Dishonored Walkthrough: Rescuing Emily, Eliminating the Pendleton Brothers at the Golden Cat

This is a full mission walkthrough of the Golden Cat area and the Distillery District. It also shows how to complete Slackjaws' mission and how to complete this mission non-lethally. It shows how to rescue emily and eliminate the pendleton brothers non-lethally. I am also doing this without any upgrades, so I am not going to pick up any Bone Charms or Runes or any other loot since it is unnecessary.
