Story
In this game you play as both Corvo and Emily which allows you have a bit more variety while you’re playing and keeps you engaged however, unlike the first game you don’t feel as engaged in the story and its easy to get lost.
Abilities
As with the first game Corvo has a lot of abilities he is able to pick from which allows the player to approach each mission differently. With you now being able to play as Emily, the player has a new set of abilities which allows the characters to feel unique.
The World
Like in the previous iteration of the game, the world around you is affected by how you act and the actions your character takes. This is an important feature to carry over and works well as it makes the world feel lived in, if your able to make positive changes to the world you could end up picking up smaller missions from the locals which definatly adds to the feel of the world.
Difficulty
What they have done a better job with this game is making the AI feel realistic and alive so you may have to work a bit harder to trick the enemies if you’re going for a stealthier run but this feels more rewarding and satisfying when you get it right. There are also a wide variety of enemies and they can’t be treated the same so through playing you have to learn how to handle each of them differently.
Stealth
A common way to play through this series is to use stealth and I believe they got very close to perfecting it in this game as you feel very satisfied when your able to get a low chaos run even if it has taken you a couple of runs. There are also a couple of missions which are built for it and are very enjoyable to play and also re-play to perfect.
