If you prefer to watch a video instead of reading the guide, feel free to do so. There is a playlist that covers every trophy on my YouTube channel. If you'd like and subscribe or even become a member, it would mean a lot to this channel!

During our first playthrough we only make Head decisions, keep everyone alive and collect as many secrets & pictures as possible.
For our second full playthrough of the story we need to ensure that only make Heart decisions and let everybody die at the ruined house.
To mop up the remaining trophies you we can go back to our Head-only playthrough and restart from the chapter "Confrontation". Create a new save from there in case something goes wrong.
