Mark of the Ninja is THE best stealth-action game I ever encountered. I'll keep it short.

-The art direction is top notch, animations are fluid and cut-scenes are great.
-Music and sounds are spot on.
-The story is satisfactory, dark and thought-provoking.
-Gameplay is fluid, controls are precise both on keyboard and controller.
-Multiple solutions to each and every encounter, you really can play the way you want.
-You really feel like a badarse NINJA whom everyone is afraid of. For dam good reasons, I might add.

All in all, it's as close to perfect as any game can get in it's respective category. Mark of the Ninja made me believe in the indie scene in the first place, and Klei keeps delivering.

10/10 would terrorize every guard again.
