Unfortunately I spoiled myself on the big plot twist but luckily that didn't lessen the impact for me. Atmosphere is just as important as the previous 2 games in the series and it unsettled me just as much, despite the "better" graphics taking away a lot of the ambiguity of the monster designs that made them so terrifying in the first place. Don't get me wrong, they're still terrifying.
Also Heather is a great protagonist and probably my favourite out of the first 3 games
