Brilliant level design, great models and textures, good graphics, a fantastic world rig and true first person.
No weapons was a plus as well.
The first encounter with one of the asylum's tenants was fairly intense but it wasn't hard to figure out his path. The tasks that you need to do before proceeding were repetitive: it was either turn two valves and continue on or it was turn on a couple of generators and move on or find fuses and press the progress button, with each task there was always an obstacle: either one of those big guys or a guy with a nightstick; again, they were fairly easy to circumvent and didn't really make me feel uneasy.
The game on its own wasn't really scary: it seemed to rely on jump scares all the time which did get more and more annoying especially when you're placed in a huge room with one of those big guys and without your night vision camera you're screwed. The batteries in that camera died out extremely fast so you use up batteries a lot.
It was very up front: if you're not scared yet then wait until you walk through this door and find blood all over the floor, human organs strewn all over the place, severed limbs and decapitated heads. Everything was very upfront and didn't really give me much time to create my own fear - scares were abrupt and repetitive and it seemed as though the whole idea of horror was forced down your throat and that really destroyed the whole horror aspect and made it feel more like a chore than something to provide entertainment.
The game seemed to have started out on a fairly good note and then it progressively got repetitive and boring, it gets to a point when you just want it to end and that point is reached fairly early in the game.
