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 onto the vent to the right of the crane, then onto 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, (it should be noted that if you are low on health and your speed is impaired, you cannot make this jump. Trying to do so in this state will kill you) 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.
