Runway Finale

The Runway Finale is the fifth and final chapter of the third campaign, Dead Air.

The survivors reach the airport runway in time to see a jet air-liner crash (maybe the plane from the beginning? That would be bleak). They then make their way towards a military plane and establish radio contact with the pilot.

The ground team of the airport seem to all be dead or infected - the Pilot informs the survivors that the plane is in desperate need of refueling. After opening a valve on a connected fuel tanker, the plane beings to re-fuel and the pilot gives the group notification as the tank begins to fill.

The survivors must hold out until the plane is air-worthy against waves of common Infected, several  Tanks and other  Special Infected. A minigun turret helps in this regard.

Eventually, the plane is filled with fuel, the engine starts, and the survivors must board the plane from the opened hatch at the rear, evading a final rush of Infected. Success grants a view of the plane's successful departure, followed by the display of the campaign credits.
