Five Nights at Freddy's is a horror game. My AS11 has never played it, but we have watched DanTDM's YouTube videos of him playing it. There are lots of puzzles to solve, and quite a few jumpscares. My son loves scary things when it is safe (if that even makes sense). I'd probably let my son play it if he asked, mainly because he knows his limits and will not play it if he finds it too scary.
