Campaing starts off in a junkyard as the survivors exit the bus they thought they would be traveling to saftey on.
In this campaign the players will have to make their way through several locations, to get to the supposedly last safe spot, which is a mental asylum - oddly. The first map of this campaign is now done and a small part of the second one is in this package, too.
The map starts inside a sewer-complex that ends at the entrance to a research-facility. After heading trough the overrun complex, the survivors will hopefully arrive the saferoom.

Barricade Builder Map V2.1
Version 2.1 of the Barricade Builder Map.
Reaper's Garage v1.2
The survivors find themselves in a once safe-haven evacuation zone underground, only to find it's been overrun. It's a bit dark, why not fire up the generator and get some lights?
Thanks to Francis the survivors has gotten themselves trapped inside of an old storage facility, it's dark! Try to turn the lights on!
Defend yourself inside (or outside) the small radio station. Block the windows and doors and play the music. Use the car alarms to draw the infected away from you. And watch out for lightning strikes.
