There are many different types of horror games out there, and there are still a lot of them out there!
Outlast running away from the hospital, Amnesia in a medieval setting...
There are really many themed games, which one is the scariest and the most memorable for you?
I find the Dead Space series to be really memorable.
It was also unusual that it was a gore horror game with a space theme,
The gameplay, characters, and directing are not forgotten lol
