Arizona Sunshine is a great zombie game, it's not very scary though but can get quite intense when hordes start appearing.
I bought Narcosis last night, it's a VR game that can also be played 'flat' and have only played the first two levels so far and nearly filled my trousers a few times lol
Has plenty of jump scares, the atmosphere is VERY creepy, tense and stressful thanks to the excellent music, sound effects and the isolation and claustrophobia you feel due to being confined to your diving exoskeleton thingy. It isn't as scary as Dreadhalls so far but is right up there with Monstrum (which I THINK might also be a game that be played in VR or 'flat', but if you go to buy it please check first because I might have that wrong!).
Outlast 2 was released on Steam today I think, no VR support though which is disappointing, particularly since the first game is supposed to be fucking terrifying in VR using VorpX. Won't be long before we see Ralf, the developer of VorpX, sets up a profile for this though I reckon.
And in January next year we'll probably see Resident Evil VII VR being released. Can't wait for that one!!!
Scary games are awesome!
