Everyone Lives - Chose Beyond
It's important to select "Beyond" at the conclusion of the video game, leaving everybody live:
1. Walter & Jimmy - Rescue the first on the first floor of the structure burning down in chapter "Homeless", recovery the second one upon the second floor.
2. Paul - Save him healing his injuries with Aiden, at the conclusion of the chapter Navajo.
3. Save your mom Norah: you'll be offered the possiblity to stop the woman's heart with Aiden, simply just don't do it and walk away.
4. Ryan & Cole - The first will magically seem risk-free after the death of Dawking (simply tell him to Move twice), the second will need to be cured on the same chapter by simply Aiden.
Everyone Dies - Chose Beyond
In order to obtain this final you must do the exact opposite of ending 1, and then choose Beyond.
Inside the chapter "Black Sun", at a certain moment entities along with ghosts will definitely try to block Jodie. You will have to solve several QTE (Quick Time Events), simply just do not do it and Jodie will die.
Live with Jay
Opt to spend your life along with Jay at the conclusion, after you have selected Life. Eventually Aiden will come back.
Live with Zoey
Decide to spend your lifetime together with the just born Zoey, after having selected Life.
Choose Life at the conclusion of the game, and so spend your leftover existence by yourself. You make the others live or die.
Live with Ryan
Spend your life together with Ryan, after having chosen Life. Sooner or later inside the last scene Aiden will certainly come back.
