Yes, I know that there is a different guide like this already posted, but I feel like OP have been inspired by my Metro 2033 Redux guide. Also sorry for any spelling / grammar errors you might find, english is not my native language.
If I’ve missed or forgot something, please let me know in the comments below. Note that this is not game walkthrough per se, it is a guide / walkthrough on all collectibles and achievements. How to get 100% in Metro: Last Light Redux in as less time as possible.
