The Plantation

The Plantation is the fourth and final chapter in Swamp Fever. In this finale, the Survivors must hold out through wave after wave of infected in a two story plantation house until Virgil arrives to take them up river. This finale is similar to those from Left 4 Dead, but is unique in that the survivors will likely have to fight two tanks simultaneously right before the rescue vehicle arrives.

The Heavy Machine Gun on the second floor has a limited firing arc, it can only view out into the plantation fields, and cannot cover any part of the house itself. When the boat comes and the door explode open, jumping from the balcony to the ground below incapacitates the survivor. Move down the stairs.

Trivia

 * In the video showcasing the chapter, once the Survivors entered the boat, other incapacitated Survivors were automatically transferred inside the boat. This was most likely due to a coding error, as the game was still in its beta stage.
 * This is the only chapter of the campaign set in daylight, because the Sun is visible in the sky. Earlier chapters took place just before the Sun had risen. Witches in this level are stationary, likely for consistency reasons.
 * This level is featured in the Zombie Survival Guide. Though, strangely, the HMG is located in another place - near to the front door of the plantation, and the Fallen Survivors are seen there, even though they are cut and were supposed to be in Dead Center. The Fallen Survivor is, also, not wearing a hat like the ones in-game.
 * During the finale, the survivors may face up to a total of four tanks, a first one much like the finales of Left 4 Dead, a pair of tanks, one arriving a few moments after the other, most likely forcing the survivors to fight the two of them at once, and a final avoidable one that shows up in the final wave that comes once Virgilarrives with the boat.
 * Near the mansion during the finale, there is a crate that allows you to restock ammo while holding off infected. If you observe carefully at the side of the crate you will see the words, "Ration K US 120 Rations". These also appear in Dead Air. Ration K does not currently exist in the US Army, however. It once used to exist in the US Army during World War II as rations for paratroopers during operations. It was canceled due to being overused by soldiers resulting in cases of vitamin deficiency and malnourishment. This can likely be explained by Valve reusing models from its World War 2 game, Day of Defeat Source.
 * This chapter is one of few to feature the new Heavy Machine Gun, located on the balcony of the plantation, overlooking the garden. Ironically, it is almost useless, as of most of the horde coming from the back and the sides where there is no way to get them with a Heavy Machine Gun, and the ones who come through the garden maze are still protected by the garden maze. Tanks also appear to be unslowed by the fire, unlike the first game.
 * Next to the hole that leads into the plantation, there are 4 teddy bears leaning against the wall. This could be a subtle reference to how there are four Survivors.
