Campaigns

Campaigns (or movies) are grouped sets of environments used for gameplay in Left 4 Dead and Left 4 Dead 2. Campaigns are aesthetically presented as if they are individual zombie movies, complete with a poster on the loading screen for each one, and usually consist of several chapters (also referred to as "levels" or "maps"). Chapters are typically played in order, following a narrative in which the Survivors travel from a start point in the midst of the zombie apocalypse to an end point where a rescue vehicle to safety awaits, surviving the onslaught of the Infected as they go. The exact process of experiencing a campaign's content depends on the gameplay mode being played, with some modes utilizing single chapters of a campaign for each game rather than progressing from one chapter to the next.

Left 4 Dead initially released with four campaigns, while Left 4 Dead 2 initially released with five campaigns, with both games receiving additional downloadable campaigns after release. On Steam, downloadable campaigns are added to the games as free updates and are playable simply by purchasing and installing the games. On Xbox 360, downloadable campaigns must be purchased (excluding "The Last Stand" for the first game, which is available for free) and manually downloaded from the Xbox Live Marketplace.

The majority of the official campaigns encompass a larger narrative when played in a particular order, but this is not enforced by the game. The Director-based gameplay of the Left 4 Dead games encourages players to enjoy any campaign multiple times.

On the PC version of the game, custom community-made campaigns are also supported, which may vary in their structure compared to official campaigns (for example, some may simply serve as "map packs" for modes that only use a single chapter of a campaign per game, like Survival).

Left 4 Dead


Left 4 Dead currently has six official campaigns playable in Campaign and Versus, with a seventh only available in Survival.

At least one additional campaign was planned and partially developed, but ultimately was cancelled and not officially released as content for the game ― see below in Cut Campaigns.

The game's campaigns are listed below, in chronological order:
 * 1) "No Mercy" ― In Fairfield, after a narrow escape from the Infected, the Survivors focus on moving towards a Hospital for evacuation by a passing News 5 helicopter. The Survivors move from an apartment building to a subway station, then a sewer, then Mercy Hospital, before arriving at the "Rooftop Finale".
 * 2) "Crash Course" ― See below in Downloadable Campaigns.
 * 3) "Death Toll" ― The Survivors have finally made it to Riverside. Due to the pathway blocked on the abandoned highway, the Survivors follow the drainage system of Riverside, go to a church, traverse the town of Riverside, and finally arrive at a boathouse on the riverbank. There, the Survivors wait for rescue from a civilian fishing boat.
 * 4) "Dead Air" ― With the Survivors stranded in a large greenhouse full of Infected, they witness a plane fly by overhead. Deciding the best way to escape the city is via the airport, they make their way through a metropolitan area, over rooftops, a construction site, an air station terminal, and finally, a last stand at a Runway Finale. There, the Survivors see a C-130 Hercules plane that has run out of fuel, and needs help refueling.
 * 5) "Blood Harvest" ― Lost in the middle of a thick forest, the Survivors follow the path to a trainyard, and through a repair warehouse. Following the railway lines, they move past a bridge, a train station, and finally to a "Farmhouse Finale". With nobody in sight, the Survivors call via a radio to the military, and from there, wait for an armored personnel carrier to pick them up. But in the meantime, the Infected have discovered their location...
 * 6) "The Sacrifice" ― See below in Downloadable Campaigns.
 * 7) "The Last Stand" ― See below in Downloadable Campaigns.

Downloadable Campaigns

 * 1) "The Last Stand" ― A non-canon one map campaign only available for survival mode involving a lighthouse setting. It consists of a what-if scenario involving the survivor's reaching a dead end with no way back. An expanded remake of the campaign, no-longer exclusive to survival mode, was later released for Left 4 Dead 2.
 * 2) "Crash Course" ― After escaping Fairfield in "No Mercy", the helicopter crashes in an area close to the abandoned highway in "Death Toll". With the pilot having fallen to the Infection, Zoey is forced to kill him mid-flight. Having survived the crash landing intact, the Survivors make their way across alleys to a garage where they find an armored delivery truck on top of a vehicle elevator, just out of reach.
 * 3) "The Sacrifice" ― The aftermath of "Blood Harvest" and the comic are told in "The Sacrifice". The Survivors arrive in a shipyard by train and must battle their way through constant hordes, an imprisoned Tank, and some rather bothersome birds in hopes of finding a working sailboat. Unfortunately, the almost flawless plan to raise the bridge and escape the largest horde anyone has ever witnessed goes awry after one of the generators malfunctions. In order to save the others, one of the Survivors must sacrifice themselves so that the others may proceed. Canonically, this Survivor is Bill, but in the campaign, anyone may do so. The campaign was also released at the same time for Left 4 Dead 2.

 * 1) "Dam It" ― An unfinished campaign developed by Turtle Rock Studios that was originally made to bridge the gap between "Dead Air" and "Blood Harvest". It is playable in its unfinished form via an add-on.

Storyline
Having just survived an encounter with the Infected, the Survivors prepare themselves on a rooftop in Fairfield, only to hear a helicopter flying overhead announcing evacuation at the city's Mercy Hospital. Already acquainted with one another, the Survivors proceed to the hospital, and, after fending off the Infected, are picked up by the helicopter's pilot.

Minutes after escaping in the helicopter, the pilot turns into an Infected. After Zoey shoots the newly turned pilot, the helicopter crashes in the outskirts of Riverside, and the Survivors head off in search of a rescue vehicle. Finally, they discover an armored truck in a garage and use it to escape.

The Survivors are once again stranded when they discover that the bridge is destroyed. They abandon the truck and head into the town of Riverside. Along the way they find a crazy guy in a church and then find a boat house at a lake. The Survivors use this to call for rescue from John and Amanda Slater, two people with a nearby boat.

The Survivors are left to die by the Slaters in the city of Newburg, where the team takes shelter in a rooftop greenhouse. A low flying C-130 plane gives them hope that the local airport might still be running evacuations. Upon reaching the airport, the Survivors must defend it while the pilot prepares the plane for flight before escaping.

When the Survivors reach Allegheny National Forest, they decide to head towards a military rescue outpost. Upon reaching a farm house, the Survivors use a radio to request rescue from the military. They then hold off the infected until an armored personnel carrier picks them up and transports them to Millhaven's military base.

The military locks up the Survivors and a doctor explains to them that they are carriers. When Lieutenant Mora sounds the base's alarm to command retreat, the infected attack. Louis saves the lives of soldiers Jeff and Annie, who in return allow them to carry weapons to fight the infected with. Meanwhile, Bill, Zoey, and the doctor head towards the armory as well. They all meet up there and head across the base courtyard, towards an old train. When they get there, Jeff and Annie leave to go with the rest of the soldiers, whereas the Survivors and the doctor head towards the train. However, when they reach it, a Hunter kills the doctor, and the Survivors continue south on the train.

The train comes to a halt in Rayford, Georgia where the tracks end, where the Survivors' new plan is to find a boat and travel somewhere free of the infected. However, on the first boat, Louis finds a dozen Witches on board who nearly rip his leg off. They find another sailboat boat, but when they try to raise the obstructing bridge, one of the generators breaks down and the bridge stops halfway up. The Survivors now face an enormous horde plus 3 Tanks. Seeing that there's only one way this can end, Bill jumps down and fights his way to the generator that stopped and turns it back on, making sure that the bridge raises with the other 3 Survivors on it, but committing the ultimate sacrifice as the Infected eventually kill him. A little while later, the remaining three Survivors encounter four other Survivors who arrive in a racing stock car on the other side. They help them cross the bridge and see them on their way. When the other Survivors have left, Louis, Zoey, and Francis take the sailboat to inhabit islands far away from all of their troubles, and rest out until the apocalypse is over.

Left 4 Dead 2


Left 4 Dead 2 currently has fourteen campaigns playable in all gameplay modes, six of which are from the original Left 4 Dead and two of which are non-canon campaigns developed with assistance from the fan community ― see below in Downloadable Campaigns.

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. Just 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" ― See below in Downloadable Campaigns.
 * 3) "Dark Carnival" ― Upon finding the freeway out of Savannah blocked by abandoned cars, the Survivors were 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 provides 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 succumbed 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 fuel. Their situation is further complicated by forgetting to bring signal flares to indicate that they have 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 the 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 sugar 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 them.
 * 6) "The Parish" ― Virgil, who rescued the Survivors in "Swamp Fever" and "Hard Rain", 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.

 * 1) "The Passing" ― After escaping the mall in "Dead Center", the Survivors are stopped by a raised bridge. They encounter the Left 4 Dead Survivors taking shelter on the bridge, who inform the new Survivors that they will lower the bridge if the generator is refilled with gasoline. The Survivors make their way through the streets and buildings, past an interrupted wedding ceremony, through some sewers, and to the generator, where they discover that one of the Survivors at the bridge (Bill) has passed away. With combined effort from everyone, the generator is filled, and the Survivors were able to lower the bridge to continue their adventure onwards in their stolen race car.
 * 2) "The Sacrifice" with "No Mercy" ― A port of said campaigns from the first game (see above for descriptions). "The Sacrifice" is the only campaign to be released for both Left 4 Dead and its sequel at the same time.
 * 3) "Cold Stream" with the original Left 4 Dead campaigns ― A DLC Pack which includes a non-canon campaign developed with assistance from the fan community, as well as ported versions of "Death Toll", "Dead Air", "Blood Harvest" and "Crash Course".
 * 4) "The Last Stand" ― A remake of the survival campaign from Left 4 Dead developed by the community, it features a what-if scenario where the Left 4 Dead survivors take a different path. The pack also comes with 26 new survival maps and 4 new scavenge maps.

Cut Campaigns

 * 1) Cabin in the Woods DLC ― During the development of the movie The Cabin in the Woods, Valve made a deal with the original production studio, Metro-Goldwyn-Mayer (MGM), to make a themed DLC. However, the plans stalled as MGM delved into financial problems and eventually declared bankruptcy. Eventually, Lionsgate picked up the distribution rights and released the film, but the months-long delay made Valve shelve the plans for a DLC. According to Drew Goddard, the director of The Cabin in the Woods, the DLC was going to be set on the same universe of the movie with the Survivors beginning their journey on the titular cabin then descending into a military complex underground as campaign progressed. The DLC would also feature special enemies and/or skins to represent the creatures seen on the film.

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 elevator, 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 60-year-old man by delivering bottles of cola in exchange for firearms and a clear path to the evacuation station. Once at the mall, they discover that it was overrun with Infected and the health stations have been 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 walk by a park and into an apartment complex, which leads them to a wedding gazebo, where they encounter The 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, who tell them to collect gas canisters to fill up the generator to lower the bridge, while they are swarmed by the Infected. When the generator is full, the bridge is lowered and the Survivors run back to the car and escape once again.

Some time and many miles later, the Survivors are forced to abandon the car and travel on foot, due to the highway being clogged with abandoned vehicles. In the distance, they see search lights, so they make their way towards them in hopes that 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 flies around, so they follow it until they reach the 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, he begins to turn pale and attempts to attack them.

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 the 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 were 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, Virgil's boat runs 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 of finding fuel for the boat engine. Unfortunately, the gas station across the street is out of diesel and a sign states that the next available gas is two miles away on the other side of a Witch-infested sugar mill. Along the way, the clouds started 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 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 helicopter 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.
