Masterpiece of Immersive Sim, a game full of value, full of heart and soul.
Master class of art direction, level design, world building.
Top-notch gameplay design supports multiple play styles : gun blazing killing everyone or be a stealthy ghost and leave everyone alive. Great replayability,
The game also has a good story with some twists and turns.

Arkane Studio and Harvey Smith is definitely one of the best game developers and no doubt my favourite.
