I am fascinated by games with 2D art that still manage to give you a good scare. I guess what I find interesting is if a game can manage to translate the scares and audio design which we know from 3D environments and movies. I have never really played any though. I would love to hear some suggestions, especially with Halloween coming soon!
Metroid Fusion has some very scary segments, and my understanding is that Metroid Dread does some of the same things, though I haven’t played through that one yet.
I finished Dread, amazing game, but I don’t remember any scary sections.
“Scary” may also be the wrong word; “tense” might be closer to the mark. In Fusion there are these sections where you’ll be exploring and then suddenly your doppleganger will show up and start hunting you. It’s surprising and actually pretty unnerving; you have to get away, but the thing can move basically as fast as you can and there’s really not much room to maneuver. I was under the impression that the “EMI” sections in dread were basically a refinement of this, but maybe I was misinformed.
