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. 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 diesel fuel for his boat. They must travel to the Ducatel Diesel gas station through the abandoned town of Ducatel, the Witch infested ruins of the Ducatel Sugar Company mill and a cane field. Once they have the diesel, the hurricane hits and the area immediately floods obliging the Survivors to retrace their steps through knee-deep water, squalls of wind and rain and failing visibility. When they finally reach Ducatel they signal Virgil to return and pick them up by switching on a nearby Burger Tank roof sign: thereby triggering the campaign's finale.

This campaign features the Worker Infected who are denoted by yellow safety helmets and reflective vests. They can take more damage than Common Infected and are not attracted to Pipe bombs because they wear ear protection that prevents them from hearing this grenade's distinctive sound.

Behind the Scenes

 * Initially the Survivors had to travel some distance into the initial chapter to get weapons. During play testing it was found players were hesitant to do this, thus failing to get to up-graded weapons in time.  This problem was overcome by putting weapons and supplies in the nearby Burger Tank.
 * 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.
