I just completed the game...in 3.6 hours (according to Steam).
What the fuck? This isn't a sarcastic question, but did I miss something? Are there alternative endings/paths through the game? I read all the documents and checked every inch of every room, or at least I think I did haha. I've heard some reviewers talk about it being a "9 hour game" This can't be right. I'm not one of those who demands a certain length of game for my buck, but when I'm told it's a certain length and it ends 6 hours earlier than I expected...well, it's a bit jarring to say the least.
I enjoyed the game and would recommend it. Great graphics, great "feel" to the mechanics for the most part, AAA-quality all around for sure. And, despite being shocked that I completed the game in 3.6 hours, I do think it was an adequate length for what the game has on offer (and for the price). I just felt virtually nothing resembling fear throughout, which is obviously the main selling point for a horror game. The chases got more frantic and intense as the game progressed, but no more so than a chase in Mirror's Edge, which isn't even a horror game!
The story...I'm not entirely sure what it was about, and I'm not entirely sure why it ended the way it did. I'm scratching my head about a few elements which became central towards the latter part of the game. But that's probably more the fault of my coffee-addled brain than the writers' ineptitude.
