If you managed to play through the terrifying and twist-filled story to the end, you'll know that the choices you made and the actions you took led you down a unique path. In fact, there are a total of 22 Butterfly Effect events that affect the fates of the game's eight protagonists, resulting in hundreds of possible combinations of who lives and who dies during that fateful night in Blackwood.
Many of Until Dawn's trophies are designed with this in mind: to reward multiple playthroughs and thorough exploration of the game's environments. Some will even challenge you to make difficult and uncomfortable choices.
