The Swamp

"This swamp is gonna mess up my white suit!"

- Nick

The Swamp is the second chapter of the campaign Swamp Fever in Left 4 Dead 2. It begins in a train underpass fashioned into a safe room for the first chapter. The Survivors temporarily touch ground, but then move on to planks resting over the water. Once the planks end, the group finds the ruins of a long abandoned boat house and a dock, which happens to be loaded with various supplies. Nearby, there is a plume of smoke above the trees. The path leads into a clearing with a crashed plane. On the way to the plane the survivors can find a parachutist, dead, stuck in the trees and occasionally find tier 2 weaponry near the dead parachutist. Fortunately, the aircraft is filled with supplies. The crash has slowed the Survivors' progress, however, and they must open the emergency exit to proceed—which, of course, triggers a Crescendo Event. Once they have weathered the hordes of the Infected, the group makes their way through some ravaged old shacks and into the next safe house.

All campaign walkthroughs are done on Normal Difficulty in single player, and are meant to give tips on what to do and generally point out things that might otherwise be missed.

There are, of course, a few key things to always remember:
 * Stop, look, and listen.
 * Stopping to observe your surroundings might allow you to prepare for something nasty, like a Witch or Special Infected in a really bad place for them to be. Maybe even a Tank at possible times.
 * Teamwork.
 * This cannot be stressed enough. Left 4 Dead 2 is supposed to be a cooperative game. Communicate with your teammates, if you're playing with others, or if you're by yourself with the AI, point out things they might otherwise miss. In all cases, watch out for each other and take care of each other. You are not going to survive the zombie apocalypse by yourself.
 * Be ready for anything.
 * Don't panic.

Campaign
The Survivors start out in a train underpass filled with weapons, first-aid kits, and ammunition. Grab what you need, open the door, and venture into the zombie filled swamp water.

Shoot the zombies in this small section of swamp, then continue through the water or on the strip of land to the right until you reach a boat. Inside the boat may be some supplies, depending on what the AI Director places. There is usually an axe in the tree right next to the boat also. Continue forward and through the horde-infested swamp. There is a dead parachutist found hanging in the trees here. There may be weapons or a grenade attached to him. Walk a little further and you'll reach a dock, filled with various supplies.

After stocking up on supplies at the dock, continue forward and there is a crashed aircraft in the way of the Survivors. Once your ready, open the emergency door, which triggers a crescendo event. After fighting hordes of zombies, jump down off the wing and you'll come across a shack. There are usually first-aid kits and weapons here. Sometimes there are items outside the shack near the fire pit. Continue forward where you reach more broken down shacks, filled with supplies. After clearing some zombies, the safe room is right ahead. Close the door, take a breath,and get prepared for The Shantytown.
