Invisible Savior

Invisible Savior is an achievement/trophy in Metro: Last Light and Metro: Last Light Redux that can be obtained in the level "Facility".
==Overview==
This achievement is awarded for completing "Facility" without being caught, raising any alarms or killing anyone. If you fail in any way, you have to restart the level from the beginning (restarting is not necessary in Redux, reloading the last checkpoint is enough).
