I didn't get my undetected achievment because i didn't notice somebody noticed me at the very end of the intro stage and i'd have to replay the entire game again to get it 10/10
As far as stealth games go i feel this one is one of the most replayable ones, very fun game with fun powers and multiple routes to takes.
A funny thing that happened to me is that when i first played it as a teenager i found it hard as fuck. I replayed it this year again, hardest difficulty, no upgrades and aiming to be undetected the whole game and it wasn't that hard.
