Digital Spy: "'The Knife of Dunwall' isn't a bad piece of downloadable content, and is in fact good value for money if you're into collecting everything or playing higher difficulty levels. It's fun at times for the same reasons the main game was.
But a number of disappointments make the add-on a less interesting and fulfilling experience. The strong opening mission aside, it pales in comparison to the original Dishonored." 3/5
