The Construction Site

The Construction Site is the third chapter of the third campaign, Dead Air. In this chapter, the survivors exit the safe room and walk down an alleyway to find themselves in an unfinished construction site. The survivors find the way to the next alley blocked, and use gas canisters to burn the barricade that is in the way. Upon lighting the gas, a horde is alerted, and the survivors must fight off the horde until the wood is burned away. Once this is achieved the survivors cross a street to a power plant. After going through the power plant, they come out under a collapsed highway bridge in front of the airport, with the remains of a crashed plane tossed about the area. The survivors fight their way across the highway and into the airport car park, they cross the skybridge into the terminal and into a safe room at the end of the chapter.

Tips

 * It's worth it to note that the survivors can light the barricade on fire and run back to the saferoom, from the second level of the construction site, to fight the horde a cheap, easy way.


 * The series of raised platforms is a good, and obvious, spot to defend yourself from the horde, and often comes with a supply of Molotovs or Pipe Bombs.

It is possible to skip lighting the barricade in this level. There is a small staircase in front of the barricade. Jump onto the railing, run down it and leap over onto the electrical boxes on the wall to your left. It will probably take a few tries, but it can be done. Once on the boxes, run down the length and jump towards the barricade. If done correctly, you'll land on top of the barricade and be able to jump down to the other side. Keep in mind that this can't be done if your low health has impaired your speed, and it's wise to keep one person on the barricade at all times until your entire team has made it past, since it's impossible to get back over it or shoot through it to help a teammate in trouble.
 * NOTE: This is considered an exploit!
