Hi. I've been coming up with some ideas that would make horror games scarier and more immersive, and I was wondering what the Frictional Games community could come up with. My idea is an enemy that always stays in your peripheral vision, in the darkness. When you turn to look at it, it would seemingly vanish because it moves incredibly fast. The farther you get into the game, the more frequently it would appear. It would make no noise, and would never harm you. This is similar to a fictional creature dubbed
SCP-372 which always stays in your blind spots.
So, what do you all think? What would make horror games scarier?
