Pathologic 2

Spoilers for Day 10-11

You have to of spoken with Aglaya beforehand to earn this. Past 20:00 on Day 10, you'll get an objective to speak with Aglaya (the Inquisitor) at the Cathedral. She'll tell you she is going to be killed. Choose the dialogue options to agree to flee with her. When Day 11 comes, you can go to the station and ride with her out of the town. The train car stops and she is still killed. Follow the train tracks back to town and the achievement will pop.

There's a shorter way to pop these on the PC, and doesn't involve typing. Credit to RAILBAIT for the idea, but no extra steps are needed.

Yes, you need the PC version.

Press ctrl+shift+F4 at the main menu.
On the left, click on Inspector.
Click on Services (with a number after it)
Click on Element 0 (AchievementService)
Click the BIG Unlock All button in the middle.

Sir back and profit. It should take roughly... 10 seconds to get to the button. The popping will take considerably longer.
