The game is fairly optimized well on the PC.
The game is fun for old school Sniper Elite fans especially with the X-Ray kill cam.
There are new mechanics implemented into the game where when you fire your weapon enemies may hear the sound and you are required to move to a different location from being detected.
The AI is pretty bad in normal settings where you can walk right up next to an enemy or in front of him and knife him.
There are some confusing way points.
Overall the game is pretty good
