- 9To unlock 'The Liberation' Trophy/Achievement and the File 'The End (7/8) - The History Between Edward and Luna': Choose to 'Turn off the equipment'. Interact with the life support device.
- 10To unlock 'The Benevolence' Trophy/Achievement: Choose to 'Leave the equipment on'. No further interaction is needed for this choice, but you will miss a File.
