Beat the game (on hard) today. Triggering no alarms, killing everything silently until I had learned all the abilities. After that, I just quickly sneaked my way past everything . The final boss was a joke, indeed. I won't spoil anything, let's just say that it is the easiest final "boss fight" in any game I can remember playing. As I said in my impression, there is basically no AI for the guards. They are scripted, how they react, where they go if alerted and all that. I saw the levels more like a puzzle to solve. How do their patterns look when they move and how should I take them out without getting detected, or the corpse getting detected. You can hide corpses, so you need to make sure you have the time to do that. The best thing I can say about the game is that I enjoyed some of the levels. Some of them were fairly big and I would reload once or twice, not because I got stuck, I just wanted to see if I could tackle it differently. Many times this was the case.

+-Levels had a good layout, but the save system made some of them annoying.
I liked it in the beginning, started to get annoyed in late chapter 2 and chapter 3. Started enjoying it again in chapter 4-6. The game should probably take you 10-12 hours to beat on hard if you intend to play it like I did. You can finish it much quicker if you just want to rush through it. I could easily see a speedrun of 2 hours or less.
My final score: 6/10.
