It is scary and it sounds like you will be scared every second while playing the game ('cept for a few parts). I don't know what it would be on a "horror scale" but I'd say imo it's sometimes a little scarier than resident evil and sometimes as scary as like doom 3 (i thought it was pretty scary). Don't know how to really say it but I suggest you try a demo or play it at a friends house. It is overall awesome. I have it for PC btw.
