Left 4 Dead/Runway Finale

You are at the tarmac, and a plane is landing to pick up survivors. However, it is coming in too fast and crashes; the only option is the other plane that need to be fueled first.

Route

 * Exit the safe house, and watch the plane take a landing. Climb down at the end of the platform to the right.
 * At the end of the area, there's a portable radio with the pilot trying to talk to you. He'll tell you that his plane needs to be fueled.
 * Start the pumping when you're ready - the noisy pump will attract the horde.


 * The mounted gun has good coverage, but can still be flanked. A few major paths the infected take towards the players fall under this minigun, but a smoker from behind can easily pull a survivor away from it.
 * Tank incoming when fuel is about half-way. He usually appears in scope of your minigun.
 * Tank incoming when fuel is near the top. He usually appears in scope of your minigun, but has the potential to flank.
