How to unlock the Invisible Soldier achievement in Metro: Last Light Redux - Definitive Guide
Explaining the path through the level via text would be extremely confusing, so instead I recommend watching this video:
However on SURVIVAL this will not work.. it may work on your original campaign run if you wait around in the 3rd an 4th sections an knock out the guards but im not sure..
I used chapter select after a Survival run an after completing the way your video showed with the use of reloaded checkpoints it did not work
it also did not work after completing without the use of reloaded checkpoints but i did knock out enemies.. that may have voided?? or you may not be aloud to reload the chapter?? not sure?? you may want to test or add into guide???
As the third “invisible” achievement, you should feel comfortable enough with the stealth gameplay mechanics at this point in the game. This level is much more difficult to navigate given the amount of enemies within the compound. Try to keep an eye on Artyom's watch and stick to the shadows. You'll definitely want to utilize the video below since this level is by far the hardest of the three invisible achievements.

An alarm is considered if the enemies turn on the siren.
