I suggest for the best gaming experience, if you have not finished the game yet, stop looking at this solution and the trophy list and come back after you have finished your first playthrough.This trophy requires you to play consecutively form Chapter 10- Homeless right though until the end. Remember to set save to
on so you do not have to do it in one sitting.
*** Spoiler - click to reveal ***The six people that need to die are (in order)-
*Walter
*Jimmy
*Paul
*Norah
*Cole
*Ryan
Chapter 10- Homeless
The fire. Ignore Walter's cries for help and head upstairs. Follow Jimmy's cries for help and kick the door down to find him trapped press X to tell him to jump over to you and he'll say he can't. Ignore him and head out of the window.
Chapter 14- Navajo
At the end of the chapter you'll return to the ranch to find that Paul has been injured by the entities and he is taken to his room to rest. Just don't go to his bedroom to heal him.
Chapter 20- Norah Grey
After talking to Norah and taking her necklace off. Use Aiden to stop her heart and put her out of her missery
Chapter 24- Black Sun
In the section after putting the containment belts on, Cole will get knocked down by an entity. Do not turn around to help him. After this section you will be in an area with little visibility heading towards the Black Sun. When you reach Nathan you'll start talking to him when prompted chose "Blame" (triangle) and then "Cold" (square). Doing this will make him shoot you. After you have been shot do not choke Nathan using Aiden. Eventually Ryan will turn up to help you and Nathan will shoot Ryan too.
Now you have to reach the shut down switch.
I cannot confirm either way if you're able to unlock this trophy if you fail the series of QTEs after Ryan gets shot.
After deactivating the Black Sun you will have the choice of "Life" or "Beyond", choose Beyond to join everyone in the Infraworld.
This trophy will unlock after watching the credits.
