Swamp Fever

Swamp Fever is Left 4 Dead 2 ' s fourth campaign (originally the third, with The Passing DLC shifting campaign order).

Swamp Fever spans four long chapters and takes place in Louisiana-type bayous and swamplands near a shanty town called Village En Marais.

Chronologically, it follows on from Dark Carnival and picks up the Survivors' story in wake of Nick shooting the helicopter pilot due to the latter becoming an Infected. Once they have shaken themselves out following the helicopter crash, the Survivors find themselves stranded in the middle of nowhere with their only route to safety going through a gator farm, a downed commercial airliner, swamp villages and finally at an abandoned plantation where their rescue awaits them. Along the way, they meet a new breed of Infected, the Mud Men.

The campaign culminates in a finale wherein The Survivors must hold out until rescued by a fishing boat captained by Virgil― a likeable and public-spirited Cajun.

Swamp Fever and Cold Stream are the only campaigns to contain Mud Men (a class of Uncommon Infected) who are agile, hard to spot and blur player's vision with mud when attacking. Similar to Jockeys, they move by scuttling along on all fours, but they are of a bigger size and so are easier to hit.

Below is a complete list of video walkthroughs of the 5 levels:

Behind the Scenes
Originally the Uncommon Infected in this campaign were the Fallen Survivors instead of the Mud Men, but they were cut from the game and later put in The Passing. Also, the Heavy Machine Gun at the finale was going to be in front of the entrance of the house (as can be seen in the Zombie Survival Guide), not on the 2nd floor balcony.
