To me there's two kinds of horror. Number 1 is the classic scare jump, lot's of violence and gore, strobe effects and what-not. Number 2 however is more subtle, there isn't that much action it's more the atmosphere, the ancitipation that something might happen at every turn. For me, this game clearly falls in the second category, but it isn't able to keep the tension up all the time. But I think that's because it delivers more than just the fear of the unknown, it also delivers very, very shocking scenes. Not shocking because you're creeping through some corridor and some alien is stalking you, or because something is able to control minds or a powerful AI taking control of everything. No this one is more sinister, while many horror settings focus on things we don't know or can't or fight and are therefore scared off, this one has it's focus on something we totally can understand and relate to, humans. Humans are capable of great things, so is the human mind. And history has shown that humans are able for experiments and methods that really ask the question, when is something/someone violating humanity? It's difficult to draw a clear line, but this game crossed it anyway. There are some very sick minds in this game and learning about their doings and trying to understand why they're doing it left me feeling very uneasy and ill. In conclusion, it's a great game, the characters seem a little bland and sometimes I hated the controls but all in all it's a great game. Not a fun game though.
