You'll find a dark and contrasted city sprawl that threads the needle perfectly between making you feel like the title of the mission without you being absolutely lost. You're always sorrounded by tall and meanicing stone walls reminicent of a Thief 1 city, but one that has grown to use both electricity and in scale; you'll be looking up just as much as you'll be looking at front, and you'll be rewarded for it with alcoves, secret passages and high rise alleyways that give you both alternate routs and unique entry points into buildings otherwise innacessible. Map is big, with plentiful of smartly placed mini secrets that reward your exploration and wits. You have to carry a corpse for a short section, a gameplay gimmick I'm personally not fond of, but it's short. Definitely top 15 best FMs I've ever played.
