Swamp Fever

Swamp Fever is a campaign spanning four chapters which takes place in a "swampy" location in Left 4 Dead 2 after evacuating from Savannah. The Survivors reach this swamp and escape from it in a fishing boat similar to the one in Death Toll.

Swamp Fever is the only campaign that contains the Mud Men—Uncommon Infected that are hard to spot and extremely agile compared to the Common Infected.

Below is a complete list of video walkthroughs of the 4 levels:


 * 1) Plank Country
 * 2) The Swamp
 * 3) The Shantytown
 * 4) The Plantation

Please know that the gameplay videos are on each campaign's info page not on each map page.

Trivia

 * "Swamp fever" is a term given to a number of diseases that are acquired in wet, swampy environments.
 * Some of the walls in a shanty house found in Swamp Fever can be broken off with weapon damage.
 * Paratroopers can be found throughout Swamp Fever, for unknown reasons they are not Infected.
 * Swamp Fever was the first campaign revealed to have 4 chapters (Dead Center was the second), as opposed to the usual 5. However, it is supposed to have the same duration as 5 levels, so it feels like a 5 level campaign.
 * All four chapters have a Crescendo Event, with the exception of the finale.
 * The train the Survivors start in some Swamp Fever videos has not been removed the same way police car was removed from Dark Carnival. Although it hasn't been removed, the Survivors still occupy the train car and Ellis complains that Nick killed the Helicopter Pilot, in a similar manner to Crash Course. This brings up another thing, such as weapons and the helicopter crash itself. A theory could possibly be the Survivors lost their guns while the pilot was becoming Infected and they moved away from the remains of the helicopter to a safer place.
 * When in spectator mode, the crashed helicopter can be seen behind the train the Survivors start from.
 * This campaign is set in dawn, from just before the sun rises to just after. The final chapter the campaign is in daylight.
 * Just like the Helicopter Pilot in the Left 4 Dead, the Helicopter Pilot in Dark Carnival became a zombie. Afterwards, Nick killed him, bringing them in this campaign.
 * The Stand-off Plantation finale features four Tanks. One after the first wave and two thereafter, along with the fourth appearing along with the rescue vehicle.
 * The crashed Airliner in The Swamp could be related to Metro International Airport, as the destroyed airliners in Dead Air have the exact same red orange stripe.
 * In the area containing the river boat Crescendo Event, there is a Charger strung up on a signpost. It is in the shape and pose of the Lambda symbol, continuing Valve's tradition of sneaking the symbol into the Left 4 Dead titles.
 * This is the only campaign that lacks a hidden Left 4 Dead poster in its loading screen.
 * The Director spawns Ammo Packs and Grenade Launchers in this campaign more than any other campaign.
