Lore & Background
In the wake of the initial outbreak, chaos has consumed major American cities. Fairfield becomes a focal point where desperate individuals converge hoping to find safety or transport out of the quarantine zone. The campaign begins with all four survivors already together in the safe room of the first building, bound together not by friendship but by the immediate necessity of staying alive against hordes of infected citizens. Bill, a veteran with military experience, naturally takes command, organizing the group's movements through dangerous urban environments.
Their goal is to reach a helicopter extraction point on the rooftop of Mercy Hospital. This campaign highlights their contrasting personalities: Louis is an office worker and optimist, Francis is tough and skeptical, Zoey is a college student and horror movie fan who is often sarcastic or frightened, and Bill acts as the weary anchor holding them together. The events of this timeline are crucial because they mark the first successful escape from a major infested zone for this specific quartet.
Their survival here proves their compatibility as a team, setting the precedent for the harder challenges they will face in the weeks that follow across the American northeast.
