In Decay/Chapter 1.3: Recruitment

Survivor Hunting is the fifth phase of Eternal Terror and appears in Chapter 1. While the player can take up as much time as possible activating this phase, it technically begins only a few minutes after Chapter 1.2: The Formation, inside Cybertron Collectibles. This phase features the first compulsory Maniac battle, Bradley King. After this phase, players are free to roam to town of Dusty Springs.

Level Description
"With DS3 formed, and everybody safe for now, they need to start searching deeper into the town. It seems that there are survivors at St. Mark's Church, and with more people meaning a higher chance of survival, it is apparent that the church must be searched. There is no promise that these potential survivors will be friendly however, but sometimes there are risks that need to be taken."
