Plank Country

Plank Country is the first chapter of the campaign Swamp Fever in Left 4 Dead 2. The map begins with the Survivors leaving a derailed train that fell in front of a small town, which they had been using as a temporary safe room. The townspeople, who had been resisting both help and refugees, believed that they could barricade themselves in, seeing as it bordered a swamp. Unfortunately, judging by the lack of other Survivors, the plan failed, and everyone has either been killed, been infected, or simply left.

The box car has basic starting supplies; four first-aid kits and tier 1 weapons. Considering the fact that the train hinders progress further down the highway, the only way to go is through the abandoned town. The Survivors head through a village of shacks, and eventually reach an old cable-ferry where the crescendo event kicks in. Not only are the Infected attracted to the sound as it moves toward the Survivors, but they keep coming while the ferry goes back. In addition the survivors can fall into the river to their deaths. After the event is over, the group wanders through the swamp until they find the safe room at the end of the chapter.
 * Note: Do not try to jump to the raft,especially if it is close, you will either fall in the water, or be hanging from the edge,and be crushed to death by the float as it arrives

Trivia

 * At the beginning of the level, Ellis complains to Nick about why he shot the helicopter pilot. Then they argue that the pilot was a zombie and that "he wouldn't help us very much" during that time. This seems to be a running joke with the Survivors.(Also a referance to Crash Course intro,which is Zoey and Francis are talking about the same thing.)
 * There is a jukebox easter egg in this level.
 * Near the ferry Crescendo event, there is a Charger strung up by all limbs.
 * A glitch can happen near the ferry Crescendo event where a charger can push a survivor into the water and cause them to get stuck only to eventually die once the other survivors move across on the ferry
