Millhaven



Millhaven is a military outpost first mentioned in the Left 4 Dead comic The Sacrifice based on the DLC campaign of the same name, where Bill, Zoey, Francis, and Louis are taken after they are rescued by the Military at the Farmhouse. Once they arrive the Survivors are woken up and ordered at gunpoint to leave their weapons behind and are marched out of the rescue vehicle where they are met with aggressive military personnel, who immediately do not get along with Francis and threaten to shoot anybody who tries to run away. A military personnel tells them they are going to "testing", to which Zoey reacts to nervously. The Military locks Francis and Louis up in a cell together and sent Zoey and Bill to a doctor. The guards to Louis and Francis's cell ask them what they saw since they've been fighting infected for 2 weeks and they asked if the infected are mutating. It is confirmed that they don't know anything about the Special Infected and the boss doesn't believe in it. Meanwhile, Zoey and Bill are being checked by a doctor (testing) to see if they are carriers, which all 4 are. The doctor decides to help Bill and Zoey escape while the guards help Francis and Louis escape.

More about Millhaven will likely be known as the comics continue to get released.

In The Parish in Left 4 Dead 2, it is stated that the Military is killing off any Carriers of the Infection, this might explain the large amount of dead bodies outside the outpost, unless they are infected. However in the Sacrifice comic, it seems the military is simply trying to contain the carriers so they can't infect others, while testing them to try and get a cure to the infection.
