Just finished the campaign and even though it's short I can honestly say it's the best campaign I've played in a while.

True. It's a nice story indeed. Wish it was a bit longer.
Also, I loved the ending. Reminded me of Max Payne 3 a bit. .

Also, the game was a bit too easy even on Post-Human. Play using stealth, and be patient, and it was easy, I think.
