I never really gotten into it. Well sometime maybe.
It's amazing. It starts out and you're like "ehh...atmosphere is nice. It's kinda creepy. Beating homeless people up is fun." But by the end, it easily becomes as terrifying as Amnesia...and it's one of the few games I've played that gives its violence a real visceral, queasy feeling rather than just "oh, look... more blood and guts flying everywhere." Combat and the infrequent gunplay all feel brutally satisfying. Teeth go flying, you can feel the impact running down your arm...guns go "BOOM" and are handled like real guns (hard to aim, no ammunition display, can be used to melee, etc) But the things you see happen and find are downright disturbing. The game's whole atmosphere of hidden violence, disgusting perversion, and decay gives everything a vividly sickening gutpunch. It's American horror done right (I'm using "American horror" to refer to the genre, since I have no idea where Monolith itself is actually based).
