Hard Rain

Hard Rain is the fifth (fourth if you don't have The Passing DLC) campaign in Left 4 Dead 2, taking place after Swamp Fever. This is the only campaign where you must travel back to previous visited safehouses. It is set in the riverside town of Ducatel, Mississippi as a hurricane approaches. At the start of the campaign, Virgil drops off the Survivors, with a mission to find and bring back gas for his boat. They must travel through the abandoned town of Ducatel, its old, witch-infested Sugar Mill of the Ducatel sugar company and its sugar-cane fields to reach "Ducatel Diesel" gas station. Once they have the diesel, it starts storming and raining heavily, forcing them to travel back through the sugar mill and town to get back the dock in knee deep water while carrying the green gas canisters on their backs. When they finally reach the docks to signal Virgil, they climb to the roof of a nearby Burger Tank to turn on the sign, using it as a signal.

This campaign's Uncommon Infected are the Infected Workers, which can take more damage and are not attracted to Pipe bombs (as their worker headgear prevents sound from alerting them) but are still attracted to Bile bombs.

Behind the Scenes

 * In early development of the campaign, the design was to have the Survivors travel much further than Burger Tank, which is very close, to get weapons. It was discovered that players often faltered before retrieving weapons in time.
 * According to Chet Faliszek at EuroGamer Expo London, early builds of the campaign had the players turn on the lights of houses and other areas on the way to the gas station so that they will be lit on the way back, but players found this to be a menial task, and so the idea was scrapped. The lights turn on automatically now.
