Hard Rain

Hard Rain is a new campaign for Left 4 Dead 2. Hard Rain takes place after Swamp Fever and supposedly is set in an Industrial Park that contains a sugar mill, based off the achievement Sob Story.

Trivia

 * Both the tagline and the campaign poster itself imply that this campaign may take place in areas that are at least partially flooded, likely due to heavy rain.
 * Hard Rain hosts a new Uncommon Common Infected, which ignores pipe-bombs.
 * The background of this poster implies that the survivors will have to go through an industrial zone of some sort.
 * Rochelle holds a scoped machine gun, most likely a MP5 Navy. This weapon is also in most Left 4 Dead posters, but is not in either Left 4 Dead or Left 4 Dead 2.
 * First Gameplay Footage: Footage
 * A rumored area in this campaign is known as the sugar mill, due to the achievement Sob Story where one must navigate the sugar mill without killing any Witches. It is assumed that this chapter or level section could be a lot like the impound lot level section, except with Witches.
 * Given that the campaign that follows this one chronologically, The Parish, starts out on a dock, it is reasonable to assume that the escape vehicle in this campaign will be another boat of some kind.
 * The name could be a reference to the film, Hard Rain, which involved a town dealing with a flood.
 * This is the first campaign in which both the Survivor's loss of equipment during the introduction is explained, and the first in which both their means of arrival, and means of escape is identical.
