Complete walkthrough for Left 4 Dead's Dead Air campaign. Learn how to survive the greenhouse, navigate treacherous rooftops, and operate the crane to escape.

Walkthrough
  1. 1
    From the airport, grab supplies and use Molotovs to clear Infected from the greenhouse below.
  2. 2
    Descend stairs into the greenhouse and proceed through it to reach a roof.
  3. 3
    A Horde will attack from an adjacent building via a wooden plank; defend your position.
  4. 4
    Cross to the second building, enter an apartment through a window, and search for supplies. Beware of Hunters and Boomers.
  5. 5
    Jump to the gray rooftop, clear enemies, and climb a ladder to another roof.
  6. 6
    Walk to the end of this roof and drop to a ledge, then enter the next apartment building.
  7. 7
    Hide in a bathroom during a Horde attack or fight them off. A second pistol may be found in the living room or kitchen.
  8. 8
    From the kitchen, jump onto a parked big rig. Avoid the red car with an active alarm on the street.
  9. 9
    Check the building next to the big rig for supplies.
  10. 10
    Enter the Harbor View Hotel; the safe room is ahead. You can trigger the car alarm for fun before entering.
  11. 11
    From the kitchen safe house, head left to a fence and dirt mound. Clear Infected and climb the dirt mound to jump the fence.
  12. 12
    Use cardboard boxes to reach a yellow ladder on the left. Climb it to a staircase on an apartment building.
  13. 13
    Continue up the stairs until a blockade forces you to jump into a hotel window.
  14. 14
    Search identical hotels in the hallway for a second pistol or other weapons.
  15. 15
    At the end of the hallway, take the stairs on the right to the second floor. The room straight ahead is your objective.
  16. 16
    A Tank may appear here; if so, retreat to the roof for more space or hide in the bedroom.
  17. 17
    Jump onto the roof and destroy any Infected. Operate the nearby crane to create a path.
  18. 18
    As you start the crane, the Horde will arrive. Use the two fuel cans near the crane to create defensive positions against Infected coming from the hotel and rooftops.
Tips
  • Molotov cocktails are effective for clearing groups of Infected, especially in enclosed spaces like the greenhouse.
  • Be cautious of falling off rooftops when fending off Infected.
  • The red car alarm on the street is a hazard; avoid it and prevent Infected from triggering it.
  • The Harbor View Hotel section is short, and the safe room is immediately accessible.
  • For the crane section, strategically place the fuel cans to create barriers against the Horde.
  • There are known glitches to skip parts of the level, including bypassing the crane sequence by jumping across buildings and fences, and a method to descend early by jumping onto a tree.
