### 5.2 Complex Cutscene Example
+- Implement the requirement example:
+  - Character1 moves to 234, 591
+  - Character2 moves to 912, 235 (simultaneously)
+  - Character2 turns to Character1
+  - Character2 says dialogue
+  - Character1 plays shocked animation
+- Test parallel execution
+- Validate timing and synchronization
+
+### 5.3 Edge Case Testing
+- Test empty action queues
+- Test failed actions
+- Test rapid state changes
+- Test memory management
+
+## Phase 6: Extensibility Features
+
+### 6.1 Custom Action Example
+- Create a custom action type
+- Demonstrate extension process
+- Validate compatibility with core system
+
+### 6.2 Plugin Architecture
+- Implement basic plugin system
+- Create example plugin
+- Test plugin integration
+
+### 6.3 Performance Optimization
+- Implement object pooling
+- Add performance monitoring
+- Optimize update loops
+
+## Implementation Order

+```
+
+## Testing Strategy
+
+### Unit Tests
+- Each action type tested independently
+- CutsceneManager state transitions
+- Signal emission and connection
+- Error handling paths
+
+### Integration Tests
+- Sequential action execution
+- Parallel action execution
+- Mixed sequential/parallel sequences
+- Callback chaining
+
+### Performance Tests
+- Large action queues
+- Multiple simultaneous cutscenes
+- Memory allocation/garbage collection
+- Frame rate impact
