The Milltown

The Milltown is the first map of the Hard Rain campaign.

The Survivors realize that they do not have enough gas to make it to New Orleans. Virgil drops the Survivors off at a Burger Tank, tasking them to retrieve some gas from the nearby gas station. However, once the Survivors get to the gas station, it has been depleted of all fuel and the only remaining gas is two miles away. The Survivors must walk across yards and through homes, paying close attention to the landmarks while fighting the Infected. They walk past a playground, a garage sale and then eventually find a road that leads to a nearby safe room.

Trivia

 * The Burger Tank has 4 first-aid kits plus a medical station that may yield additional medkits. However, a tooltip warns the Survivors to leave some supplies for the return trip, as they will eventually return to the Burger Tank during the finale.
 * A playground can be found in this level, but it is only littered with the corpses of the Common Infected, leaving it up to question on what happened to the children of the town.
 * It starts raining as soon as the Survivors pass the empty gas station.
 * The presence of the Uncommon Common Worker Infected is explained about half way through the level, when the player pass by a partially built construction site.
 * Even if the Survivors take all the medkits in the safe room, there will be two medkits when you return to this chapter.
 * You will pass a house with two blocked doors at the beginning of the level. It later serves as a Safe Room in Return to Town. It is later seen that the barricades fell off, acting as a "welcome carpet", unveiling the safe room doors behind them.
 * It is revealed at times that the Survivors forgot their weaponry on Virgil's boat in a "gun bag" that Nick was in charge of. This is one of the only campaigns where it is explicitly stated why the Survivors do not have the supplies from the last campaign. It is implied in other campaigns that the Survivors lost the guns in a helicopter crash or something similar to that.
 * When passing the house that serves as the safe room for the finale, AI Survivors will reach through the wall of the house, getting the Tier 2 weaponry that has already spawned in the room.
