Eventually, Hayden finds Yargo, who gives Hayden his updated orders and a booster for the infection. Hayden refuses the medicine, and learns that Mezner wants to recapture the infected with an old transmitter, which emits a signal that attracts Technocyte-infected creatures to its location, within an old church. Hayden also learns that Nadia, a woman Hayden is acquainted with, is also working for Mezner. Hayden moves on towards the church to destroy the transmitter, eliminating both Lasrian soldiers and infected along the way. Eventually, he makes it into the church catacombs and finds the transmitter. Nadia, who has a deep-rooted hatred for Hayden after his last meeting with her, confronts him. She leaves him to fight his way through a swarm of infected and escape before the C4 he set goes off.
