The interactive graph below visualizes achievement relationships. Click nodes to see prerequisites and unlock requirements. Use zoom and pan controls to navigate.
Plan Your Saves
Create manual saves before critical decision points (especially the Tama choice) to explore multiple paths without full replays. Check our Save Point Optimizer for optimal save locations.
Unlock Strategy
To unlock all achievements, you need at least 2 playthroughs due to mutually exclusive choices.
Achievement Dependency Graph
This directed acyclic graph (DAG) shows the relationships between achievements. Arrows indicate prerequisites - you must unlock the source achievement before the target becomes available.
Optimization Tips
Save Before Critical Decisions
Always create a manual save before major choice points, especially before the Tama decision. This allows you to explore different paths without replaying the entire game.
Thorough Investigation is Key
To achieve the better endings, take time to explore every location carefully. Read all notes, examine all objects, and exhaust all dialogue options.
Mercy Leads to Better Outcomes
In general, showing mercy and making compassionate choices leads to better endings. The kill Tama achievement exists for completion, but sparing him is crucial for the good endings.
Track Your Progress
Keep notes about which achievements you have unlocked to plan your subsequent playthroughs efficiently and avoid unnecessary repetition.
