Awesome level design, outstanding missions with high variety of situations, and beautiful scenarios. The player has a lot of freedom in deciding how to approach the objective because the areas are very open. Also, there are some brillant puzzle elements.

It is significantly better than Dishonored 1, in all aspects of the game. It reminds me old thief games in some ways you play the game (if the player chooses a stealthy approach). It's like a deus ex (in a different world) at its best.

There is only one problem: sudden fps drops and some technical imperfections.
But definitely, an impressive game. A milestone.
