I challenge anyone not to get more than a few scares playing this game. Another indie title but from experienced developers who set out to make their passion project, Outlast shines through its execution and is one of the purest horror games I've played.
There's no way to defend yourself beyond just mashing buttons to escape and run from some of the inmates. The object is to hide and use the darkness to your advantage.
The game carries many genre influences from films such as REC and The Blair Witch Project, and it uses them to full effect as you work your way through the asylum completely terrified and defenseless. So the first-person perspective here is a completely natural fit that works when looking down the lens of a camcorder, constricting your field of view, and ratcheting up the horror.
