Campaigns

Campaigns (or movies) are storylines consisting of several chapters (levels, maps). At the end of each chapter, players are given awards for how well they did on certain aspects. If at least one Survivor escapes after the finale, credits will roll with the Survivors' final results. Much like the awards, the credits are completely cosmetic.

Each campaign features a "finale," in which the Survivors call for help and must face a gigantic horde while waiting for rescue to arrive. This includes several waves of Common Infected and Special Infected, as well as two or more Tanks (though hardly ever a Witch). After holding off the Infected for a certain period, the remaining Survivors (if any) head to the rescue vehicle.

Left 4 Dead 2
Left 4 Dead 2 currently has seven campaigns playable in all gameplay modes.

The game's campaigns are listed below, in chronological order:


 * 1) Dead Center ― In Savannah, Georgia, four complete strangers find themselves caught up in the chaos of a recent outbreak of the deadly Infection currently sweeping across the United States. Missing the last evacuation helicopter, they are forced to band together and head to the next known evacuation center at the mall. The Survivors shoot their way down through a burning hotel and through the Infected-swarmed city streets to a nearby shopping mall, where they find it overridden with zombies. With no other alternatives, they hope to use a famous race car being exhibited there to make their escape.
 * 2) The Passing - after escaping the mall the survivors reach a raised bridge in rayford, were they meet the 3 original survivors.upon asking for the bridge to be lowered so they can pass,francis explains that if they refill the generator on the other side of the bridge with gas he can lower it from up there. so the new survivors make there way through the town,past a wedding with a very pissed witch bride,through a underground museum,a sewer system,and finaly to the pert where the generator is.upon finding bill's body and the generator, the survivors start it up and with the help of the original survivors they finaly fill it and cross the bridge in the car as the original survivors sail away to saftey
 * 3) Dark Carnival ― Upon finding the freeway out of Savannah blocked by abandoned cars, the Survivors are forced to leave their vehicle and make their way on foot to the nearby Whispering Oaks amusement park, still partially operational and crawling with Infected. As a patrolling rescue helicopter circles overhead, the Survivors must make their way down the park's midway, through the Tunnel of Love, over the tracks of a rollercoaster, and past the exhibition barns to reach the park's stadium, where the pyrotechnics display of a rock concert stage may provide them with their only means of signaling the chopper pilot for help.
 * 4) Swamp Fever ― Unfortunately for the Survivors, the helicopter pilot that rescued them from Whispering Oaks succumbs to the Infection, and they are forced to kill him and crash-land the chopper in the Mississippi bayou. Finding evidence that rescue may be waiting deeper in the swamp, the Survivors must trek through an abandoned alligator farm, an airliner crash site, and a ramshackle shantytown where the local swampfolk made their last stand against the Infected. Eventually, they reach a giant plantation house, where they must hold off the relentless hordes of Infected until a kindly skipper named Virgil arrives with a rescue boat to take them to a rumored safe zone in New Orleans, Louisiana.
 * 5) Hard Rain ― As the evening sun begins to set, the Survivors learn that their rescue boat doesn't have enough fuel to reach New Orleans. Virgil drops them off in the derelict town of Ducatel, Mississippi to look for more. Their situation is further complicated by forgetting to bring signal flares to indicate that they've retrieved the fuel, as well as the sudden onset of a torrential downpour, the first sign of an incoming hurricane. The Survivors must move through suburban streets teeming with Infected and a half-demolished, Witch-infested sugar mill to reach a gas station. After obtaining the fuel, they must then make their way back through the mill and the town, both now flooded by the storm, to return to the dock, signal Virgil with the illuminated sign from a nearby Burger Tank, and escape before the full force of the storm hits.
 * 6) The Parish ― Virgil, who rescued the Survivors in Hard Rain and Swamp Fever, leaves them in New Orleans as he goes in search of more Survivors. The Survivors find the city completely overrun by the Infected. They have to make their way through the streets of the French Quarter, the military's abandoned quarantine zone, and an aboveground cemetery until they finally arrive at a partially collapsed table bridge. On the other side is a military helicopter waiting to take the Survivors out of the city to a flotilla of military-commandeered cruise ships in the Gulf of Mexico, where the last remnants of humanity in the area have regrouped, safe in the knowledge that the Infected can't swim...so far....

Storyline
The Survivors begin their trek on the top of a hotel, watching what was supposed to be their rescue helicopter fly away, leaving them stranded in Savannah, Georgia. They make their way down to ground level via elavator, and introduce themselves on the way down. They then decide to head to a local mall said to be an evacuation station for CEDA. Along the way, they aid a middle-aged man by delivering bottles of cola in exchange for firearms and a clear path to the evacuation station. Once at the mall, they discover it overrun with Infected and the health stations destroyed. With nowhere else to go, they fuel up a racing stock car put up for a show and make their escape.

The Survivors now meet another group of people near a bridge, which needs to be lowered to continue; however, a generator which is on the other side of the bridge must be filled first to activate it. The Survivors then walk by a park and into a apartment complex, which leads them to a wedding gazebo, where they encounter Bride Witch. After a long walk in the once-busy streets, they are forced to move underground and through the sewers. After reaching the surface, the Survivors once again meet the second group, which tells them to collect gas canisters to fill up the generator, while they are swarmed by the Infected. When full, the bridge is lowered and the Survivors run back to the car and escape once again.

The sun has set and the car is now immobile, the Survivors are forced to travel on foot over the stopped cars. In the distance, they see search lights, so they make their way towards them in hopes there will be someone around who can help. They discover the source of the lights to be a carnival which they traverse, finding nothing but Survivor-hating Infected. Overhead, a helicopter can be heard, so they follow it until they reach a stadium, where they use lighting equipment and loud rock-and-roll music to inform the pilot of their presence. The plan works, and the Survivors are rescued by the pilot. However, this was only true until he began turning pale and attempted an attack.

In self-defense, and perhaps protecting of his comrades, Nick kills the now-infected pilot, sending the helicopter crashing near some boxcars and a shantytown located in the heart of the Mississippi swamps. The Survivors go through an abandoned swamp city, go across a river in a mechanical ferry, head through swamps and bayou swarming with Infected, and reach the swamp town. Unfortunately, the Survivors find out that the town did not last and was overrun by the Infection. Through the advice of previous Survivors' graffiti, the quartet make their way to a Plantation house, where they are able to contact a boat captain to come and pick them up. They make it out alive, and continue down the Mississippi River, on their way to New Orleans, Louisiana.

Unfortunately, their ship is running low on fuel, and is incapable of reaching New Orleans. The Survivors are dropped off on the coast of a small suburban town named Ducatel with the task to find fuel for the boat engine. Unfortunately, the gas station across the street is out of diesel and a sign tells them that the next available gas is two miles away on the other side of a Witch-infested sugar mill. Along the way, the clouds start to roll in and rain starts to fall a little. Once they've gotten the gas needed to fuel their ship, a downpour starts up, and the roads begin to flood, forcing the Survivors to find other paths among the higher ground to make it back to the docks. Left without a method of signaling the success of their mission, they use the lights of a fast food restaurant, called the Burger Tank, to alert their vessel instead. Their plan works, and they are able to make it safely back onto the boat with enough fuel to reach their destination.

After a night's rest on their floating vessel, the Survivors reach New Orleans midday and set off to a supposed military evacuation set up on Veterans Memorial Bridge. After traveling through the city that the Infected took over, they soon become victims of their own saviors as the military begins dropping bombs in the city. After ducking and dodging bombs, they reach the bridge, where they are able to contact soldiers via a radio clutched in the hand of a dead man. They are provided clearance to cross the bridge to the evacuation vehicle on the other side of the bay. They finally find themselves flying away from their troubles, and making it out to safety as the bridge they were just on is bombed, and collapses into the bay.

Now the survivors are left by the military in a pine forest(most likley whilest asleep or drugged as when it starts you dont see anyone else) They start standing at the head of a river randomly lost in the forest they decide to just move on. upon following the river they find a camp of what used to be military and ceda,presumably dead, shown by the crashed vehicles,blood, and bodys.they go through a tunnel underground with a danger of being swept over a waterfall if they arnt careful, cross a bridge covered in wrecked cars and trucks,and pass through a junkyard where whats left of the military in this area bombs the overpass above the junkyard. finaly the team reachs cut-throat creek.using the radio in the safe room the team gets ahold of the pilot of a news chopper flying over the forest. getting told to head for the watch tower at the bottom of the creek the team sets out.fighting to the creek they hop down into the water and fight there way through.hopping of a small waterfall and passing a sunken boat until they finaly reach the tower,they climb up then climb the rope ladder from the top of the tower up to the chopper and they get the hell outta there.
