Pathologic 2

For those that would actually like to play the game, this achievement is actually story related and not missable. You'll get it on Day 9 after watching a cutscene of the commander arriving. I can't remember when exactly it happens, I believe it's just literally when the day starts at 7:30 am. Regardless, you won't miss it.

All the info I got is from QuentinCle95 and their great walkthrough here; https://psnprofiles.com/guide/10147-pathologic-2-trophy-guid...

All credit goes to them, would definitely recommend using it if you want a concise roadmap of achievement related activities that need to be done day to day.
