Plot
The plot is similar to Left 4 Dead 2 it involves the aftermath of the the Infection one week after the events of the previous game, now being around three weeks after the first infection.

The story starts around night in Monroeville, New Jersey. As the last rescue helicopter leaves the building, four unlucky Survivors climb up the hotel to find that they were just a couple of seconds too late. With this newfound predicament, the group decides to go to a mall, where it is said that another evacuation center is still in operation. When the group reaches the mall, they find that it has been overwhelmed by the Infected. In desperate hope, they decide to pierce deeper into the building in hopes that the evacuation center was simply deeper inside. It turns out that the center was decimated, and all the CEDA agents are either dead or infected. In despair, the group wanders into the mall's atrium and finds a functioning stock car, albeit without gas. A new idea appears in their heads; to scrounge around the atrium in search of gas cans, for the purpose of filling the car's tank. This proves successful, and the Survivors escape Savannah.

During their escape, the group stops at a bridge raised by Diana Cross. She meets the Survivors and inform them that they cannot lower the bridge for the group because the generator used to lower the bridge is out of fuel, and they must tend to one of their own who is wounded. After battling through a wedding with the Witch bride, the streets, and a "historical sewer," the Survivors then meet up with Diana. After Diana agree to help by defending them from higher ground, the Monroeville group is able to fend off most of the Infected, find gas cans, fill up the generator, cross the lowered bridge, and drive off while exchanging farewells as they continue to Grafton.

The escape car works well until the Survivors find that the highway is blocked by abandoned vehicles, seemingly going on for miles. Finding no other way past, the Survivors leave the car behind and proceed by foot. When they go below the overpass, they see searchlights still online in the distance. The group then decides to head for the lights, in hope of finding some uninfected people. The searchlights turn out to be originating from Whispering Oaks Amusement Park and Fairgrounds, which is now a hunting ground for a large number of Infected individuals. The Survivors wander through the park for a bit of time until they see a helicopter fly over head. Newly inspired, they decide to hold a rock concert set up for the Midnight Riders in hopes that the loud music and Grammy-award-winning pyrotechnics will attract the helicopter. When they finally enter the amphitheater, they activate the controls and find out that the sound is attracting a massive amount of Infected along with the helicopter pilot. After much fighting, the helicopter finally decides to make a pick-up and the Survivors barely escape the abandoned carnival.

But once again, luck is not on their side, and the helicopter is forced to do a crash landing after the helicopter pilot turns out to be infected and was shot by one of the Survivors. The Survivors exit the wrecked helicopter to find that they landed in a bayou. They pass through a small village and find that the populace decided to take matters into their own hands and barricade themselves against the Infected. Without any other option, the Survivors decide to try to find the barricaded area. They travel through a swamp, fight numerous Infected, and find a crashed airliner in their path to the safe area. When they reach it, they discover that the townspeople were overwhelmed by the infection, but luck turns out to be on their side this time as they find someone wrote on a wall about an old plantation house and a nearby dock. The Survivors head toward it and find a radio, and manage to contact a man named Henry Winters who has a boat further down the river. Herny and the group have a short discussion via radio, and the Survivors tell him that they are at the plantation home. Herny recognizes the location and begins to navigate his way to their location. After the Survivors fight off hordes of Infected, Herny arrives and blows down the gates that blocked their way to the river, the Survivors then jump on the boat to safety.

However, along the way, Herny's boat begins to run low on fuel, so he drops the Survivors off by a small town in West Chester, Pennsylvania, with instructions to get diesel for the boat from the gas station across the road. Unfortunately, this gas station is out of fuel, and the Survivors forgot the bag of guns, and have to travel two miles east, navigating through a Witch-infested sugar mill to collect gas. Even more unfortunately, they have to once again walk those two miles back, except uphill, in the midst of a torrential downpour. The forgotten bag of guns also held the flares to contact Virgil. So they decide to signal Herny by lighting up the Burger Tank sign near the dock. They defend themselves once more against hordes of Infected until Herny finally arrives for them.

At long last, Henry drops the Survivors at a waterfront in Grafton. He then leaves, saying he is on his way to find other Survivors. The group of Survivors then fight their way through the waterfront, a park, a cemetery, and the French Quarter, coming to a bridge in the middle of being bombed by the military. On the other side of the bridge is a military chopper about to leave. The Survivors manage to contact the military over the radio and then run across the bridge to the awaiting chopper pilot who carries them to a military cruise ship.
