The Crane

The Crane is the second chapter of the third campaign, Dead Air. Essentially a series of rooftops and offices.

Tips
NOTE: This is considered an exploit! It is possible to skip the crane crescendo. To do it, you jump on the fence around the crane. You follow it around until you reach the gap facing the next rooftop. You run and jump, and then land on an electrical box, then up on the next roof. From the roof over you can jump into the tree, with a substantial health hit, then make it to the ground. This effectively skips the rest of the map.
