Big thanks for explaining some things to discord server of this game.
By the way, SPOILER ALERT!!!
SPOILER ALERT
I’ve got it after watching at the cave painting in Amanda’s house. Maybe you got it other way.
Truth Seeker
Talk with all people in the neigborhood.
Broken Bonds
There will be one guy, named Brian as I remember, living in poor house near us and who will kick us away from his property. You can interact with laptop in his bedroom, after this you’ll get the achievement.
Mercy or Wrath
Choose Farmer destiny (kill or let him go).
Destiny Sealed
End of the game. Now your messages, nickname and last choices are saved, though you can replay it, but it won’t affect these aspects.
Final Choice
Same as previous one.
Ghost of the past
This is interesting one. You need to start the game, until there will be radio under you mom’s portrait on the first floor. Then you can see ghost (old man looking similar to you) in the window, on the second floor bedroom in the Amanda’s house. Then you need to activate the easter egg in corn fields (there will be a white shape of corpse here, step on it), after what go to ghost and talk with him. He will tell more plot to you, and achievement is yours.
Flush the Darkness
Flush every toilet in the neigborhood. From the “difficult to find” are one in the shop and on the backyard of police officer with cool leather coat house, near house for rent. I dare you to complete this achievement, it will definitely leave you in good mood 😉
Ray of Hope
This is strange/buggy one, as I understood you need to try to call for help (instead of trying to help end her pain lol).
