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!
The most important thing for our first playthrough is that we only pick decisions indicated by a brain. However, if both decisions are heart decisions you can pick whichever you prefer. Those don't void the trophy.
A lot of the remaining trophies can be earned by slightly changing some decisions we made in our head-only playthrough.
To gather the remaining trophies it's recommended to start a new playthrough beginning at "The Briefing".
